Although I say XML file I actually build and process it in memory. I only write a copy to disk for debugging purposes. The contents of the file (or document) is the same wherever it exists. > also, is there any reason to leverage the validation features of xml while > building a dynamic page? for instance assume data was drawn from a > database to create 1 or more xml files. would it make sense to validate > those new xml files prior to invoking the xslt processor, and optionally > not invoke the transformation process if the xml data is found to be > invalid? This would be overkill. If you are going to build and consume an XML document yourself there is no point in validating it. Remember that XML was originally designed as a format for data interchange, so validation is only necessary when you receive an XML document from a third party. -- Tony Marston http://www.tonymarston.net http://www.radicore.org > thanks, > > -nathan > > On 7/22/07, Tony Marston <[EMAIL PROTECTED]> wrote: >> >> You misunderstand that article.
