Help, Building a Real Estate Listing Aggregator

[Exclusive Listings]

I currently am developing an RE classifieds portal and I want to take it to the next level. I want to construct an rss feed aggregator for property listings and then be able to crawl the feeds to find exactly what one may be looking for. Setting up an aggregator and a crawler to work in tandem shouldn't be that tricky but what I need help with is finding a program or script that can pares the feeds into a viewable table on my site. (i.e) property pic______description_______price_____

The process would look like this. Enter property search query > engine crawls feeds > results displayed in a table as described above.

I am basically just trying to mimic Edgeio, Propsmart and sites like that..

Any Ideas or suggestions on how I may execute this?

Eureka! I think I found part of the solution by using Ruby to handle the aggregation.
