Özellikler

actualEncoding: Kullanımı önerilmiyor. encoding özelliğinin salt okunur eşdeğeri olarak belgenin asıl kodlaması.
childElementCount: Çocuk elemanların sayısı.
config: Kullanımı önerilmiyor. DOMDocument::normalizeDocument() çağrıldığında kullanılan yapılandırma.
doctype: Bu belgenin Belge Türü Bildirimi.
documentElement: İlk belge elemanı olarak DOMElement nesnesi. Böyle bir eleman yoksa değeri null olur.
documentURI: Belgenin bulunduğu yer; tanımlanmamışsa null'dur.
encoding: Belgenin XMl bildiriminde belirtilen karakter kodlaması. Bu öznitelik 3. seviye DOM belirtiminin son sürümünde yoktur, ancak bu gerçeklenimin XML belge kodlamasını bir yerde belirtmesi gerekiyordu ve tek yol buydu.
firstElementChild: İlk çocuk eleman ya da null.
formatOutput: Çıktı, girintiler ve ek boşluklarla daha hoş biçemlenir. Belge preserveWhitespace etkin olarak yüklenmişse bunun bir etkisi yoktur.
implementation: Belgenin elde edilmesinde kullanılan DOMImplementation nesnesi.
lastElementChild: Son çocuk eleman ya da null.
preserveWhiteSpace: Fazladan boşluklar silinmez. Ön tanımlı değer: true. Buna false atamakla DOMDocument::load()'a option olarak LIBXML_NOBLANKS atamak aynı etkiye sahiptir.
recover: Tescilli. Kurtarma kipini etkin kılar. Yani, iyi biçemli olmayan belgeler de çözümlenmeye çalışılır. Bu öznitelik DOM belirtiminin bir parçası değildir; libxml'e özgüdür.
resolveExternals: Bir belge türü bildirimindeki harici öğeleri yüklemek için true atayın. Karakter öğelerini XML belgeye dahil etmek için yararlıdır.
standalone: Kullanımı önerilmiyor. XML bildiriminde belirtildiği gibi, belgenin tek bir belgeden oluşup oluşmadığını belirtir. xmlStandalone özniteliğine karşılıktır.
strictErrorChecking: Hata durumunda DOMException oluşur. Ön tanımlı değer: true.
substituteEntities: Tescilli. Öğelerin ikame edilip edilmeyeceği. Bu öznitelik DOM belirtiminin bir parçası değildir; libxml'e özgüdür. Ön tanımlı değer: false.

Dikkat
Öğe ikamesi, XML Harici Öğe (XXE) saldırılarını kolaylaştırabilir.
validateOnParse: Belge DTD'ye uygun olarak doğrulanır ve yüklenir. Ön tanımlı değer: false.

Dikkat
DTD doğrulamasının etkinleştirilmesi, XML Harici Varlık (XXE) saldırılarını kolaylaştırabilir.
version: Kullanımı önerilmiyor. xmlVersion özelliğinin karşılığı olarak XML sürümü.
xmlEncoding: Belgenin karakter kodlaması olarak, XML bildiriminde belirtilen karakter kodlaması. Belgede belirtilmediğinde veya bilinmediğinde (örneğin, belge bellekte oluşturulmuşssa) değeri null'dur.
xmlStandalone: XML bildiriminde belirtildiği gibi, belgenin tek bir belgeden oluşup oluşmadığını belirtir. Belgede belirtilmemişse değeri null'dur.
xmlVersion: XML bildiriminde belirtildiği gibi, belgenin XML sürümü. Hiçbir bildirim yoksa ve belge XML'i destekliyorsa değer: "1.0".

Sürüm Bilgisi

Sürüm:	Açıklama
8.0.0	DOMDocument artık DOMParentNode arayüzünü gerçekliyor.
8.0.0	Gerçeklenmemiş olan DOMDocument::renameNode() yöntemi kaldırıldı.

Notlar

Bilginize:
DOM eklentisi UTF-8 kodlama kullanır. Diğer kodlamalarla çalışmak için mb_convert_encoding(), UConverter::transcode() veya iconv() kullanılabilir.

Bilginize:
DOMDocument nesnesi üzerinde json_encode() işlevi kullanılırsa sonuç boş bir nesnenin kodlanması olacaktır.

