    If you need simple interface to DOM check out phpQuery - jQuery port to PHP:
    http://code.google.com/p/phpquery/

    It uses CSS selectors to fetch nodes.
    Here's example how it works:
    <?php
    // just one file to include
    require('phpQuery/phpQuery.php');

    $html = '
    <div>
        mydiv
        <ul>
            <li>1</li>
            <li>2</li>
            <li>3</li>
        </ul>
    </div>'    ;

    // intialize new DOM from markup
    phpQuery::newDocument($markup)
        ->    find('ul > li')
            ->    addClass('my-new-class')
            ->    filter(':last')
                ->    addClass('last-li');

    // query all unordered lists in last used DOM
    pq('ul')->insertAfter('div');

    // iterate all LIs from last used DOM
    foreach(pq('li') as $li) {
            // iteration returns plain DOM nodes, not phpQuery objects
            pq($li)->addClass('my-second-new-class');
    }

    // same as pq('anything')->htmlOuter()
    // but on document root (returns doctype etc)
    print phpQuery::getDocument();
    ?>

    It uses DOM extension and XPath so it works only in PHP5.

    When I tried to parse my XHTML Strict files with DOM extension, it couldn't understand xhtml entities (like &copy;). I found post about it here (14-Jul-2005 09:05) which adviced to add resolveExternals = true, but it was very slow. There was some small note about xml catalogs but without any glue. Here it is:

    XML catalogs is something like cache. Download all needed dtd's to /etc/xml, edit file /etc/xml/catalog and add this line: <public publicId="-//W3C//DTD XHTML 1.0 Strict//EN" uri="file:///etc/xml/xhtml1-strict.dtd" />

    Thats all. Thanks to http://www.whump.com/moreLikeThis/link/03815

    I hate DOM model !
    so I wrote dom2array simple function (simple for use):

    function dom2array($node) {
      $res = array();
      print $node->nodeType.'<br/>';
      if($node->nodeType == XML_TEXT_NODE){
          $res = $node->nodeValue;
      }
      else{
          if($node->hasAttributes()){
              $attributes = $node->attributes;
              if(!is_null($attributes)){
                  $res['@attributes'] = array();
                  foreach ($attributes as $index=>$attr) {
                      $res['@attributes'][$attr->name] = $attr->value;
                  }
              }
          }
          if($node->hasChildNodes()){
              $children = $node->childNodes;
              for($i=0;$i<$children->length;$i++){
                  $child = $children->item($i);
                  $res[$child->nodeName] = dom2array($child);
              }
          }
      }
      return $res;
    }

    The project I'm currently working on uses XPaths to dynamically navigate through chunks of an XML file.  I couldn't find any PHP code on the net that would build the XPath to a node for me, so I wrote my own function.  Turns out it wasn't as hard as I thought it might be (yay recursion), though it does entail using some PHP shenanigans... 

    Hopefully it'll save someone else the trouble of reinventing this wheel.

    <?php
            function getNodeXPath( $node ) {
                // REMEMBER THAT XPATHS USE BASE-1 INSTEAD OF BASE-0!!!
           
            // Get the index for the current node by looping through the siblings.
                $parentNode = $node->parentNode;
            if(     $parentNode != null ) {
                    $nodeIndex = 0;
                do {
                        $testNode = $parentNode->childNodes->item( $nodeIndex );
                        $nodeName = $testNode->nodeName;
                        $nodeIndex++;
                   
                        // PHP trickery!  Here we create a counter based on the node
                    //  name of the test node to use in the XPath.
                        if( !isset( $$nodeName ) ) $$nodeName = 1;
                    else $    $nodeName++;
                   
                        // Failsafe return value.
                        if( $nodeIndex > $parentNode->childNodes->length ) return( "/" );
                } while( !    $node->isSameNode( $testNode ) );
               
                    // Recursively get the XPath for the parent.
                    return( getNodeXPath( $parentNode ) . "/{$node->nodeName}[{$$nodeName}]" );
            } else {
                    // Hit the root node!  Note that the slash is added when
                //  building the XPath, so we return just an empty string.
                    return( "" );
            }
        }
    ?>

