This document provides an overview of the major XML extensions introduced in PHP 5, including DOM, SAX, SimpleXML, XPath, and XSLT. It describes each extension, provides basic examples of how to use them, and notes how they work with XML documents and transform data. The extensions allow PHP 5 to efficiently process XML data while complying with W3C specifications and working together through a standardized XML library.
