Example:

<?xml version="1.0" encoding="ISO-8859-1"?>
<programme> 
  <title>Billy Bushwaka</title> 
  <episodeNumber>2</episodeNumber> 
  <description>Billy Bushwaka entertains</description> 
  <url>play.swf</url> 
</programme> 

First of all, always name your PHP variables after the node they represent.

// the root node is ie <programme/>
$programme = simplexml_load_file("local.xml");

Access to children (nodes) as if they were object properties.

echo $programme->title;

If there are multiple children using the same name, you can specify their 0-based position

// first <title/> child
echo $programme->title[0];

// create or change the value of the second <title/> child
$programme->title[1] = 'Second title';

Access to attributes as if they were array keys

// <mynode attr="attribute value" />
echo $mynode['attr'];

XPath always returns an array.

Quellcode der xml Datei ausgeben

echo $simplexml->asXML();

XML Daten von URL holen

$xml = file_get_contents($url);
$data = new SimpleXMLElement($xml);
