Subject: [xsl] Beginning an XPath expression with a function call? From: "Monier, Yves" <Yves.Monier@xxxxxxxxxxxxxx> Date: Fri, 7 Mar 2003 17:45:37 +0100 |
Hello, Given an XPath expression (for example //foo/foo2) that works for a given xml, I would like to use the substring-before function, to keep only the characters in //foo/foo2 before '-'. The XPath would then become substring-before(//foo/foo2, '-') It seems that both XPath 1.0 specs, MSXML 4, Saxon 7.4 and XalanJ 2.5 refuse such construction (e.g. having a function call as root of an XPath expression). Note that it works with Xalan C++ 1.4. Should it, or not, regarding the specs? Do you know if there is a simple "legal" XPath-only-based solution to achieve the same result? Many thanks, Yves PS: For MSXML 4 I use an XMLDOMDocument + the selectSingleNode function. For Saxon and XalanJ I wrote programs derived from their respective XPathExample and ApplyXPath samples. For XalanC I wrote a program derived from its XPathWrapper sample). Saxon error is "A sequence of more than one item is not allowed here". XalanJ error is "Can not convert #STRING to a NodeList!".