    If  you want to print the DOM XML file content, you can use the next code:

    $doc = new DOMDocument();
    $doc->load($xmlFileName);
    echo "<br>" . $doc->documentURI;
    $x = $doc->documentElement;
    getNodeContent($x->childNodes, 0);

    function getNodeContent($nodes, $level){
        foreach ($nodes AS $item) {
        //  print "<br><br>TIPO: " . $item->nodeType ;
          printValues($item, $level);
          if ($item->nodeType == 1) { //DOMElement
              foreach ($item->attributes AS $itemAtt) {
                  printValues($itemAtt, $level+3);
              }
              if($item->childNodes || $item->childNodes->lenth > 0) {
                  getNodeContent($item->childNodes, $level+5);
              }
          }
        }
    }

    function printValues($item, $level){
        if ($item->nodeType == 1) { //DOMElement
            printLevel($level);
            print $item->nodeName . " = " . $item->nodeValue;
        }
        if ($item->nodeType == 2) { //DOMAttr
            printLevel($level);
            print $item->name . " = " . $item->value ;
        }
        if ($item->nodeType == 3) { //DOMText
          if ($item->isWhitespaceInElementContent() == false){
            printLevel($level);
            print $item->wholeText ;
          }
        }
    }

    function printLevel($level)
    {
        print "<br>";
        if ($level == 0) {
            print "<br>";
        }
        for($i=0; $i < $level; $i++) {
            print "-";
        }
    }

    As of PHP 5.1, libxml options may be set using constants rather than the use of proprietary DomDocument properties.

    DomDocument->resolveExternals is equivilant to setting
    LIBXML_DTDLOAD
    LIBXML_DTDATTR

    DomDocument->validateOnParse is equivilant to setting
    LIBXML_DTDLOAD
    LIBXML_DTDVALID

    PHP 5.1 users are encouraged to use the new constants.

    Example:

    DomDocument->load($file, LIBXML_DTDLOAD|LIBXML_DTDATTR);

    DomDocument->load($file, LIBXML_DTDLOAD|LIBXML_DTDVALID);

    If you want to  use DOMDocument in your PHPUnit Tests drive on Symfony Controller (testing form)! Use like :

    namespace Tests\YourBundle\Controller;

    use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
    use YourBundle\Controller\TextController;

    class DefaultControllerTest extends WebTestCase
    {
        public function testIndex()
        {
            $client = static::createClient(array(), array());

            $crawler = $client->request('GET', '/text/add');
            $this->assertTrue($crawler->filter("form")->count() > 0, "Text form exist !");

            $form = $crawler->filter("form")->form();

            $domDocument = new \DOMDocument;

            $domInput = $domDocument->createElement('input');
            $dom = $domDocument->appendChild($domInput);
            $dom->setAttribute('slug', 'bloc');
          

            $formInput = new \Symfony\Component\DomCrawler\Field\InputFormField($domInput);
            $form->set($formInput);

            $crawler = $client->submit($form);
               
            if ($client->getResponse()->isRedirect())
            {
                $crawler = $client->followRedirect(false);
            }

           // $this->assertTrue($client->getResponse()->isSuccessful());
            //$this->assertEquals(200, $client->getResponse()->getStatusCode(),
            //             "Unexpected HTTP status code for GET /backoffice/login");

    If you are using not object-oriented functions and it takes too much time to change them all (or you'll be replacing them later) then as a temporary decision can be used this modules:

    For DOM XML:
    http://alexandre.alapetite.net/doc-alex/domxml-php4-php5/

    For XSLT:
    http://alexandre.alapetite.net/doc-alex/xslt-php4-php5/

    When dealing with validation or loading, the output errors can be quite annoying.

    PHP 5.1 introduces libxml_get_errors().

    Being an experienced ASP developer I was wondering how to replace textual content of a node (with msxml this is simply acheived by setting the 'text' property of a node). Out of frustration I started to play around with SimpleXml but I could not get it to work in combination with xPath.

