Subject: [xsl] determining position based on predicate From: Terry Ofner <tdofner@xxxxxxxxx> Date: Fri, 15 Oct 2010 13:05:14 -0400 |
I am attempting to find the position of an element based on a predicate. Is this possible. Here is a snippet of incoming xml: <chapter> <tocItem startNum="38" endNum="39"> <sublesson> <subtitle>Topic A</subtitle> <subpages> pp. 4041</subpages> </sublesson> </tocItem> <!--much more like this--> <tocItem startNum="40" endNum="41"> <lesson> <lessontitle>Lesson A</lessontitle> <subpages> pp. 4041</subpages> </sublesson> </tocItem> </chapter> The following count statement does not seem to work. Is there a way to find a position based on a predicate? <xsl:template match="chapter"> <xsl:for-each select="tocItem"> <xsl:choose> <xsl:when position()=count(.[lesson/lessontitle='Lesson A'])-1"> <!--do some stuff and close when, choose etc.--> I can use position()=last()-1 but the desired position is not always second to the last. Terry