Showing a quick example of how to use this class, just so that new users can get a quick start without having to figure it all out by themself. ( At the day of posting, this documentation just got added and is lacking examples. )

<?php

// Set the content type to be XML, so that the browser will   recognise it as XML.
header( "content-type: application/xml; charset=ISO-8859-15" );

// "Create" the document.
$xml = new DOMDocument( "1.0", "ISO-8859-15" );

// Create some elements.
$xml_album = $xml->createElement( "Album" );
$xml_track = $xml->createElement( "Track", "The ninth symphony" );

// Set the attributes.
$xml_track->setAttribute( "length", "0:01:15" );
$xml_track->setAttribute( "bitrate", "64kb/s" );
$xml_track->setAttribute( "channels", "2" );

// Create another element, just to show you can add any (realistic to computer) number of sublevels.
$xml_note = $xml->createElement( "Note", "The last symphony composed by Ludwig van Beethoven." );

// Append the whole bunch.
$xml_track->appendChild( $xml_note );
$xml_album->appendChild( $xml_track );

// Repeat the above with some different values..
$xml_track = $xml->createElement( "Track", "Highway Blues" );

$xml_track->setAttribute( "length", "0:01:33" );
$xml_track->setAttribute( "bitrate", "64kb/s" );
$xml_track->setAttribute( "channels", "2" );
$xml_album->appendChild( $xml_track );

$xml->appendChild( $xml_album );

// Parse the XML.
print $xml->saveXML();

?>

Output:
<Album>
  <Track length="0:01:15" bitrate="64kb/s" channels="2">
    The ninth symphony
    <Note>
      The last symphony composed by Ludwig van Beethoven.
    </Note>
  </Track>
  <Track length="0:01:33" bitrate="64kb/s" channels="2">Highway Blues</Track>
</Album>

If you want your PHP->DOM code to run under the .xml extension, you should set your webserver up to run the .xml extension with PHP ( Refer to the installation/configuration configuration for PHP on how to do this ).

Note that this:
<?php
$xml = new DOMDocument( "1.0", "ISO-8859-15" );
$xml_album = $xml->createElement( "Album" );
$xml_track = $xml->createElement( "Track" );
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );
?>

is NOT the same as this:
<?php
// Will NOT work.
$xml = new DOMDocument( "1.0", "ISO-8859-15" );
$xml_album = new DOMElement( "Album" );
$xml_track = new DOMElement( "Track" );
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );
?>

although this will work:
<?php
$xml = new DOMDocument( "1.0", "ISO-8859-15" );
$xml_album = new DOMElement( "Album" );
$xml->appendChild( $xml_album );
?>

After struggling with parsing and modifying partial HTML content for several hours, I came to this solution which does work for me and is relatively simple compared to what else I found online.

This solution fixes unwanted DOCTYPE and html, body tags as well as encoding issues.

<?php

// Assumption: content is utf-8 encoded
$content = "<h1>This is a heading</h1><p>This is a paragraph</p>";

// Load content to a div and specify encoding with a meta tag
$temp_dom = new DOMDocument();
$temp_dom->loadHTML("<meta http-equiv='Content-Type' content='charset=utf-8' /><div>$content</div>");

// As loadHTML() adds a DOCTYPE as well as <html> and <body> tag, let’s create another DOMDocument and import just the nodes we want
$dom = new DOMDocument();
$first_div = $temp_dom->getElementsByTagName('div')[0];
$first_div_node = $dom->importNode($first_div, true);
$dom->appendChild($first_div_node);

// Do whatever you want to do
$dom->getElementsByTagName('h1')[0]->setAttribute('class', 'happy');

// You could also just echo $dom->saveHtml() if you don’t mind the div and whitespace 
echo substr(trim($dom->saveHtml()), 5, -6);

// Outputs: <h1 class="happy">This is a heading</h1><p>This is a paragraph</p>
?>

For those landing here and checking for encoding issue with utf-8 characteres, it's pretty easy to correct it, without adding any additional output tag to your html.

We'll be utilizing: mb_convert_encoding

Thanks to the user who shared: SmartDOMDocument in previous comments, I got the idea of solving it. However I truly wish that he shared the method instead of giving a link.

Anyway coming back to the solution, you can simply use:

<?php

            // checks if the content we're receiving isn't empty, to avoid the warning
            if ( empty( $content ) ) {
                return false;
            }

            // converts all special characters to utf-8
            $content = mb_convert_encoding($content, 'HTML-ENTITIES', 'UTF-8');

            // creating new document
            $doc = new DOMDocument('1.0', 'utf-8');

            //turning off some errors
            libxml_use_internal_errors(true);

            // it loads the content without adding enclosing html/body tags and also the doctype declaration
            $doc->LoadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

            // do whatever you want to do with this code now

?>

I hope it solves the issue for someone! If you need my help or service to fix your code, you can reach me on nabtron.com or contact me at the email mentioned with this comment.

