effective use of DOM

hey,
IBM developerWorks just came out with an article that recommend how to
process XML with DOM and XPath.  The article is an analysis of many DOM
projects and suggests how to avoid buggy code.
Specifically, given the limitation of DOM this article suggests whenever
possible to use XPath to find nodes and use a library of higher-level
functions.
