Subject: [xsl] XPath behaviour From: Lars Rönnbäck <lars@xxxxxxxxxxx> Date: Thu, 28 Dec 2006 03:10:35 +0100 (CET) |
Dear list, I am having a problem with an XPath expression. The program I am using is Stylus Studio 2007 and I am building an XSLT 1.0 stylesheet. Within the program you have access to an XPath Query Editor. I used that together with an XML file to build the following: /calendar/year/month/day[@month = 3 and index = 21]/(.|following::day)[@phase = 2][1]/(.|following::day)[@weekday = 6][1] This path will correctly find easter when I execute it in the query editor. However, if I create a simple stylesheet that uses the path in a <xsl:value-of select="..."> I get a compilation error. Using the built-in processor I get the message: Testing.xsl (5, 2): Expected node test in value-of Using MSXML6 I get the message: NodeTest expected here. /calendar/year/month/day[@month = 3 and index = 21]/-->(<--.|following::day)[@phase = 2][1]/(.|following::day)[@weekday = 6][1] Using Saxon 6.5.5 I get the message: com.icl.saxon.expr.XPathException: Error in expression /calendar/year/month/day[@month = 3 and index = 21]/(.|following::day)[@phase = 2][1]/(.|following::day)[@weekday = 6][1]: Unexpected token [(] in path expression Using the .NET XslTransform I get the message: System.Xml.Xsl.XsltException: '/calendar/year/month/day[@month = 3 and index = 21]/(.|following::day)[@phase = 2][1]/(.|following::day)[@weekday = 6][1]' is an invalid XPath expression. ---> System.Xml.XPath.XPathException: Expression must evaluate to a node-set.
