In the blog, I wrote some helper methods to locate XML elements and return their values in a less verbose way.

You may also view this list in XML, DAML and OWL formats or using Spectacle.

A wishlist of desired tools is also being maintained.

This proved to be one of my most popular blog entries to date.

However, one reader commented that it would be nice to add helper methods to easily create or modify XML, not just parse it. I've added two new helper methods to the code I presented last time: The code works by first locating the specified node within the list of nodes provided.

XPath x Path = XPath Instance()XPath(); Node start Date Node = (Node) x Path.compile("/data/startdate").evaluate(doc, XPath Constants.
