or more interestingly (and still very simple):

<map:match pattern="**.html">
  <map:generate src="{1}.xml"/>
  <map:transform src="somestylesheet.xsl"/>
  <map:serialize type="html"/>
</map:match>

This will match every request that ends with a .html, and will use the 
matched part of the URI (**) to substitute the {1} portions further down 
below, i.e.

   URI request                                 XML source document
-----------------------------------------------------------------------
http://host:port/mountpoint/index.html    ->   index.xml
http://host:port/mountpoint/foo/bar.html  ->   foo/bar.xml

Other cool features are aggregation (merging several XML pipelines into 
one - think 'portal' or 'frames-on-steroids'), and a host of components 
doing RDBMS-querying, PDF-serialization, SVG and whatnot.

Yes, it's much more elaborate than Xalan packaged as a Servlet, but it 
offers you much more bang for (no) buck.

HTH,
