| I agree a forward-only streamable subset of XSLT/XPath would be very useful. | Upon further investigation streaming-transformations may turn out to be a | completely different animal. Chris, How close in your opinion is Michael Kay's <saxon:preview> extension documented at: http://users.iclway.co.uk/mhkay/saxon/saxon6.0/extensions.html#saxon:preview to solving the customer problem that a "streamable subset" is trying to accomplish? In the database/XML environment the problem is typically transforming huge XML documents which are huge because they are thousands or millions of repeating "subdocuments" wrapped by an outer, containing element. Not unsurprisingly these "subdocuments" often are produced from rows in a database query. If the transformation that needs to be performed just needs to work on each <ROW> at a time (that is, each "subdocument") -- but never needs to do things like select the last() element or navigate back to the "/" root -- it seems like this kind of solution may be workable. Is the "streamable subset" you're thinking of trying to solve the "large document" problem, or some kind of browser-side, incremental transformation? Just curious. ______________________________________________________________ Steve Muench, Lead XML Evangelist & Consulting Product Manager BC4J & XSQL Servlet Development Teams, Oracle Rep to XSL WG Author "Building Oracle XML Applications", O'Reilly http://www.oreilly.com/catalog/orxmlapp/
