Storing SimpleXMLElement values in $_SESSION does not work. Saving the results as an object or individual elements of the object will result in the dreaded "Warning: session_start() [function.session-start]: Node no longer exists" error.
For example, this does not work:
$xml = new SimpleXMLElement($page);
$country = $xml->Response->Placemark->AddressDetails->Country->CountryNameCode;
$_SESSION['country'] = $country;
This will work:
$_SESSION['country'] = (string) $country;

while using simple xml and get double or float int value from xml object for using math operations (+ * - / ) some errors happens on the operation, this is because of simple xml returns everythings to objects.
exmple;
<?php
$name = "somestring";
$size = 11.45;
$xml = '
<xml>
<name>somestring</name>
<size>11.45</size>
</xml>';
$xmlget = simplexml_load_string($xml)
echo $xml->size*2; // 20 its false
// ($xml->size is an object (int)11 and (45) )
// this is true
echo $size*2; // 22.90
echo (float)$size*2; // 22.90

Here is a recursive function that will convert a given SimpleXMLElement object into an array, preserving namespaces and attributes.
<?php
function xmlObjToArr($obj) {
$namespace = $obj->getDocNamespaces(true);
$namespace[NULL] = NULL;
$children = array();
$attributes = array();
$name = strtolower((string)$obj->getName());
$text = trim((string)$obj);
if( strlen($text) <= 0 ) {
$text = NULL;
}
// get info for all namespaces
if(is_object($obj)) {
foreach( $namespace as $ns=>$nsUrl ) {
// atributes
$objAttributes = $obj->attributes($ns, true);
foreach( $objAttributes as $attributeName => $attributeValue ) {
$attribName = strtolower(trim((string)$attributeName));
$attribVal = trim((string)$attributeValue);
if (!empty($ns)) {
$attribName = $ns . ':' . $attribName;
}
$attributes[$attribName] = $attribVal;
}
// children
$objChildren = $obj->children($ns, true);
foreach( $objChildren as $childName=>$child ) {
$childName = strtolower((string)$childName);
if( !empty($ns) ) {
$childName = $ns.':'.$childName;
}
$children[$childName][] = xmlObjToArr($child);
}
}
}
return array(
'name'=>$name,
'text'=>$text,
'attributes'=>$attributes,
'children'=>$children
);
}

If you tried to load an XML file with this, but the CDATA parts were not loaded for some reason, is because you should do it this way:
$xml = simplexml_load_file($this->filename, 'SimpleXMLElement', LIBXML_NOCDATA);
This converts CDATA to String in the returning object.

To add to what others have said, you can't directly put a $_GET or $_POST value into a variable then into an attribute using SimpleXML. You must first convert it to an integer.
This will NOT work
<?php
$page_id = $_GET['id'];
echo $xml->page[$page_id]
?>
You will get something like:
Notice: Trying to get property of non-object in /Applications/MAMP/htdocs/mysite/index.php on line 10
However, this WILL work and is much simpler then using (string) or other methods.
<?php
$page_id = intval($_GET['id']);
echo $xml->page[$page_id]
?>

The BIGGEST differece between an XML and a PHP array is that in an XML file, the name of elements can be the same even if they are siblings, eg. "<pa><ch /><ch /><ch /></pa>", while in an PHP array, the key of which must be different.
I think the array structure developed by svdmeer can fit for XML, and fits well.
here is an example array converted from an xml file:
array(
"@tag"=>"name",
"@attr"=>array(
"id"=>"1","class"=>"2")
"@text"=>"some text",
)
or if it has childrens, that can be:
array(
"@tag"=>"name",
"@attr"=>array(
"id"=>"1","class"=>"2")
"@items"=>array(
0=>array(
"@tag"=>"name","@text"=>"some text"
)
)
Also, I wrote a function that can change that array back to XML.
<?php
function array2XML($arr,$root) {
$xml = new SimpleXMLElement("<?xml version=\"1.0\" encoding=\"utf-8\" ?><{$root}></{$root}>");
$f = create_function('$f,$c,$a','
foreach($a as $v) {
if(isset($v["@text"])) {
$ch = $c->addChild($v["@tag"],$v["@text"]);
} else {
$ch = $c->addChild($v["@tag"]);
if(isset($v["@items"])) {
$f($f,$ch,$v["@items"]);
}
}
if(isset($v["@attr"])) {
foreach($v["@attr"] as $attr => $val) {
$ch->addAttribute($attr,$val);
}
}
}');
$f($f,$xml,$arr);
return $xml->asXML();
}
?>

