Xpath support gives you a very much more productive way of navigating and querying the XML document compared to "pure" DOM, eg the DOM getAttribute() and getElementsByTagName() methods and the childNodes property for element / attribute operations; and the DOM normalize() method and Text interface for text values. MSXML already had workrounds for these areas, but these were experimental and used now-outdated proto-standards. The advantage to using XPath is that you will be using the same powerful and well-reviewed standard as other useful XML tools such as XSLT or the Schematron. > > I am currently processing the XML Document with no intentions to display > the information.

(In fact I have found XSLT very useful for B2B work, you may well want to look at it for your translations.) xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
