Wordpress XML-RPC automatic posting via XML feed

Hi! I have an XML feed from a content provider named Yellowbrix for news content. I want to be able to take said XML feed and automatically post it to a wordpress blog. The feed URL looks something like: http://api.yellowbrix.com/api/service=headlines&method=xml&id=USERNAME&password=PASSWORD&link_type=story_id&enabletext=1&numhl=1&ONLY_STORY_IMAGES=1&category=Economy/Markets I can't just directly import this into Wordpress via a plugin like feedburner. An API is available for the XML feed.
