I just got a mail asking about the source that goes with one of the Wrox books I worked on. Seems it's no longer available on the Wrox site (which perhaps isn't surprising, considering they've gone bust). Took me a while to find, my backups are by date rather than content, and I don't keep a diary…
Any road up, the book is "XML Application Development with MSXML" - one of my rare forays into the M$ world (I was actually pleasantly surprised by how well Microsoft's XML kit worked). The (undocumented) source is a mix of server- and client-side Javascript and XSLT.
Chapter 16 : Case Study
(message brokering)
"A Custom XML Messaging System"
(trouble tickets helpdesk app)
Chapter 8 : Linking and Pointing
(XPath, XPointer and a bit of RDF)
"A Prototype Annotation System"
Amazon.com: Books: XML Application Development with MSXML 4.0
