Make Wordpress Posts from XML Files

Require a light-weight php script that can read xml files that are uploaded to a directory and create a wordpress post, with the content of each xml file using XML-RPC. The script would be run by cron every few minutes, checking for new xml files that have been uploaded. When the script detects a new file has been uploaded, it should create a new wordpress post, using the structured data inside the xml file. once a wordpress post has been created the original xml file should be then moved to a sub-directory for archiving. Time frame: 1-2days.
