API / XML File import

Hi everyone!

I am wanting to create a weather site. It is a hobby of mine. Anyway I have API / XML file from here http://wiki.wunderground.com/index.php/API_-_XML

The question is how do I get that link’s XML to display as a post in wordpress? I tried to using the Feedwordpress plugin, but it keeps saying it isn’t a feed.

So if someone can help me get this feed: http://api.wunderground.com/auto/wui/geo/GeoLookupXML/index.xml?query=94107
imported in automatically that would be great!

Thank you!
