Ben and all, sure; in most cases, the transformation is dealing with the structure of the source-doc: this is what XSLT is designed for; in most of those cases, context-sensitive operations/expressions/functions are the most elegant and most appropriate. No doubt. But in some exceptional cases, context-independant operations are appropriate, to save code. If I have three elements "ruler", and want to output one ruler with a hundred lines for each I could: 1) code the ruler as a template, and output one for each element "ruler" - makes 100 line-elements to code or 2) generate the ruler with a loop, and run that loop for each element "ruler" - makes 1 line-element to code The case in my email was just a basic example, where position() would have been appropriate. I just couldn't figure out how to create a context-independant loop; it's good to know that XSLT is capable of doing this. Many thanks to all for your emails; this is my first day in this list and I really feel at home; this list is *awesome* !
