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 <B>notB> XPath, but it should
become obsolete when an XPath implementation is available.
Paths are like URLs
The path segments can be element names or object types, the objects
types are named using:
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
normalized. Two consecutive text objects are seperate text objects.
