DESCRIPTION"XML::XPath::Builder" is a SAX handler for building an XML::XPath tree.
"XML::XPath::Builder" is used by creating a new instance of "XML::XPath::Builder" and providing it as the Handler for a SAX parser. Calling `"parse()"' on the SAX parser will return the root node of the tree built from that parse.
