You haven't defined the namespace in your stylesheet - you won't be
able to match any elements in that namespace until you define it and
give it a prefix, and then adjust your match patterns:

<xsl:stylesheet xmlns:msg=3D"http://www.valid_url.com";  ...>

and

<xsl:template match=3D"msg:message">

As far as I can see that's all your problem is... no need for two passes.

Sorry andrew, but this has been tried and does not seem to work. Is there
something I am missing here, or is my original question valid?
