Some of you probably already know that all OpenOffice.org (a very good open source office suite) documents are actually XML files. Just take any utility that supports zip archives and, well, unzip the OpenOffice.org document of your choice. XML is an open and very flexible standard. Many web pages are written in it for example and it is also used by instant messaging system Jabber (or XMPP if you like it). If you would like to do more with OpenOffice.org XML dialect, like easily converting it to web pages (or other forms using XSLT) and using all the power of styles, then I highly recommend you take a look at article Hacking Open Office at XML.com. Thanks goes to Peter Sefton for writing it.
