Hey I followed the link of threedruidnoob's blog to this post because I'm trying to solve the same problem; getting a nice achievement feed on my blog.

I kind of have something working, but it's a hack- I'm just regex shredding the achievements off of the rendered HTML page. I think the most elegant solution would be to get a Yahoo! Pipe to Fetch the XML file and then render the relevant xml items as a RSS feed; unfortunately the "Fetch Data" module seems to not be able to retrieve the armory data as xml, because wowarmory.com detects that it is not a modern browser, and serves up server-side generated HTML. Does anyone know a way around this?

Other than that, I'd just like to know if anyone else has had luck getting nice achievement feeds onto their blogger.