    I took me a lot of time to find out so I hope this helps others:

    function replaceNodeText($objXml, $objNode, $strNewContent){
        /*
        This function replaces a node's string content with strNewContent
        */
        $objNodeListNested = &$objNode->childNodes;
        foreach ( $objNodeListNested as $objNodeNested ){
             if ($objNodeNested->nodeType == XML_TEXT_NODE)$objNode->removeChild ($objNodeNested);
        }
       
        $objNode->appendChild($objXml->createTextNode($strNewContent));
    }

    $objXml= new DOMDocument();
    $objXml->loadXML('<root><node id="1">bla</note></root>');
    $objXpath = new domxpath($objXml);

    $strXpath="/root/node[@id='1']";
    $objNodeList = $objXpath ->query($strXpath);
    foreach ($objNodeList as $objNode){
    //pass the node by reference
    replaceNodeText($objXml, &$objNode, $strImportedValue);
    }

    This module is not included by default either in the CentOS 4 "centosplus" repository. For those using PHP5 on CentOS 4, a simple "yum --enablerepo=centosplus install php-xml" will do the trick (this will install both the XML and DOM modules).

    The Yanik's dom2array() function (added on 14-Mar-2007 08:40) does not handle multiple nodes with the same name, i.e.:

    <foo>
      <name>aa</name>
      <name>bb</name>
    </foo>

    It will overwrite former and your array will contain just the last one ("bb")

    This particular W3C page provides invaluable documentation for the DOM classes implemented in php5 (via libxml2). It fills in plenty of php.net's gaps:

    http://www.w3.org/TR/DOM-Level-2-Core/core.html

    Some key examples:
    * concise summary of the class heirachy (1.1.1)
    * clarification that DOM level 2 doesn't allow for population of internal DTDs
    * explanation of DOMNode->normalize()
    * explanation of the DOMImplementation class

    The interfaces are described in OMG's Interface Definition Language

    After searching how to extend the DOMDocument and DOMElement I found a way in the bug: http://bugs.php.net/bug.php?id=35104. The following code shows how:

    <?php
    class extDOMDocument extends DOMDocument {
    public function     createElement($name, $value=null) {
          $orphan = new extDOMElement($name, $value); // new  sub-class object
          $docFragment = $this->createDocumentFragment(); // lightweight container maintains "ownerDocument"
          $docFragment->appendChild($orphan); // attach
          $ret = $docFragment->removeChild($orphan); // remove
          return $ret; // ownerDocument set; won't be destroyed on  method exit
    }
    // .. more class definition
    }

    class     extDOMElement extends DOMElement {
    function     __construct($name, $value='', $namespaceURI=null) {
          parent::__construct($name, $value, $namespaceURI);
    }
          //  ... more class definition here
    }

    $doc = new extDOMDocument('test');
    $el = $doc->createElement('tagname');
    $el->setAttribute("attr", "val");
    $doc->appendChild($el);

    // append discards the DOMDocumentFragment and just adds its child nodes, but ownerDocument is maintained.
    echo get_class($el)."<br/>";
    echo     get_class($doc->documentElement)."<br/>";
    echo     "<xmp>".$doc->saveXML()."</xmp>";

    I had problems with the dom2array_full function by "nospam at ya dot ru". Here's my function, which works correctly for my project, and might work for yours:

    <?php
    function dom_to_array($root)
    {
            $result = array();

        if (    $root->hasAttributes())
        {
                $attrs = $root->attributes;

            foreach (    $attrs as $i => $attr)
                    $result[$attr->name] = $attr->value;
        }

            $children = $root->childNodes;

        if (    $children->length == 1)
        {
                $child = $children->item(0);

            if (    $child->nodeType == XML_TEXT_NODE)
            {
                    $result['_value'] = $child->nodeValue;

                if (    count($result) == 1)
                    return     $result['_value'];
                else
                    return     $result;
            }
        }

            $group = array();

        for(    $i = 0; $i < $children->length; $i++)
        {
                $child = $children->item($i);

            if (!isset(    $result[$child->nodeName]))

    Here is a fast innerHTML function that returns the result without iterating over child nodes.

