Unfortunately the XQuery command line doesn't have any equivalent to the -x flag on the Transform command line, so I don't think this can be done from the command line. You can do it from the Java API, of course - and you could create yourself an extended command line by modifying the net.sf.saxon.Query module, because it's just an interface built over the Java API.

Hmmm. Ok. I can work on getting the resolver in place. In the mean time, testing the query itself over a fairly large sample of about 1000 documents, my query throws a out of memory exception ... Exception in thread "main" java.lang.OutOfMemoryError: Java heap space Can one incorporate saxon:discard-document() into the query to help recover memory? m./

>Can one incorporate saxon:discard-document() into the query to help recover memory? Yes, you can.

Still not getting there. Maybe you can help flesh out the problem a little. I have a directory structure of documents. I use collection('/directory/sub-directory?recurse=yes;select=.xml') to gain access to the document collection. I've tried two approaches, neither of which work. Approach 1 is: let $uris := collection('/directory/sub-directory?recurse=yes;select=.xml')/saxon:discard-document(.) for $uri in $uris ... return ... This does not resolve the memory problem. Approach 2 is: let $uris := collection('/directory/sub-directory?recurse=yes;select=*.xml') for $u in $uris let $uri := saxon:discard-document(doc($u)) .... return ... This doesn't work because the collection function returns document nodes, and what doc wants is a URI. What is the work around, or is there none in this situation?

Here is a third approach that appears to work: let $uris := collection('/directory/sub-directory?recurse=yes;select=*.xml') for $u in $uris let $uri := saxon:discard-document(doc(document-uri($u))) is that the best way to do this?
