Simple Import from url

I have a site which was built on a 'beta' version of Drupal 7, and therefore not able to take new modules from drupal. I have a blog with ~150 posts which I'd like to import into a W/P site, but the tools I've found so far all require a file to be uploaded.

Is there a quick 'upload from url' where I can give the drupal feed address, and have them imported?
