As far as I know, most xslt processors expect input to be accessed as an xml tree, dom (not necessarily "the" DOM, but something similar enough). This is generally built using a streaming interface like SAX. So perhaps you could just implement standard DOM API?
Or alternatively, if it's easier, SAX interface using which processors build internal trees. -+ Tatu +- --- On Sat, 2/28/09, Johan Zxcer <nab...@zurahn.com> wrote: > From: Johan Zxcer <nab...@zurahn.com> > Subject: Usage model - no source XML, just api calls > To: xalan-j-users@xml.apache.org > Date: Saturday, February 28, 2009, 10:34 AM > I am new to the world of XSL and Xalan, and I've been > trying to understand > whether my usage model is possible, common, or advisable. > I simply want to > use a stylesheet with no source document, instead using > only calls into my > API to fetch data.
