XML::Grove::Path - return the object at a path
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);
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
normalized. Two consecutive text objects are seperate text objects.
