Just for clarity. In eXist we do not load entire documents into memory, rather we load proxies to only those nodes that you address in your query. The nodes themselves are only really read during serialization, and that should be done in a streaming manner, so memory should not be an issue. However, even then it is still true in eXist that iterating over the documents instead of the transforms, just as you suggested, would be more efficient. -- Adam Retter skype: adam.retter tweet: adamretter http://www.adamretter.org.uk _______________________________________________ talk@x-query.com http://x-query.com/mailman/listinfo/talk
