XML Processing with Python

12.8. Node Lists

Pyxie provides a collection of functions for the creation and processing of lists of nodes. The Descendants method creates a Python list of all the nodes beneath the active position in an xTree. The following program creates a list of descendants of the root node and uses it to print the data content of an XML document backwards.
