This is confusing:

There is no "text" attribute with value "aa" in the two xml documents.


It's true that nobody's replied to the first post until now. I didn't,
because I didn't find a complete and clear description of the problem
-- one has to put some effort in specifying a problem in precise
manner, this is a logical pre-condition for people being able to help.

Additionally, if performance is to be optimised, this requires that
real (or at least realistic) input files are included.

Uhhh, rats, I missed that and at least 2 typos (though I can't find them now for the life of me :-). So sorry!

Here are the revised feed files. Lets assume the @id attribute on each story is unique. Again, the following applies to the latter question in http://www.biglist.com/lists/xsl-list/archives/200503/msg00647.html . That is, I'm intertested in a technique to generate final.xml in 1 pass.


feed1.xml
======
<feed>
<story @id="1" @date="1" text="a"/>
<story @id="2" @date="2" text="a"/>
</feed>


feed2.xml
======
<feed>
<story @id="1" @date="1" text="a"/>
<story @id="2" @date="2" text="a"/>
<story @id="3" @date="1" text="b"/>
</feed>

If feed2.xml were the "current" feed, and feed1.xml the prior one, I want to end up with the following, in 1 pass. Note that <story @id="1".../> is passed through, though unchanged, because abother story with the same @date, <story @id="3" @date="1".../>, is new.

final.xml
=====
<feed>
<story @id="1" @date="1" text="a"/>
<story @id="3" @date="1" text="b"/>
</feed>

I hope I've provided sufficient context and detail. I'm desisting posting code because it's voluminous (there's little to pare down); I shall should anybofy feel it'll help.

Thank you.
