We're talking JAXP here, for those who are mystified...

The best way to pipeline the output of one transformation as the input
of another is not using StreamResult/StreamSource, but using SAX. There
are various mechanisms in JAXP to allow such pipelining. You can compile
a transformation as a SAXFilter, in which case it can be inserted into a
SAX pipeline along with other SAXFilters (which may or may not be XSLT
transformations). You can also wrap a Transformer into a SAX
ContentHandler, which you can then use as the SAXResult of another
transformation.

But if you must use StreamResult/StreamSource, then you can always
create a StreamResult for the first transformation based on a
StringWriter, and the use a StringReader over the same String as the
basis for the StreamSource for the next transformation.
