how to get data from api rather than home, element, table tag?

I am tryingh to get data from this  api:

http://api.twitter.com/1/users/show.xml?screen_name=geekygirldawn

I am using get data> web option but i am getting this as data:

Image may be NSFW.
Clik here to view.

and then i am clicking on the arrow icon:

Image may be NSFW.
Clik here to view.

then also it's not showing  the data and showing this:

Image may be NSFW.
Clik here to view.

It's not showing the data and showing html tags!! Where i am doing mistake ? 

I also read somewhere that go to Transform tab in edit query and use convert to table option but I am not getting that option where this option is in transform?

Thanks for your time.
