Re: File management via XSLT

I'm using <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">.

Everybody uses this in the style sheet. The interesting point is: what
XSLT processor are you using? In case you don't know what an XSLT
processor is: do you run the transformation in IEx?

Command line processors generally allow you to write the transformation
result directly to a file. The details are processor specific, check
the relevant documentation (often "running" or "invoking").
If you use MSXML from within IEx, get the MSXML command line tools,
which also allow you to write directly to a file.

If you want to create multiple output files for a transformation, you
have to use a processor specific extension, as Jarno already told you.