Here's a small function I wrote to get all page links using the DOMDocument which will hopefully be of use to others



<?php

/**

 * @author Jay Gilford

 */

 

/**

 * get_links()

 * 

 * @param string $url

 * @return array

 */

function get_links($url) {

 

    // Create a new DOM Document to hold our webpage structure

    $xml = new DOMDocument();

 

    // Load the url's contents into the DOM

    $xml->loadHTMLFile($url);

 

    // Empty array to hold all links to return

    $links = array();

 

    //Loop through each <a> tag in the dom and add it to the link array

    foreach($xml->getElementsByTagName('a') as $link) {

        $links[] = array('url' => $link->getAttribute('href'), 'text' => $link->nodeValue);

    }

 

    //Return the links

    return $links;

}

For anyone else who has been having issues with formatOuput not working, here is a work-around:



rather than just doing something like:



<?php

$outXML = $xml->saveXML();

?>



force it to reload the XML from scratch, then it will format correctly:



<?php

$outXML = $xml->saveXML();

$xml = new DOMDocument();

$xml->preserveWhiteSpace = false;

$xml->formatOutput = true;

$xml->loadXML($outXML);

$outXML = $xml->saveXML();

For using safely with script nodes when parsing, best option is extending DOMDocument, keeping script tags while DOMDocument process and rearrange them just after saveHTML function is called. Here is my custom class.

<?php 

class SafeDOMDocument extends \DOMDocument
{
    const REGEX_JS            = '#(\s*<!--(\[if[^\n]*>)?\s*(<script.*</script>)+\s*(<!\[endif\])?-->)|(\s*<script.*</script>)#isU';
    const SUBSTITUTION_FORMAT = '<!--<script class="script_%s"></script>-->';
    private $matchedScripts = [];

    public function loadHTML($source, $options = 0)
    {
        $this->formatOutput        = false;
        $this->preserveWhiteSpace  = true;
        $this->validateOnParse     = false;
        $this->strictErrorChecking = false;
        $this->recover             = false;
        $this->resolveExternals    = false;
        $this->substituteEntities  = false;
        $matches = [];
        $success = preg_match_all(self::REGEX_JS, $source, $matches);

        if ($success && !empty($matches)) {
            foreach ($matches[0] as $match) {
                $storedScript = rtrim(ltrim($match, "\n\r\t "), "\n\r\t ");
                $scriptId = md5($storedScript);
                $key = sprintf(self::SUBSTITUTION_FORMAT, $scriptId);
                $source = str_replace($match, $key, $source);
                $this->matchedScripts[$key] = $storedScript;
            }
        }

        return parent::loadHTML($source, $options);
    }

    public function saveHTML(DOMNode $node = null)
    {
        $output = parent::saveHTML($node);

        if (count($this->matchedScripts)) {
            foreach ($this->matchedScripts as $substitution => $originalSnippet) {
                $output = str_replace($substitution, $originalSnippet, $output);
            }
        }

        return $output;
    }
}
?>

A nice and simple node 2 array I wrote, worth a try ;) 



<?php

function getArray($node)

{

    $array = false;



    if ($node->hasAttributes())

    {

        foreach ($node->attributes as $attr)

        {

            $array[$attr->nodeName] = $attr->nodeValue;

        }

    }



    if ($node->hasChildNodes())

    {

        if ($node->childNodes->length == 1)

        {

            $array[$node->firstChild->nodeName] = $node->firstChild->nodeValue;

        }

        else

        {

            foreach ($node->childNodes as $childNode)

            {

                if ($childNode->nodeType != XML_TEXT_NODE)

                {

                    $array[$childNode->nodeName][] = $this->getArray($childNode);

                }

            }

Look out for the following gotcha when loading XML from a string:

<?php
$doc = new \DOMDocument;
$doc->documentURI = $myXmlFilename;
$doc->loadXML($myXmlString);
?>

documentURI is now set to the value of $myXmlFilename, right?

Wrong!

It's set to the current working directory.  If you want to manually set documentURI to something other than the CWD, do so AFTER the call to loadXML().

E.g.:
<?php
$doc = new \DOMDocument;
$doc->loadXML($myXmlString);
$doc->documentURI = $myXmlFilename;
?>

documentURI really is now set to the value of $myXmlFilename.