    <?php
    function innerHTML($el) {
          $doc = new DOMDocument();
          $doc->appendChild($doc->importNode($el, TRUE));
          $html = trim($doc->saveHTML());
          $tag = $el->nodeName;
      return     preg_replace('@^<' . $tag . '[^>]*>|</' . $tag . '>$@', '', $html);
    }
    ?>

    Example
    <?php
    $doc     = new DOMDocument();
    // A corrupt HTML string
    $doc->loadHTML('<HTML><A HREF="ss">asd</A>');
    $body = $doc->getElementsByTagName('body')->item(0);
    print     htmlspecialchars(innerHTML($body));
    // Prints <a href="ss">asd</a>

    I wrote a framework to implement the StyleSheet interfaces as specified on the W3C website.  The code is written in PHP, and is NOT a complete implementation.  Use it how ya like.  I was planning on adding the CSSStyleSheet interfaces as well.  Feel free to ask.

    A function among several others to parse a google results page, I wrote this some time ago - google has probably changed their site since then, but I thought this might be helpful to someone.

    I'm moving servers, but I will probably throw this up on my blog when I get it back up.

    <?php

    function googleResult($listItem) {
            // given a LIST ITEM element, this will validate, and return an array for that LI entry as an inline result from google.
        /*
         * <li class='g w0'>
         *   <h3 class='r'>
         *     <a href='the URL' class='l'>
         *       Description <em>description</em>
         *     </a>
         *   </h3>
         * </li>
         *
           UPDATE:
           This function will now look for any subcontainer that has an href, it doesn't have to be an H3
           this will make it work with a few more formatted search results.
         */

            $listItem = $listItem->childNodes;
                // Yes I don't use instanceof - I guess you'll have to deal.
            foreach($listItem as $element) {
            if(    is_object($element) && get_class($element) == 'DOMElement' && $element->hasChildNodes()) {
                    $hrefContainer = $element->childNodes;
                foreach(    $hrefContainer as $element2) {
                    if(    is_object($element2) && get_class($element2) == 'DOMElement' && $element2->nodeName == 'a' && $element2->hasAttribute('href')) {
                            $anchor = $element2;
                        unset(    $h3);
                        unset(    $element2);
                        break;
                    } else {
                          //print __LINE__ ." :: Breaking out of loop (normal result) element is not an annchor Element='".$element2->nodeName."'\n";

                return false;
        }

    You can get the "innerHTML" by nodeValue so

    <?php
        $doc     = new DOMDocument( );
            $ele = $doc->createElement( 'p', 'Sensei Ninja' );
        print     $ele->nodeValue;
    ?>

    You can even set it if you want

    <?php
        $doc     = new DOMDocument( );
            $ele = $doc->createElement( 'p' );
            $ele->nodeValue = 'Sensei Ninja';
            $doc->appendChild( $ele );
        print     $doc->saveHTML( );

    In response to "simlee at indiana dot edu",
    - First of all thanks for sharing your funciton.
    - It didn't work for me so i rewrite it from scratch using different method.

    Here is the new version, hope it helps someone :

    <?php
    /**
    * result sample : /html[1]/body[1]/span[1]/fieldset[1]/div[1]
    * @return string
    */
    function getNodeXPath( $node ) {   
            $result='';
        while (    $parentNode = $node->parentNode) {
                $nodeIndex=-1;
                $nodeTagIndex=0;
            do {
                    $nodeIndex++;
                    $testNode = $parentNode->childNodes->item( $nodeIndex );
                   
                if (    $testNode->nodeName==$node->nodeName and $testNode->parentNode->isSameNode($node->parentNode) and $testNode->childNodes->length>0) {
                        //echo "{$testNode->parentNode->nodeName}-{$testNode->nodeName}-{}<br/>";
                        $nodeTagIndex++;
                }
                   
            } while (!    $node->isSameNode($testNode));

                $result="/{$node->nodeName}[{$nodeTagIndex}]".$result;
                $node=$parentNode;

    I had the hardest time updating a complex XML document. Here's a quick example on how to do it.

