PHP 5 SimpleXML functions

PHP 5SimpleXML function Introduction to PHP SimpleXML

The SimpleXML extension provides a simple way to get the name and text of an XML element, as long as you know the layout of the XML document.

SimpleXML transforms an XML document into a SimpleXMLElement object.

This object can be processed like any other object through the normal property selector and array iterators.

tip: compared to DOM or Expat parsers, SimpleXML can read text data in an element with just a few lines of code.

Installation

The SimpleXML extension requires PHP 5 support.

Since PHP 5, the SimpleXML function is part of the PHP core. These functions can be used without installation.
