If you want to use Linux convert XML documents to some text format that you
can easily parse with CMS tools, I'd suggest using XSLT. You can write an
XSLT stylesheet that transforms the XML document into the text format you
need, and use an XSLT processor to run the files through it. You can
prototype an XML server such as you describe in PERL, using the XML::XSLT and
Net::Daemon packages. For production, I'd suggest a simple C socket listener
calling the Xalan-C library. Your XSLT stylesheet is the only custom part,
and it would be the same for PERL or C XSLT daemons.
Hit me up for more details if you want to.