You may need to save all or part of a DOMDocument as an XHTML-friendly string, something compliant with both XML and HTML 4. Here's the DOMDocument class extended with a saveXHTML method:

<?php

/**
 * XHTML Document
 *
 * Represents an entire XHTML DOM document; serves as the root of the document tree.
 */
class XHTMLDocument extends DOMDocument {

  /**
   * These tags must always self-terminate. Anything else must never self-terminate.
   * 
   * @var array
   */
  public $selfTerminate = array(
      'area','base','basefont','br','col','frame','hr','img','input','link','meta','param'
  );
  
  /**
   * saveXHTML
   *
   * Dumps the internal XML tree back into an XHTML-friendly string.
   *
   * @param DOMNode $node
   *         Use this parameter to output only a specific node rather than the entire document.
   */
  public function saveXHTML(DOMNode $node=null) {
    
    if (!$node) $node = $this->firstChild;
    
    $doc = new DOMDocument('1.0');
    $clone = $doc->importNode($node->cloneNode(false), true);
    $term = in_array(strtolower($clone->nodeName), $this->selfTerminate);
    $inner='';
    
    if (!$term) {
      $clone->appendChild(new DOMText(''));
      if ($node->childNodes) foreach ($node->childNodes as $child) {
        $inner .= $this->saveXHTML($child);
      }
    }
    
    $doc->appendChild($clone);
    $out = $doc->saveXML($clone);
    
    return $term ? substr($out, 0, -2) . ' />' : str_replace('><', ">$inner<", $out);

  }

}

?>

This hasn't been benchmarked, but is probably significantly slower than saveXML or saveHTML and should be used sparingly.

Be careful with formatOutput().

Creating an empty node like this:
createElement('foo','')
instead of
createElement('foo')
will break formatOutput.

This function may help to debug current dom element:

<?php
function dom_dump($obj) {
    if ($classname = get_class($obj)) {
        $retval = "Instance of $classname, node list: \n";
        switch (true) {
            case ($obj instanceof DOMDocument):
                $retval .= "XPath: {$obj->getNodePath()}\n".$obj->saveXML($obj);
                break;
            case ($obj instanceof DOMElement):
                $retval .= "XPath: {$obj->getNodePath()}\n".$obj->ownerDocument->saveXML($obj);
                break;
            case ($obj instanceof DOMAttr):
                $retval .= "XPath: {$obj->getNodePath()}\n".$obj->ownerDocument->saveXML($obj);
                //$retval .= $obj->ownerDocument->saveXML($obj);
                break;
            case ($obj instanceof DOMNodeList):
                for ($i = 0; $i < $obj->length; $i++) {
                    $retval .= "Item #$i, XPath: {$obj->item($i)->getNodePath()}\n".
"{$obj->item($i)->ownerDocument->saveXML($obj->item($i))}\n";
                }
                break;
            default:
                return "Instance of unknown class";
        }
    } else {
        return 'no elements...';
    }
    return htmlspecialchars($retval);
}
?>

Example usage:

<?php
$dom = new DomDocument();
$dom->load('test.xml');
$body = $dom->documentElement->getElementsByTagName('book');
echo '<pre>'.dom_dump($body).'<pre>';
?>

Output:

when you add the new element to formatted XML data through appendChild() method, you would the new element you add is not be formatted(that is not indexed, not line break).  here is my solution (in short load the xml without preserve white space, ), example show as below:
<?php
$doc = new \DOMDocument();
$doc->formatOutput = true;
$doc->preserveWhiteSpace = false;//that is key, default value is true. 
$doc->loadXML($xmlStr);
$doc->appendChild($doc->createElement('php', '666'))
$formattedXMLStr = $doc->saveXML();//DOMDocument wold format the xml str for you
echo $formattedXMlStr;
?>
it take me some time to try it out. hope it save your time.

How to objetify a DomDocument with hierarchy like:
<root>
    <item>
          <prop1>info1</prop1>
          <prop2>info2</prop2>
          <prop3>info3</prop3>
     </item>
    <item>
          <prop1>info1</prop1>
          <prop2>info2</prop2>
          <prop3>info3</prop3>
     </item>
</root>

It's possible to use in object style to retrieve information, as:

<?php
     $theNodeValue = $aitem->prop1;
?>

Here is the code: one Class and 2 functions.

