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)

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();
}

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
);

dynamic sql in php using xml:

obviously, this example can be improved [in your own code.]

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

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;

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.

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]
?>

I rewrite the function to convert xml object to array because my case is more simple:
function xmlObjToArr($obj) {
$array = [];
foreach($obj as $item){
$row = [];
foreach($item as $key => $val){
$col = array(
(string)$key => (string)$val
);
array_push($row,$col);
}
array_push($array,$row);
}
return $array;
}

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.

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 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;
}

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
* stored under an '@values' index. Note
* that you can also pass a string to
* change the default index.<br/>
* defaults to null.

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

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;
}

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;
}
?>

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);

$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.

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.
<?php

* be processed by the calling application. This accepts xml strings,
* files, and DOM objects. It can also perform the reverse, converting

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

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 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.
