The SimpleXML extension provides is a simple way of getting an XML element's
name and text, if you
know the XML document's layout.
SimpleXML converts an XML document into a SimpleXMLElement object.
This object can then be processed, like any other object, with normal property selectors and array iterators.
Tip: Compared to DOM or the Expat parser, SimpleXML just takes a few lines of code to read text data from an element.
As of PHP 5, the SimpleXML functions are part of the PHP core. No installation is required to use these functions.