Simple means simple. If you know the structure and just want the value of a tag:
<?php
$xml = simplexml_load_file($xmlfile);
print $xml->City->Street->Address->HouseColor;
?>
Warning, numbers can come out as strings, empty elements like <HouseColor></HouseColor> come out as array(0)

Here's a quick way to dump the nodeValues from SimpleXML into an array using the path to each nodeValue as key. The paths are compatible with e.g. DOMXPath. I use this when I need to update values externally (i.e. in code that doesn't know about the underlying xml). Then I use DOMXPath to find the node containing the original value and update it.
<?php
function XMLToArrayFlat($xml, &$return, $path='', $root=false)
{
$children = array();
if ($xml instanceof SimpleXMLElement) {
$children = $xml->children();
if ($root){ // we're at root
$path .= '/'.$xml->getName();
}
}
if ( count($children) == 0 ){
$return[$path] = (string)$xml;
return;
}
$seen=array();
foreach ($children as $child => $value) {
$childname = ($child instanceof SimpleXMLElement)?$child->getName():$child;
if ( !isset($seen[$childname])){
$seen[$childname]=0;
}
$seen[$childname]++;
XMLToArrayFlat($value, $return, $path.'/'.$child.'['.$seen[$childname].']');
}
}
?>
Use like this:
<?php
$xml = simplexml_load_string(...some xml string...);
$xmlarray = array(); // this will hold the flattened data
XMLToArrayFlat($xml, $xmlarray, '', true);
?>
You can also pull multiple files in one array:
<?php
foreach($files as $file){
$xml = simplexml_load_file($file);
XMLToArrayFlat($xml, $xmlarray, $file.':', true);
}
?>
The respective filename/path is thus prefixed to each key.

Here are two quick and dirty functions that use SimpleXML to detect if a feed xml is RSS or ATOM:
<?php
function is_rss($feedxml) {
@$feed = new SimpleXMLElement($feedxml);
if ($feed->channel->item) {
return true;
} else {
return false;
}
}
function is_atom($feedxml) {
@$feed = new SimpleXMLElement($feedxml);
if ($feed->entry) {
return true;
} else {
return false;
}
}
?>
The functions take in the full text feed (retrieved via cURL, for example) and return a true or a false based on the result.

I had a problem with simplexml reading nodes from an xml file. It always return an SimpleXML-Object but not the text inside the node.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<Test>
<Id>123</Id>
</Test>
Reading this xml into a variable called $xml and then doing the following
<?php
$myId = $xml->Id;
?>
Did not return 123 in $myId, but instead I got a SimpleXMLElement Object.
The solution is simple, when you know it. Use explicit string conversion.
<?php
$myId = (string)$xml->Id;
?>

$ch=$c->addChild($k);
$f($f,$ch,$v);
} else {
$c->addChild($k,$v);
}
}');
$f($f,$xml,$ar);
return $xml->asXML();
}

None of the XML2Array functions that I found satisfied me completely; Their results did not always fit the project I was working on, and I found none that would account for repeating XML elements (such as
<fields><field/><field/><field/></fields>)
So I rolled out my own; hope it helps someone.
<?php
/**
* Converts a simpleXML element into an array. Preserves attributes.<br/>
* You can choose to get your elements either flattened, or stored in a custom
* index that you define.<br/>
* For example, for a given element
* <code>
* <field name="someName" type="someType"/>
* </code>
* <br>
* if you choose to flatten attributes, you would get:
* <code>
* $array['field']['name'] = 'someName';
* $array['field']['type'] = 'someType';
* </code>
* If you choose not to flatten, you get:
* <code>
* $array['field']['@attributes']['name'] = 'someName';
* </code>
* <br>__________________________________________________________<br>
* Repeating fields are stored in indexed arrays. so for a markup such as:
* <code>
* <parent>
* <child>a</child>
* <child>b</child>
* <child>c</child>
* ...
* </code>
* you array would be:
* <code>
* $array['parent']['child'][0] = 'a';
* $array['parent']['child'][1] = 'b';
* ...And so on.
* </code>
* @param simpleXMLElement $xml the XML to convert
* @param boolean|string $attributesKey if you pass TRUE, all values will be
* stored under an '@attributes' index.
* Note that you can also pass a string
* to change the default index.<br/>
* defaults to null.
* @param boolean|string $childrenKey if you pass TRUE, all values will be
* stored under an '@children' index.
* Note that you can also pass a string
* to change the default index.<br/>
* defaults to null.
* @param boolean|string $valueKey if you pass TRUE, all values will be