<?php
 class ArrayNode{
       public $nodeName, $nodeValue;
 }

 function getChildNodeElements( $domNode ){
     $nodes = array();
     for( $i=0; $i < $domNode->childNodes->length; $i++){
       $cn = $domNode->childNodes->item($i);
       if( $cn->nodeType == 1){
           $nodes[] = $cn;
           }
     }
    return $nodes;
 }

 function getArrayNodes( $domDoc ){
     $res = array();

       for( $i=0; $i < $domDoc->childNodes->length; $i++){
       $cn = $domDoc->childNodes->item($i);
       # The first is the root tag...
          if( $cn->nodeType == 1){
               # But we want it's childNodes.
                $sub_cn = getChildNodeElements( $cn);
                # Found the tagName:
                $baseItemTagName = $sub_cn[0]->nodeName;
                break;
            }
        }

       $dnl = $domDoc->getElementsByTagName( $baseItemTagName);

       for( $i=0; $i< $dnl->length; $i++){
          $arrayNode = new ArrayNode();

      # Summary
      $arrayNode->nodeName = $dnl->item($i)->nodeName;
      $arrayNode->nodeValue = $dnl->item($i)->nodeValue;

      # Child Nodes
      $cn = $dnl->item($i)->childNodes;
      for( $k=0; $k<$cn->length; $k++){
           if( $cn->item($k)->nodeName == "#text" && trim($cn->item($k)->nodeValue) == "") continue;
           $arrayNode->{$cn->item($k)->nodeName} = $cn->item($k)->nodeValue;
      }

      # Attributes
      $attr = $dnl->item($i)->attributes;
      for( $k=0; $k < $attr->length; $k++){
           if(! is_null($attr)){
            if( $attr->item($k)->nodeName == "#text" && trim($attr->item($k)->nodeValue) == "") continue;
            $arrayNode->{$attr->item($k)->nodeName} = $attr->item($k)->nodeValue;
           }
      }

      $res[] = $arrayNode;

       }

     return $res;
 }
?>

To use it:

<?php

  # First you load a XML in a DomDocument variable.

   $url = "/path/to/yourxmlfile.xml";
   $domSrc = file_get_contents($url);
   $dom = new DomDocument();
   $dom->loadXML( $domSrc );

  # Then, you get the ArrayNodes from the DomDocument.

    $ans = getArrayNodes( $dom );

 
    for( $i=0; $i < count( $ans ) ; $i++){

    $cn =  $ans[ $i];

    $info1 =  $cn->prop1;
    $info2 =  $cn->prop2;
    $info3 =  $cn->prop3;
      
         // ...
 
   }

?>

Easy function for basic output of XML file via DOM parsing

<?php
$dom = new DomDocument();
$dom->load("./file.xml") or die("error");
$start = $dom->documentElement;
fc($start);

function fc($node) {
  $child = $node->childNodes;
  foreach($child as $item) {
    if ($item->nodeType == XML_TEXT_NODE) {
      if (strlen(trim($item->nodeValue))) echo trim($item->nodeValue)."<br/>";
    }
    else if ($item->nodeType == XML_ELEMENT_NODE) fc($item);
  }
}
?>

After seeing many complaints about certain DOMDocument shortcomings, such as bad handling of encodings and always saving HTML fragments with <html>, <head>, and DOCTYPE, I decided that a better solution is needed.

So here it is: SmartDOMDocument. You can find it at http://beerpla.net/projects/smartdomdocument/

Currently, the main highlights are:

- SmartDOMDocument inherits from DOMDocument, so it's very easy to use - just declare an object of type SmartDOMDocument instead of DOMDocument and enjoy the new behavior on top of all existing functionality (see example below).

- saveHTMLExact() - DOMDocument has an extremely badly designed "feature" where if the HTML code you are loading does not contain <html> and <body> tags, it adds them automatically (yup, there are no flags to turn this behavior off).
Thus, when you call $doc->saveHTML(), your newly saved content now has <html><body> and DOCTYPE in it. Not very handy when trying to work with code fragments (XML has a similar problem).
SmartDOMDocument contains a new function called saveHTMLExact() which does exactly what you would want - it saves HTML without adding that extra garbage that DOMDocument does.

- encoding fix - DOMDocument notoriously doesn't handle encoding (at least UTF-8) correctly and garbles the output.
SmartDOMDocument tries to work around this problem by enhancing loadHTML() to deal with encoding correctly. This behavior is transparent to you - just use loadHTML() as you would normally.

- SmartDOMDocument Object As String - you can use a SmartDOMDocument object as a string which will print out its contents.
For example:
<?php
echo "Here is the HTML: $smart_dom_doc";
?>

I'm going to maintain this code and try to fix bugs as they come in.

