Tools for XML Deviants

I’m unearthing bits and pieces of code that I’ve got lying around my hard drives at home, so I can finally finish them off and post them to the net.
The first bit out the door is actually nothing new: these tools have just been languishing, somewhat abandoned, on some free web space I was using for a while.
Anyway my Tools for XML Deviants are now back online. These are two Netscape sidebars (plain HTML rather than XUL currently) that provide quick access to the search functions of various XML news sites and, most usefully to me at least, the XML-DEV toolbar which provides easy access to the XML-DEV archives.
Today I started tinkering with a sidebar for the W3C mailing list archives, as I occasionally surf through the recent postings of several of them.
