Sorting search results in Cocoon
I'm kind of new at this whole XML/XSP/XSL thing, so if this has a simple
solution,
please bear with me.
Here's the situation: I have a search engine that passes out search results
as XML
to anything that can make a HTTP request to it. When it returns the results,
it looks
something like this:
<searchresults>
<result>
<name>Result 1</name>
<description>This is result 1</description>
<href>http://here.com/index.html</href>
<score>2.3</score>
</result>
<result>
<name>Result 2</name>
<description>This is another result</description>
<href>http://there.com/index.html</href>
<score>1.2</score>
</result>
etc.
</searchresults>
The <result> elements can be repeated infinitely depending on how many
search
results the engine finds that match search query. <score> is the search
result's
ranking against the search query; the rest of the elements in <result> are
self-explanatory.
The search engine returns ALL matches at once in one big XML file. There
could be a dozen search results, 100, or 1.
How would one go about limiting those results in Cocoon? Say I get 100
results,
but I only want to display the top 10 results by score. I'm assuming XSP
is the answer, but I've been going nuts trying to get this stuff to work.
I have O'Reilly's "Java and XML" on back-order, so hopefully that can clear
up my confusion, but until then, anybody got any ideas or some direction
for me?
Thanks for any help.

The most efficient way would be to limit the XML source - having the search engine do the sorting and limiting for yourself. That being impossible, you can do it with an XSLT transformation for sorting:
http://www.w3.org/TR/xslt.html#sorting
http://www.w3.org/TR/xslt.html#copying
and another to select the topmost N:
http://www.w3.org/TR/xslt.html#section-Applying-Template-Rules
http://www.w3.org/TR/xpath.html#function-position
You can get better help at XML/XSL specific mailing lists.