Enjoy.

A simple function to grab all links in a page. 

    function get_links($url) {

        // Create a new DOM Document to hold our webpage structure 
        $xml = new DOMDocument();

        // Load the url's contents into the DOM 

        $xml->loadHTMLFile($url);

        // Empty array to hold all links to return 
        $links = array();

        //Loop through each <a> tag in the dom and add it to the link array 
        foreach ($xml->getElementsByTagName('a') as $link) {
            $url = $link->getAttribute('href');
            if (!empty($url)) {
                $links[] = $link->getAttribute('href');
            }
        }

        //Return the links 
        return $links;
    }

If you want to use the DOMDocument to create xHTML documents here is a simple class

Note this is designed for creating xHTML documents from scratch but could be easily extended to work with xHTML documents. Also this is for xHTML not XML.

<?php
    class Document
    {
        public $doctype;
        public $head;
        public $title = 'Sensei Ninja';
        public $body;
        private $styles;
        private $metas;
        private $scripts;
        private $document;
        
        
        function __construct (  )
        {
            $this->document = new DOMDocument( );
            $this->head = $this->document->createElement( 'head', ' ' );
            $this->body = $this->document->createElement( 'body', ' ' );
        }
        
        
        public function addStyleSheet ( $url, $media='all' )
        {
            $element = $this->document->createElement( 'link' );
            $element->setAttribute( 'type', 'text/css' );
            $element->setAttribute( 'href', $url );
            $element->setAttribute( 'media', $media );
            $this->styles[] = $element;
        }
        
        
        public function addScript ( $url )
        {
            $element = $this->document->createElement( 'script', ' ' );
            $element->setAttribute( 'type', 'text/javascript' );
            $element->setAttribute( 'src', $url );
            $this->scripts[] = $element;
        }
        
        
        public function addMetaTag ( $name, $content )
        {
            $element = $this->document->createElement( 'meta' );
            $element->setAttribute( 'name', $name );
            $element->setAttribute( 'content', $content );
            $this->metas[] = $element;
        }
        
        
        public function setDescription ( $dec )
        {
            $this->addMetaTag( 'description', $dec );
        }
        
        
        public function setKeywords ( $keywords )
        {
            $this->addMetaTag( 'keywords', $keywords );
        }
        
        public function createElement ( $nodeName, $nodeValue=null )
        {
          return $this->document->createElement( $nodeName, $nodeValue ); 
        }
        
        public function assemble ( )
        {
            // Doctype creation
            $doctype = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML TRANSITIONAL 1.0//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">';
            
            // Create the head element
            $title = $this->document->createElement( 'title', $this->title );
            // Add stylesheets if needed
            if ( is_array( $this->styles ))
                foreach ( $this->styles as $element )
                    $this->head->appendChild( $element );
            // Add scripts if needed
            if(  is_array( $this->scripts ))
                foreach ( $this->scripts as $element )
                    $this->head->appendChild( $element );
            // Add meta tags if needed
            if ( is_array( $this->metas ))
                foreach ( $this->metas as $element )
                    $this->head->appendChild( $element );
            $this->head->appendChild( $title );
            
            // Create the document
            $html = $this->document->createElement( 'html' );
            $html->setAttribute( 'xmlns', 'http://www.w3.org/1999/xhtml' );
            $html->setAttribute( 'xml:lang', 'en' );
            $html->setAttribute( 'lang', 'en' );
            $html->appendChild( $this->head );
            $html->appendChild( $this->body );
            
            
            $this->document->appendChild( $html );
            return $doctype . $this->document->saveXML( );
        }
        
    }
    
?>

Small example

<?php
        $document = new Document( );
    $document->title = 'Hello';
    $document->addStyleSheet( 'StyleSheets/main.css' );
    $div = $document->createElement( 'div' );
    $div->nodeValue = 'Hello, world!';
    $div->setAttribute( 'style', 'color: red;' );
    $document->body->appendChild( $div );
    printf( '%s', $document->assemble( ) );
?>

In this post http://softontherocks.blogspot.com/2014/11/descargar-el-contenido-de-una-url_11.html I found a simple way to get the content of a URL with DOMDocument, loadHTMLFile and saveHTML().

function getURLContent($url){
    $doc = new DOMDocument;
    $doc->preserveWhiteSpace = FALSE;
    @$doc->loadHTMLFile($url);
    return $doc->saveHTML();
}

add a note
