RE: Transformer adds unwanted newlines

You're doing a two-stage transformation here: first a transformation using a
stylesheet, which then feeds its output in the form of a SAXSource to a JAXP
identity transform which converts the SAXSource to a StreamResult.

I don't know why you're doing this or why it adds newlines, but it does mean
that the xsl:output is going to be ignored because the output of the
stylesheet is not serialized.

What happens if you remove the (apparently unnecessary) second step?
