Subject: RE: [xsl] Extract values from first occurrence of a node From: "Tengshe, Ashish" <Tengshe.Ashish@xxxxxxxxxxxxx> Date: Wed, 16 Jul 2003 11:25:58 -0500 |
Try this <?xml version="1.0" encoding="iso-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="A"> <xsl:value-of select="substring(B[substring(.,1,5)='12344'][1], 7, 11)"/> </xsl:template> </xsl:stylesheet> Note that even if you don't use the [1] in the expression, you get the first node only by default. Though I've kept that so that you know where to put [2] (second node matching the criteria) if you need it!

I was attempting to use preceding-sibling::nodeset/node to verify if the match has already been made, but having little luck because I not only need to match the node but match substrings of the node's value. Example XML: <A> <B>12345 ABCD</B> <B>12344 ABCD</B> <B>12333 EFGH</B> <B>12344 WXYZ</B> </A> What I need to do: Recognize the first <B> with 12344 (substring from 1 with length 5) and extract ABCD (substring from 7 with length 4), but ignore all other <B> This is a very basic example, the XML I am working with is a bit more complicated and it is being translated via XSL-FO for PDF generation. The biggest problem I am having with XSL/XSLT is detaching from my procedural language experience! From my experience, I am having success in mapping singlular nodes but more difficulty when trying to accomplish "decision logic" in a non-procedural manner. Any suggestions or recommended reads would be great.
