This may just show my lack of understanding of XPath, etc., but when I
apply [1] to TestParsers, I get the following output:

Solr Version Control System
Overview
The Solr source code resides in the Apache Subversion (SVN)
repository.
The command-line SVN client can be obtained here or as an
optional package for cygwin.
The TortoiseSVN GUI client for Windows can be obtained here.
There
are also SVN plugins available for older versions of Eclipse
and
IntelliJ IDEA that don't have subversion support already
included.
Here is some more text. It contains a link.

-----------------------
Anyone have any insight as to why wrapping a XMLSerializer inside of a
MatchingContentHandler is causing such a problem?
Thanks,
Grant
