Subject: [xsl] Counting Nodes From: "Richard Jinks" <cyberthymia@xxxxxxxxxxx> Date: Mon, 26 Nov 2001 08:46:48 -0000 |
Hi More of an XPath question than an XSLT question, but it arose from an example transformation, so this seems like a good place to ask... Is the following expression legal? count(//|//@*) It is supposed to count all nodes and attributes from the current context node. The reason I'm asking is that I'm currently evaluating a few different XSLT processers, with a view to using one of them in a product I'm working on. I've noticed that different processers handle it differently, the main stumbling block being the "//" by itself. Usually, they work separately (i.e. count(//) and count(//@*) ), but a couple (e.g. Apache's XalanC) seem to fall over when they are combined as above. I've tried reading the XPath spec and the XSLT Programmers Reference (2nd Ed), but I can't arrive at a conclusive decision. They appear to imply that I can't use the // by itself, needing to follow it with a node set (i.e. //* (which won't help, btw, as it doesn't count the text nodes) ), but there are sections which suggest that I can use it as a node set (e.g. AbbreviatedRelativeLocationPath, p354 of above book). Please can someone help my confusion? Thanks, Richard Jinks _________________________________________________________ Do You Yahoo!?
