A novice probably isn't going to know what the difference between a function and a node test is. --------- Yes, and I know you know. :-) Of course, in a public forum, one writes for a public audience, and there are plenty of novices around who might benefit from seeing it confirmed that no, those two things aren't at all the same, notwithstanding appearances. A lot of learning goes on around here just from people's watching over each other's shoulders (to say nothing of experts pretending to be novices). I was just hoping (and worth wasting 30 seconds trying) that Maybe in some magic fairyland XSLT would *evaluate* the match="ELEM/string()" and determine that indeed that evaluated to a non-empty string and decide to run the template... Especially when running into the tidbit in the specs that match expressions are a 'subset of XPath expressions' ... so hey, toss a little pixie dust and you never know what comes out ... It would be nice if it worked ... Indeed, and your being willing to conduct such experiments and draw conclusions from them is one of the reasons you're never a novice for long. match="ELEM[string()]" would work not too differently from what you're thinking. It matches when ELEM/string() returns a Boolean true(), i.e. when ELEM's string value is not "". Of course, it matches the ELEM not the text inside it. As to the question at hand, I'm still not sure we know why your template matching "ELEM/text()" was matching more than once inside a given ELEM, whether because of something about your tree, or the presence of a comment or PI or other interference. But I'm not sure you care any more: maybe your actual question has been asked and answered.
