NAME
       XML::Grove::Path - return the object at a path

SYNOPSIS
	use XML::Grove::Path;

	# Using at_path method on XML::Grove::Document or XML::Grove::Element:
	$xml_obj = $grove_object->at_path("/some/path");

	# Using an XML::Grove::Path instance:
	$pather = XML::Grove::Path->new();
	$xml_obj = $pather->at_path($grove_object);

DESCRIPTION
       "XML::Grove::Path" returns XML objects located at paths.	 Paths are
       strings of element names or XML object types seperated by slash ("/")
       characters.  Paths must always start at the grove object passed to
       ‘"at_path()"’.  "XML::Grove::Path" is not XPath, but it should become
       obsolete when an XPath implementation is available.

       Paths are like URLs

	   /html/body/ul/li[4]
	   /html/body/#pi[2]

       The path segments can be element names or object types, the objects
       types are named using:

	   #element
	   #pi
	   #comment
	   #text
	   #cdata
	   #any

       The ‘"#any"’ object type matches any type of object, it is essentially
       an index into the contents of the parent object.

       The ‘"#text"’ object type treats text objects as if they are not nor-
       malized.	 Two consecutive text objects are seperate text objects.
