Christian, The application you're describing is called the XPath Visualiser and has been publicly announced 3 months ago. You can download it at http://www.vbxml.com/xpathvisualizer Besides its major function to hilight in the source xml documents all nodes satisfying a given XPath expression and help the user navigate through them, the XPath Visualiser displays also the results of scalar XPath expressions, remembers all the XPath expressions entered for a particular file and re-instates the appropriate list of expressions when another XML file is re-loaded. The collapsible/expandable syntax-coloured outline view also displays in a special way "container nodes" that are collapsed and "hide" some occurrence(s) of the result node-set elements. And there are at least three new major features still to come in the nearest future... You can immediately find the answers to your questions in the source code of this tool, as many other developers have already done. During these three months it has gained some popularity and now some major sites including www.w3c.org, www.xslt.com, www.xmlinfo.com, www.xmlsoftware.com (and of course www.vbxml.com :o)) ) have links and brief descriptions of the XPath Visualiser. I'd greatly appreciate receiving any comments reflecting your experience with the XPath Visualiser. Do enjoy, Dimitre Novatchev. P.S. Your original question can be stated more precisely in the following way: What is the XPath expression that evaluates whether the current node belongs to a given node-set. Answer: <xsl:if test="count(. | $SelectedNodes) = count($SelectedNodes) "> ---------------------------------- ------------------------------ Christian Nentwich wrote: Dear all, we have produced a simple stylesheet that transforms an XML document into a simple HTML document, with tags in colours, etc. (like the IE5 default stylesheet). We also have a parameter containing an xpath expression that can be applied to the XML file. We want to highlight nodes in the translated HTML page that match the xpath expression, e.g. the stylesheet looks like this: <xsl:param name="xpath"/> .... <xsl:template match="node()"> .. </xsl:template> This problem seems to appear in different forms in the FAQ but I couldn't find a proper solution. I know that <xsl:template match="$xpath">..</..> won't work. Similarly, <xsl:template match="node()"> <xsl:choose> <xsl:when test="somefunc(.,$xpath)"/> </xsl:choose> </xsl:template> to check whether the current node matches the xpath, since there is no such function. Has anyone had a similar problem? Thanks, Christian __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.
