XML is a fine intermediate format, and to use it for this purpose is a
worthy goal. However, it is not necessary to use XSLT to perform
transformations. The SAX2 XML parser (implementations in your chosen
language) calls class methods as it sees certain parsing events. SAX2 also
defines filter classes, that filter these events based on any criteria.
Writing your own filters and composing them (Chain of Responsibility
pattern) allows quite complex manipulation of XML data, with output not
restricted to just text, which I believe XSLT is. Anyway XSLT has a
non-obvious syntax (to me), and is difficult to debug. Use of XSLT will
require yet another tool to be installed and versioned.
I use chains of filters to turn XML build logs into detailed webpages and
brief email messages.

Hum... I've read a lot about XML but have never actually tried to use it.
What set of tools do you use/recommend?