Moving some code from a PHP 5.2.6 / Windows environment to a 5.2.0 / Linux environment, I somehow lost access to a plain text node within a SimpleXML Object. On a var_dump of $xml_node, a [0] element was shown as the string '12'. However, $xml_node[0] was evaluating NULL in 5.2.0. You can see below the code change I made, pulling my data out of the raw XML with a regular expression. Hope this is useful to someone.
//In some versions of PHP it seems we cannot access the [0] element of a SimpleXML Object. Doesn't work in 5.2.0:
//$count = $xml_node[0];
//grab the raw XML:
$count = ($xml_node->asXML());
//pull out the number between the closing and opening brace of the xml:
$count = preg_replace('/.*>(\d*)<.*/', '$1', $count);

(string)$key => (string)$val

Addition to QLeap's post:
SimpleXML will return a reference to an object containing the node value and you can't use references in session variables as there is no feasible way to restore a reference to another variable.
This won't work too:
$val=$this->xml->node->attributes()->name;
echo $array[$val]; // will cause a warning because of the wrong index type.
You have to convert/cast to a String first:
echo $array[(string)$val];
This will work as expected, because converting will call the __toString() method. Therefor echo works too:
echo $val; // will display the name

I know it is over-done, but the following is a super-short example of a XML to Array conversion function (recursive):

$array = (array)$xml;
foreach ( array_slice($array, 0) as $key => $value ) {
if ( $value instanceof SimpleXMLElement ) {
$array[$key] = empty($value) ? NULL : toArray($value);
}
}
return $array;

if for some reasons you need the string value instead of the simpleXML Object you can cast the return value as a string.
exemple:
<?php
$all_api_call = simplexml_load_file($url);
$all_api = array();
$all_api = $all_api_call->result;

XML data values should not contain "&" and that need to be replaced by html-entity "&"
You can use this code to replace lonely "&" to "&":
<?php
$sText = preg_replace('#&(?![a-z]{1,6};)#i', '&', $sText);
?>
This will replace just "&" into "&" but dont touches other html-entities like " ", "<" etc and, of course, "&".
P.S. In regexp max length is 6 becouse I found that is the maximum length of possible html entity using this code:
<?php
max(array_map('strlen', array_values(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES | ENT_HTML5)))) - 2
?>
minus two is for first "&" and last ";" in an any html entity.

I had to do the following to catch the fact that my simplexml_load_string call was not working right (it was returning empty objects).
$statistik = simplexml_load_string($record,"SimpleXMLElement",LIBXML_NSCLEAN,$ns,TRUE);
if (($statistik === FALSE) or ($statistik === NULL) or empty($statistik))
{
echo "$ctr) STATISTIK ERROR---\n";
var_dump($statistik);
echo "\n\n";
echo "Failed loading XML\n";
foreach(libxml_get_errors() as $error)
{
echo "\n", $error->message;
}
die();
}
before I put the check for "empty()" I was not catching the error.

Here is a very robust SimpleXML parser. Can be used to load files, strings, or DOM into SimpleXML, or can be used to perform the reverse when handed SimpleXML.

Working fix for the infamous SimpleXML + memcache bug.
Improves code at http://tinyurl.com/bmoon-simplexml to actually work for arbitrary-depth structures. (Because neither the function nor the json_decode(json_encode($obj)) hack listed there worked for me.)
There's probably some superfluous code in here that could be improved on -- but it works!
<?php
# convert a structure that may include objects to a pure
# array-based structure (that can be stored in memcache)
# ... includes support for simplexml!
# (nb: may have problems with infinite recursive structs)
function enforce_array($obj) {
$array = (array)$obj;
if(empty($array)) {
$array = '';
}
else {
foreach($array as $key=>$value) {
if(!is_scalar($value)) {
if(is_a($value,'SimpleXMLElement')) {
$tmp = memcache_objects_to_array($value);
if(!is_array($tmp)) {
$tmp = ''.$value;
}
$array[$key] = $tmp;
}
else {
$array[$key] = enforce_array($value);
}
}
else {
$array[$key] = $value;
}
}
}
return $array;
}
?>

XML to Array in a single line:
$array = (array) simplexml_load_string($xml);
Enjoy!
