Subject: Re: [xsl] XPath condition supplied as a parameter From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 23 Oct 2002 16:42:39 +0100 |
your condition param is (most likely) a string so select="count(child::*[name()=$data_tag][$data_condition])"/> is legal but [$data_condition] is true just if the supplied string has non zero length, which may not be your desired meaning. In common with most languages, xslt does not have expression valued variables. Some systems have an xx:evaluate extension function to evaluate a string as an xpath expression or in simple cases you can do as in your firs filter [name()=$data_tag] and just have teh expression parameterised by the string which you pass in as a parameter.
