XML processing in Elisp

Recent versions Emacs has built in xml support, and there are libraries available that give you DOM and even XPath capabilities. I've started experimenting with it as I want to process Eclipse Workspaces. Ideally, I should be using XPath, but that has too many dependencies for now (it depends on parts of Semantic). So, using the xml-parse examples on EmacsWiki.org, here is some simple code to get a the "userid" attibutes from all the "to" elements of the following xml data: 
  1. <?xml version="1.0" encoding="ISO-8859-1"?>
  2. <note topic="weekend plans">
  3. <to userid="1">Tove</to>
  4. <from userid="2">Jani</from>
  5. <heading>Reminder</heading>
  6. <body>Don't forget me this weekend!</body>
  7. <to userid="3">Bob</to>
  8. <from userid="4">Sammy</from>
  9. <heading>Alas!</heading>
  10. <body>A new week!</body>
  11. </note>

Opening an image in Opera 9.5 spawns multiple tabs

I recently started seeing a bizarre problem in Opera. I believe it only happened in Opera 9.5 but I may be wrong. I suspect it may also be linked to Irfanview. Basically, when ever I opened an image via the context menu, or clicked on a image link, a gazillion (ok, 10 - 20) tabs would open, trying to load something from the cache directory - yet still no image.

I found the solution to the problem yesterday, in the Opera Forums:


Seems like something got mixed up in your file type associations. Probably the best thing is to reset them all.

Creating a Blogroll the Drupal way

By voyager - Posted on May 24th, 2007
Tagged:  •  

My shiny new blogroll is built using the Drupal modules Content Construction Kit (CCK) and Views. The CCK lets you create new "content types" very easily and without writing a line of code (which is a good thing in this case).
Everything in Drupal is/should be a node. This post is a node, of the type Blog. CCK lets you set up a collection of data fields into a new node type or add custom fields to existing node types.
