JQuery :: XML Parsing Doesn't Work In IE 8 - Parse An Element In IE?

after a lot of investigations I don't know the answer why the attached sample doesn't work properly. Please take a look at the attached sample. That's a html file. Because of forbidden uploads of html files i removed the file extension. So please put after download the file extension ".html" on it and take a look at the sourcecode. The goal is to parse the included xml structure and to show the some information as checkboxes with a title or description.

The checkboxes are parsed based on a xml attributes. That works fine. The title/description should be parsed out of an xml element. That doesn't work. I don't know why. In my opinion the reason is the way of doing of the element pasring which is not right defined for IE.
