=head1 NAME

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

=head1 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);

=head1 DESCRIPTION

C<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
`C<at_path()>'.  C<XML::Grove::Path> is B<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 `C<#any>' object type matches any type of object, it is
essentially an index into the contents of the parent object.

The `C<#text>' object type treats text objects as if they are not
normalized.  Two consecutive text objects are seperate text objects.
