[Resolved]Xpath

[Martin Wilson]

hey, sorry for the non-descriptive subject, but this really can't be described in a few words or i'd have used google :-)
ok...given this XML as a simplified example:

<a>
     <b>x</b>
     <c>1</c>
</a>
<a>
     <b>y</b>
     <c>2</c>
</a>
<a>
     <b>z</b>
     <c>3</c>
</a>

<d>
     <b>y</b>
</d>

For each d element, I want the value of c in the a element with a matching value of b.

Got that?

Fixed it my self, for those that want to know...

add something like:
<xsl:key name='a-search' match='a' use='b' />
before the <xsl:stylesheet> element.

then the XPath is:

key('a-search', b)/c


hope that helps someone