    <?php

    // Load the XML from a file.
    $xml = "a2062.xml"; // This is an XFDL form previously unencoded and ungzipped.
    $dom = new DOMDocument();
    $dom->preserveWhiteSpace = false;
    $dom->Load($xml);

    // Create an XPath query.
    // Note: you must define the namespace if the XML document has defined namespaces.
    $xpath = new DOMXPath($dom);
    $xpath->registerNamespace('xfdl', "http://www.PureEdge.com/XFDL/6.5");

    // Locate the value for the first Item Description field.
    $query = "//xfdl:page/xfdl:field[@sid='ITEMDESA']/xfdl:value";
    $nodeList = $xpath->query($query);

    $nodeList->item(0)->nodeValue = "This is the text in the value node of the first Item Description field inside the DA 2062 PureEdge form.";

    $dom->save($xml);

    ?>

    I hope this helps someone.

    I found the xml2array function below very useful, but there seems to be a bug in it. The $item variable was never getting set. I've expanded this out to be a bit more readable, and the corrected code is :

    function xmlToArray($n)
    {
        $return=array();

        foreach($n->childNodes as $nc){
            if( $nc->hasChildNodes() ){
                if( $n->firstChild->nodeName== $n->lastChild->nodeName&&$n->childNodes->length>1){
                    $item = $n->firstChild;
                    $return[$nc->nodeName][]=$this->xmlToArray($item);
                }
                else{
                     $return[$nc->nodeName]=$this->xmlToArray($nc);
                }
           }
           else{
               $return=$nc->nodeValue;
           }
        }
        return $return;

    when you got variable nodes at start you array fails and looses nodes  beneath.
    solution that counts occurance though eats up performance:

    function xmlToArray($n)
    {
        $xml_array = array();
        $occurance = array();

         foreach($n->childNodes as $nc)
         {
             $occurance[$nc->nodeName]++;
         }
        
        foreach($n->childNodes as $nc){
            if( $nc->hasChildNodes() )
            {
                if($occurance[$nc->nodeName] > 1)
                {
                    $xml_array[$nc->nodeName][] = xmlToArray($nc);
                }
                else
                {

    I wrote a couple of functions to:
    - create a DOMDocument from a file
    - parse the namespaces in it
    - create a XPath object with all the namespaces registered
    - load the schemalocations
    - validate the file on the main schema (the one without prefix)

    It is useful for me, see if it is also for someone else!!

    Note that these DOM functions expect (and presumably return) all their data in UTF-8 character encoding, regardless of what PHP's current encoding is. This means that text nodes, attribute values etc, should be in utf8.

    This applies even if you're generating an XML document which is not ultimately in utf8.

    [Editor's Note: If you're using entities, then you have no choice. XML Catalogs can speed DTD resolution.]

    Never use

    $dom->resolveExternals=true;

    when parsing XHTML document that has the DOCTYPE declaration with DTD URL specified in it.

    Otherwise parsing the XHTML with DOCTYPE like this one:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

    will result in PHP/DOM downloading the DTD file from W3C site when parsing your document. It will add extra delay to your script - I experienced that $dom->load()'s total time was from 1 to 16 seconds.

    This extension allows editing an HTML snippet, for example removing an element:
    ‌‌$dom = new DOMDocument();
    ‌‌$dom->loadHTML('keep<b id="simple">REMOVE</b>');
    $‌‌remove = $dom->getElementById('simple');
    ‌‌$dom->removeChild($‌‌remove);
    echo ‌‌$dom->saveHTML();
    ...would output "keep".

    But it does not preserve formatting. If your code defines attributes using double quotes, saveHTML() may for instance return single quotes instead.

    The following can take a XML_TEXT_NODE node and return the contents in an array. Yanick's contribution rocks - but
    it overwrote with duplicates only keeping the last line
    in the returned array. All the other functions i tested from various sources failed to handle text nodes correctly. Hope this helps someone. It is adapted from code on this site.

    function myTextNode($n, &$a)
    {
    static $depth = 0;
    static $sz = '';

    if ($cn = $n->firstChild)
    {
      while ($cn)
      {
       if ($cn->nodeType == XML_TEXT_NODE)
       {
        $sz .= $cn->nodeValue;
       }
       elseif ($cn->nodeType == XML_ELEMENT_NODE)
       {
        $b = 1;
        if ($cn->hasChildNodes())
        {
         $depth++;
         if ($this->myHeadings($cn, $a))
         {
          if ($sz){
           array_push($a, $sz);
           $sz = '';
          }
         }
         $depth--;
        }
       }
       $cn = $cn->nextSibling;
      }
      return $b;
    }
    }

    so you could use:  

    $nodes = $dom->getElementsByTagName("td");
    if($nodes){
    foreach ($nodes as $node){
      $a = Array();
      myTextNode($node, $a);
    }
    }

    "If you create your own custom element extending DOMElement and append him in place of the document element, you cannot access to any new members newly defined in your custom class via DOMDocument::$documentElement."

