Thanks David. My apologies for the break in transmission: Xmas etc...
I've had a go - a few goes actually - at getting this to work, and I'm
still not getting anywhere.
I've inserted the following into my sitemap.xmap file:

 <map:match pattern=3D"**dirtyhtml**.xml">
 <map:generate src=3D"{project:content.xdocs}{1}/dirtyhtml/{2}.html" />
 <map:transform src=3D"{project:resources.stylesheets}/puck.xsl" />
 <map:serialize type=3D"xml"/>
</map:match>

It's the first entry in the <pipelines> section. Bearing in mind what
you said about the directory separators I tried a few variations on
the syntax. I found the result either passed the html page straight
through, which I assume means that the match isn't being made, or
produced the following error:


test\src\documentation\content\xdocs\dirtyhtml\default.body.html (The
system cannot find the file specified)

This happened when I used the code above.

As a matter of interest, how would one extend the match to include
files with .htm and .asp extensions?
