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)
Ray dot Paseur at Gmail dot com (2012-12-16 00:42:50)
Observed in PHP 5.3.19
JSON implements data types that include NULL, TRUE, FALSE, INT and FLOAT. It appears that these types are not implemented in SimpleXML. The JSON_Decode() function returns an object instance of stdClass which supports these data types. However objects of SimpleXMLElement do not.
The effect of this difference is that you cannot necessarily use a conversion of a stdClass object into a SimpleXMLElement, and so the AsXML() method is out of play.

Here is an example of an easy mapping between xml and classes defined by user.
<?php
class XmlClass extends SimpleXMLElement
{
/**
* Returns this object as an instance of the given class.
*/
public function asInstanceOf($class_name)
{
// should check that class_name is valid
return simplexml_import_dom(dom_import_simplexml($this), $class_name);
}
public function __call($name, array $arguments)
{
echo "magic __call called for method $name on instance of ".get_class()."\n";
// class could be mapped according $this->getName()
$class_name = 'Test';
$instance = $this->asInstanceOf($class_name);
return call_user_func_array(array($instance, $name), $arguments);
}
}
class Test extends XmlClass
{
public function setValue($string)
{
$this->{0} = $string;
}
}
$xml = new XmlClass('<example><test/></example>');
$test = $xml->test->asInstanceOf('Test');
echo get_class($xml->test), "\n";
echo get_class($test), "\n";
$test->setValue('value set directly by instance of Test');
echo (string)$xml->test, "\n";
echo (string)$test, "\n";
$xml->test->setValue('value set by instance of XmlClass and magic __call');
echo (string)$xml->test, "\n";
echo (string)$test, "\n";
?>
XmlClass
Test
value set directly by instance of Test
value set directly by instance of Test
magic __call called for method setValue on instance of XmlClass
value set by instance of XmlClass and magic __call
value set by instance of XmlClass and magic __call

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
);
}

In many situations, the methods of supporting CDATA in comments above may inappropriate (especially if an external library is using simplexml).
Instead, you may simply cast CDATA elements to a string, such as:
print (string)$xml->cdataelement or (string)$xml->{'cdataelement'}
In my case, it eliminated the need for me to edit an external library file every time an upgrade for the file was released.

FAIL! This function works better than the one I posted below:
<?php
function toArray($xml) {
$array = json_decode(json_encode($xml), TRUE);
foreach ( array_slice($array, 0) as $key => $value ) {
if ( empty($value) ) $array[$key] = NULL;
elseif ( is_array($value) ) $array[$key] = toArray($value);
}
return $array;
}
thedoc8786 at gmail dot com (2012-03-23 16:19:04)
I know it is over-done, but the following is a super-short example of a XML to Array conversion function (recursive):
<?php
function toArray(SimpleXMLElement $xml) {
$array = (array)$xml;
foreach ( array_slice($array, 0) as $key => $value ) {
if ( $value instanceof SimpleXMLElement ) {
$array[$key] = empty($value) ? NULL : toArray($value);
}
}
return $array;
}

$xml->$name=$value;
} else {
$xml->$name=null;
$this->iteratechildren($value,$xml->$name);
}
}
}
function toXml($object) {
$this->iteratechildren($object,$this->xmlResult);
return $this->xmlResult->asXML();
}
}
//----test object----
$ob->field1=10;
$ob->field2->field21="textA";
$ob->field2->field22="textB";

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

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();
}
?>

An easer way to get the text node if you can't access to [0] property of the simpleXMLElement is to use the sprintf function.
As gwhitescarver at yahoo dot com said, in some version of php 5 it is hard to access to text node of an element, but when you print the element, the [0] property is automaticaly returned.
Like if you echo() the element, the text node is return.
The sprintf function do the same:
<?php
$a = array();
foreach ($xml->children() as $child) {
$a[$child->getName()] = sprintf("%s", $child);
}
?>

Here's a function I came up with to convert an associative array to XML. Works for multidimensional arrays as well.
<?php
function assocArrayToXML($root_element_name,$ar)
{
$xml = new SimpleXMLElement("<?xml version=\"1.0\"?><{$root_element_name}></{$root_element_name}>");
$f = create_function('$f,$c,$a','
foreach($a as $k=>$v) {
if(is_array($v)) {
$ch=$c->addChild($k);
$f($f,$ch,$v);
} else {
$c->addChild($k,$v);
}
}');
$f($f,$xml,$ar);
return $xml->asXML();
}
?>
philipp at strazny dot com (2010-11-23 17:33:51)
Here's a quick way to dump the nodeValues from SimpleXML into an array using the path to each nodeValue as key. The paths are compatible with e.g. DOMXPath. I use this when I need to update values externally (i.e. in code that doesn't know about the underlying xml). Then I use DOMXPath to find the node containing the original value and update it.
<?php
function XMLToArrayFlat($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.
kristof at viewranger dot com (2010-11-18 05:14:40)
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.

