Hi Joe, > Is there a test for finding the position of the first tag that > contains data? The example would be as follows: > > <root> > <tag1/> > <tag1/> > <tag1/> > <tag1>This one has data</tag> > <tag1>This one has data</tag> > <tag1>This one has data</tag> > </root> > > So I would like position 4 returned. Thank you (That isn't well-formed -- you have 'tag1' start tags and 'tag' end tags.) You can find all the 'tag' elements that contain some text with: tag[string()] You can find the first such 'tag' element with: tag[string()][1] To get its position, you could count how many preceding sibling 'tag' elements it has, and add one (to get the normal 1-based counting scheme): count( tag[string()][1]/preceding-sibling::tag ) + 1 Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