    ... it is not a bug, it is a feature. The DOMDocument::$documentElement property name may be misleading but according to the DOM Level 2 Core specification it is a convenience attribute meant to access the root element of your DOMDocument. See here: http://www.w3.org/TR/DOM-Level-2-Core/core.html#i-Document

    I use DOM to generate dynamically XHTML document.

    When trying to extend the DOMDocument and DOMElement classes, I found a very annoying bug concerning DOMDocument::$documentElement.

    If you create your own custom element extending DOMElement and append him in place of the document element, you cannot access to any new members newly defined in your custom class via DOMDocument::$documentElement.

    In my situation, I cannot use DOMDocument::registerNodeClass() because the document element is not necessarily the base class for all the elements in my document.

    *******
    problem
    *******

    See bellow for the repro step:

    <?php
            class MyElement extends DOMElement{
            public     $myProp="myProp";
            public function     myMethod(){
                return     'myMethod()';
            }
        }
       
            $myDocument=new DOMDocument();
            $myDocument->appendChild(new MyElement('myElement','myElement'));
        echo (    '$myElement->myProp :'.$myDocument->documentElement->myProp.'<br />');
        echo (    '$myElement->myMethod :'.$myDocument->documentElement->myMethod().'<br />');
    ?>

    will output:

    Notice: Undefined property: DOMElement::$myProp in C:\Program Files\EasyPHP 2.0b1\www\testDOMBug\test2.php on line 11
    $myElement->myProp :

    Fatal error: Call to undefined method DOMElement::myMethod() in C:\Program Files\EasyPHP 2.0b1\www\testDOMBug\test2.php on line 12

    *******
    solution
    *******

    After searching around, I found a pretty odd way to fix this problem. It seems that you have to stock a reference to your appended document element in an user-defined (and persistent) variable (in other words, not only in DOMDocument::$documentElement). See below:

    <?php   
            class MyElement extends DOMElement{
            public     $myProp="myProp";
            public function     myMethod(){
                return     'myMethod()';
            }
        }
       
            $myDocument=new DOMDocument();
            $mydocumentElement=$myDocument->appendChild(new MyElement('myElement','myElement')); //here is the hack
            echo ('$myElement->myProp :'.$myDocument->documentElement->myProp.'<br />');
        echo (    '$myElement->myMethod :'.$myDocument->documentElement->myMethod().'<br />');
    ?>

    will output:

    $myElement->myProp :myProp
    $myElement->myMethod :myMethod()

    Hope it will help.

    In response to lutfi at smartconsultant dot us :

    (see my post on
    http://fr2.php.net/manual/en/
    function.dom-domdocument-getelementsbytagname.php
    )

    Use this class I wrote:

    class XPathableNode extends DOMNode
    {
        protected $Node;
        protected $DOMDocument_from_node;
        protected $DOMXpath_for_node;

        public function __construct(/* DOMNode */ $node)
        {
            $this->Node=$node;
            $this->DOMDocument_from_node=new
                                                              DomDocument();
            $domNode=$this->DOMDocument_from_node
                                      ->importNode($this->Node, true);
            $this->DOMDocument_from_node
                                     ->appendChild($domNode);
            $this->DomXpath_for_node =
                        new Domxpath($this->
                                             DOMDocument_from_node);
        }

        public function convertHTML()
        {    return $this->DOMDocument_from_node
                                                                 ->saveHTML();
        }

        public /*DomNodeList*/ function applyXpath($xpath)
        {    return $this->DomXpath_for_node
                                                           ->query($xpath);
        }
    }

    (sorry for the display... What a terrible hinderance on the
    part of php.net !)

