FlexPMD Client for Viewing Generated XML files - Source Code

I recently came across FlexPMD, a neat little Java tool that runs through your Flex/AS3/Air code and creates an XML file of all the problems (violations). It should be something everyone does before committing files to their own repository. I didn't see a nice UI tool to view what can sometimes be a massive XML file, so I created a little AIR app that allows a user to select the xml file, navigate the classes, and view the detailed information of each error. Simply copy/paste this MXML code into your Flex Builder 4 AIR application (or remove the 's' and 'fx' namespaces if you're still on Flex 3).
