Re: Extract values from first occurrence of a node

You could sort using the first five (presuming they will always be numbers)
and then output only the first B
<xsl:template match="A">
<xsl:for-each select="B">
<xsl:sort select="substring(.,1,5)" data-type="number"/>
<xsl:if test="position() = 1">
<xsl:value-of select="substring(.,7,4)"/>
</xsl:if>
</xsl:for-each>
</xsl:template>

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