    Then :
    Make a new XPathableNode out of your parent node.
    You may then retrieve a DOMNodeList from it by applying a
    xpath (thus being able to specify the depth  and name of
    elements you want).

    Has got me around some (of the many) DOM awkwardnesses a few times.

    I needed a function that quickly converts an xml with key/value pairs to an array.

    for example:
    <?xml version="1.0" encoding="UTF-8"?>
    <test>
        <key id="Array key #1" value="Value #1"/>
        <key id="Array key #2" value="Value #2"/>
        <key id="Dupe" value="Duplicate keys"/>
        <key id="Dupe" value="create numeric arrays"/>
        <key id="And another key">
            <![CDATA[
                Multiline
                data
                works
                just
                as
                well.
            ]]>
        </key>
        <nested>
            <key id="Nested key" value="Nested data works as well, but it still results in a 1 dimensional array."/>
        </nested>
    </test>

    Results in the following array:
    array(5) {
      ["Array key #1"]=>
      string(8) "Value #1"
      ["Array key #2"]=>
      string(8) "Value #2"
      ["Dupe"]=>
      array(2) {
        [0]=>
        string(14) "Duplicate keys"
        [1]=>
        string(21) "create numeric arrays"
      }
      ["And another key"]=>
      string(49) "Multiline
                data
                works
                just
                as
                well."
      ["Nested key"]=>
      string(73) "Nested data works as well, but it still results in a 1 dimensional array."
    }

    Here's the code:
    <?php
            function xml2array($xml) {
                $domDocument = new DOMDocument;
                $domDocument->loadXML($xml);
                $domXPath = new DOMXPath($domDocument);
                $array = array();
            foreach (    $domXPath->query('//key') as $keyDOM) {
                    $id = $keyDOM->getAttribute('id');
                    $value = $keyDOM->hasAttribute('value') ? $keyDOM->getAttribute('value') : trim($keyDOM->textContent);
                if (    array_key_exists($id, $array)) {
                    if (    is_array($array[$id])) {
                            $array[$id][] = $value;
                    } else {
                            $array[$id] = array($array[$id]);
                            $array[$id][] = $value;
                    }
                } else {
                        $array[$id] = $value;
                }
            }
            return     $array;
        }
    ?>

    Array to DOM

    Here is a recursive function to turn a multidimensional array into an XML document.  It will handle multiple elements of the same tag, but only one per parent element. IE:

    Can't generate:         Can generate:
    <root>                  <root>
      <sub1>data1</sub1>      <subs1>
      <sub1>data2</sub1>         <value>data1</value>
      <sub2>data1</sub2>         <value>data2</value>
      <sub2>data2</sub2>      </subs1>
    </root>                   <subs2>
                                <value>data1</value>
                                <value>data2</value>
                              <subs2>
                            </root>

    Also, the function performs no type of error checking on your array and will throw a DOMException if a key value you used in your array contains invalid characters for a proper DOM tag. This function is untested for "deep" multidimensional arrays.

    Complete code ready to run with example:

    <?PHP
          function AtoX($array, $DOM=null, $root=null){
       
        if(    $DOM  == null){$DOM  = new DOMDocument('1.0', 'iso-8859-1');}
        if(    $root == null){$root = $DOM->appendChild($DOM->createElement('root'));}
       
            $name = $array['#MULTIPLE_ELEMENT_NAME'];

          foreach(    $array as $key => $value){   
            if(    is_int($key) && $name != null){
              if(    is_array($value)){
                    $subroot = $root->appendChild($DOM->createElement($name));
                    AtoX($value, $DOM, $subroot);
              }
              else if(    is_scalar($value)){
                    $root->appendChild($DOM->createElement($name, $value));
              }
            }
            else if(    is_string($key) && $key != '#MULTIPLE_ELEMENT_NAME'){
              if(    is_array($value)){
                    $subroot = $root->appendChild($DOM->createElement($key));
                    AtoX($value, $DOM, $subroot);
              }
              else if(    is_scalar($value)){
                    $root->appendChild($DOM->createElement($key, $value));