This is very simple way to convert all applicable objects into associative array. This works with not only SimpleXML but any kind of object. The input can be either array or object. This function also takes an options parameter as array of indices to be excluded in the return array. And keep in mind, this returns only the array of non-static and accessible variables of the object since using the function get_object_vars().
<?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
$arrData = array();
// if input is object, convert into array
if (is_object($arrObjData)) {
$arrObjData = get_object_vars($arrObjData);
}
if (is_array($arrObjData)) {
foreach ($arrObjData as $index => $value) {
if (is_object($value) || is_array($value)) {
$value = objectsIntoArray($value, $arrSkipIndices); // recursive call
}
if (in_array($index, $arrSkipIndices)) {
continue;
}
$arrData[$index] = $value;
}
}
return $arrData;
}
?>
Usage:
<?php
$xmlUrl = "feed.xml"; // XML feed file/URL
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);
print_r($arrXml);
?>

If you decide to include a hyphen or a dash in the name of your attribute things get a bit interesting. The code has to be adjusted since the name of a class method cannot contain "-". To make it work, the attribute name has to include braces and single quotes (e.g. "{'name'}").

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

I tested all the scripts ive found on this page but none of them wasnt working.
ive made an new script that will work and wont get any memory errors with big xml feeds
<?php
print "<pre>";
$root = simplexml_load_string($XML_URL);
$data = get_object_vars($root);
$producten = array();
foreach ($data['product'] as $keys => $values) {
$producten['product'][$keys] = get_object_vars($data['product']);
foreach ($values as $key => $value) {
$value = str_replace("\r\n", '<br />', $value);
$value = str_replace("\r", '<br />', $value);
$value = str_replace("\n", '<br />', $value);
$producten['product'][$keys][$key] = $value;
}
}
print_R($producten);
print "</pre>";

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;
$list_all_api_name = array();
$i = 0;
foreach ($all_api->children() as $funcky_function)
{
$string_tmp = (string )$funcky_function->function;
$list_all_api_name[$i++] = $putain;
}
?>

There are issues with most examples of converting a simplexml object into an array recursively. The situation that fails is when you have a value for an element and attributes. For example:
<results found="yes">
<warehouse>
<name>WH3</name>
<phone>2-1121</phone>
</warehouse>
<items count="3">
<item id="E1120" bin="AA21">Desk</item>
<item id="E1121" bin="FG03">Chair</item>
<item id="E1122" bin="CD00">Table</item>
</items>
</results>
If you :
<?php
$obj = simplexml_load_string($xml);
print_r($obj);
?>
You will get:
(
[@attributes] => Array
(
[found] => yes
)
[warehouse] => SimpleXMLElement Object
(
[name] => WH3
[phone] => 2-1121
)
[items] => SimpleXMLElement Object
(
[@attributes] => Array
(
[count] => 3
)
[item] => Array
(
[0] => Desk
[1] => Chair
[2] => Table
)
)
)
Where is the rest of the data for the items? If you were to traverse recursively through the object the item information is in fact there. The problem is how to represent an element as an array that has a value and attributes. Most of the solution's just ignore the attributes.
print_r, var_dump, and get_object_vars ignore the attributes in this special case from what I've found.
Here is a simple function to convert the object into an array but it still fails to deal with the attributes.
<?php
function ToArray ( $data )
{
if (is_object($data)) $data = get_object_vars($data);
return (is_array($data)) ? array_map(__FUNCTION__,$data) : $data;
}
?>
So why even bother trying to convert the object to an array? Simply because of serialization for caching the object.
One solution would be to create an index called "value" and assign that the element's value. This way the attributes could coexist.

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;
}

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;
?>

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]
?>

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

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;

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);

Optimizing aalaap at gmail dot com's php
<?php
function is_rss($feedxml) {
@$feed = simplexml_load_string($feedxml);
return ($feed->channel->item)?true:false;
}
function is_atom($feedxml) {
@$feed = new SimpleXMLElement($feedxml);
($feed->entry):true:false;
}
?>
aalaap at gmail dot com (2008-06-30 06:58:55)
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.
