The PEAR::XML_XPath class provided an XPath/DOM XML manipulation,
maneuvering and
query interface.
The class allows for 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 dom/xpath query
are returned
as an XPath_Result object, which contains an internal array of DOM nodes
and which extends
the common DOM class and hence contains all the DOM functions from the
main object to run
on each of the elements in the internal array.  This class tries to hold
as close as possible       to the DOM Recommendation.  You MUST have the
domxml extension to use this class.
The XML_XPath class was inspired by a class maintained by Nigel Swinson
called phpxpath.
The phpxpath class does not rely on PHP xmldom functions and is therefore
a sibling to
this class: http://sourceforge.net/projects/phpxpath
