Subject: [xsl] Xpath expression with condition sought... From: Peter Mabley <p7777m@xxxxxxxxxxx> Date: Tue, 9 Dec 2003 21:07:20 +0000 (GMT) |
I have XML like: <outer> ..... <a>someArbitaryText</a> ..... <b>alsoSomeArbitaryText</b> ..... <c>likewise</c> ...... <d>likewise</d> </outer> I'm looking for a single Xpath ___expression which evaulates to the text at <c> if the text at <a> matches the text at <b>, otherwise to the text at <d>. I'm using Xalan. And yes, I know I could do it in stages in XSLT but I need a SINGLE XPath ___expression. (Why?: because my transform is driven by an XML configuration file defining the XPaths of the items of interest in the source document. My XSLT reads the XPath __expression from the configuration file, and evaluates it as an XPath using xalan:evaluate(). In this particular case the location of the item to be used depends on whether 2 other elements have the same text values.) I can do it this way: //c|//d[position()=2-number(//a=//b)] but this, I believe (correct me if I'm wrong) assumes c & d appear in this order. Is there a way which is independent of the order of c and d in the source document (whilst being a single Xpath _expression)? Suggestions greatly appreciated.
