dom xml + xsl chaining how to...

[$im@n]

i tried use transformer to transform xml (dom object) and xsl, no
problem...
i want to have many stylesheet "chain" together...(i want to dynamic
assign xsl)
i used SAXTransformerFactory and xmlFilter.setParent(..) to relate all
xsl together..., no problem as well...

but when i use xsl chaining, i can only use static xml file because
xmlFilter3.parse(new InputSource("index.xml"));
InputSource will only take static filename...but my xml is dom
(dynamically construct)

how can i use dom tree as xml and use xmlFilter together?

thanks.
