A little XSL help please?

[Dennis]

[[Sorry I couldn't think of a better subject for this rookie question.]]

In my .xml I have something like:

<root>
<parent>
...
<child>
<keynode>thekey </keynode>
</child>
</parent>
...
<parent>
<keynode>thekey </keynode>
<valuenode>thev alue</valuenode>
...
</parent>
</root>

In english, what I would like to do in my .xsl is this:

When processing each /root/parent/child, use the value of keynode
('thekey') to look up a /root/parent somewhere else in the .xml with a
keynode which matches ... and retrieve the corresponding valuenode
('thevalue').

Is this possible?

P.S. I can manage the xsl:for-each part.

TIA,

Sure
<xsl:template match="root/parent/child">
<xsl:value-of select="../parent[keynode =
current()/keynode]/valuenode"/>
</xsl:template>

Should be
<xsl:value-of select="../../parent[keynode = current()/keynode]/valuenode"/>
actually.

OK.

Can you recommend a good online resource for beginners. I have a
programming background so I pick up on things quickly. I have been using
www.w3schools.com and just googling for answers to my questions, but I
don't see anyplace that I would call a comprehensive reference site with
good examples.

Thanks,

Many good tutorials/articles are available at http://www.ibm.com/xml.

For terse but enlightening examples of less-than-obvious patterns, see
the XSLT FAQ at http://www.dpawson.co.uk/xsl/sect2/sect21.html

(I've heard more complaints about the w3schools website than praise for
it. You might want to take its suggestions with a grain of salt...)
