   Re: [xml-dev] RE: Incremental transformations with Xalan and performance

[ Lists Home | Date Index | Thread Index ]

Do you happen to know if anyone has tried to build an XSLT engine that does
incremental transformations on incoming SAX events, without requiring the
building of a tree?

I advise you go and check the streaming XQuery engine from BEA. It is not XSLT but
XQuery, but given the fact that they are pretty much equivalent, it might solve your
problems. The details of how it works are given here.

The BEA streaming XQuery processor.
