The XML_XPath PEAR Class allows easy manipulation, maneuvering, and querying of a domxml tree using both xpath queries and DOM walk functions. It uses an internal pointer for all methods on which the action is performed. Results from an xpath query are returned as an XML_XPath_Result object, which contains all the DOM functions from the main object. This class tries to stay as close as possible to the DOM Recommendation. It is important to note that this is only an interface for the PHP domxml library. It depends on that library available (--with-dom) and hence requires PHP 4.2.1. This class is useful if you are looking for a fast implementation to XML documents.
