I need a XML importer for Open Realty

The script/addon shall fetch xml feeds from several different real estate websites and import the listings into the openrealty database on my site.

The script should update the xml feeds regularly using CRON

The master Admin will need the ability to add multiple datafeeds for each individual agent and also choose if the agents sold properties are moved to a sold category or deleted.

The listings from each xml feed should be listed under the agents for each xml feed, without affecting the users other listings.

The script/addon should import photos from a Full URL located in the XML file. Thumbnails are to be generated automatically.

Listings that already exist in the database are updated in order to maintain the listing ID, if the listing is sold it is moved to a sold category or deleted depending on the settings in the script.
