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!
Thanks,
Ashish

Subject: [xsl] Extract values from first occurrence of a node
I am trying to translate XML via XSL/XSLT need to specifically extract the
values from the first occurrence of a particular node and ignore the rest of
that same node.
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.
Thanks,
Matt
