[xquery-talk] Linking Saxon through to exist database

Since this is a product specific question, it should probably be 
discussed on the eXist mailing list. Anyway ...

You can access documents via HTTP using e.g.

http://localhost:8080/exist/rest/db/test/a/books.xml

Using this link within e.g. an XSLT will be ok (though not efficient for 
larger docs). BUT: collections are a different matter since different 
XQuery implementations use different concepts of what consitutes a 
collection.

http://localhost:8080/exist/rest/db/test/a

returns an XML fragment listing the collection contents. If you really 
need to, you could pre-process that somehow to include all collection 
member documents. But as I said, it might not be very efficient.
