Описание скрипта Class::XPath

This module adds XPath-style matching to your object trees. This means that you can find nodes using an XPath-esque query with match() from anywhere in the tree. Also, the xpath() method returns a unique path to a given node which can be used as an identifier.
To use this module you must already have an OO implementation of a tree. The tree must be a true tree - all nodes have a single parent and the tree must have a single root node. Also, the order of children within a node must be stable.
