Craig,

At 07:19 AM 4/29/2008, you wrote:

The transformation I'm trying to perform creates a series of groups from the source document based on different criteria and does lookups. It provides the results as a set of tables in the output document. Using the <xsl:for-each/> approach creates repeated sets of results, one for each input document. I also tried:

<xsl:apply-templates select="collection('collection.xml')/yourcontent"/>

This led to the same output, where I got the combined results once for each document in the collection, which seems strange.

Does this make sense?

Well, you're specifying that you want each 'yourcontent' document to be processed, and so if your logic for processing them says to process all of them, that will happen once for as many documents as you have.

Bind these documents to a variable (I think Mike showed you that?) and then perform your grouping logic once over the set. (Or don't even bother and select items straight from the collection, as in

<xsl:for-each-group select="collection('collection.xml')/yourcontent/your/item"
  group-by...

In any case, and especially if you're running out of memory, you might be able to streamline things considerably by pre-processing your input.

Cheers,
Wendell
