xml inventory feed

Im looking for a mod to read suppliers xml inventory feeds. Seems more and more drop shippers are putting it out there. I cant find one in forums but admittedly, Im not sure my searches are the most effective here.

I need to be able to update my inventory at least once a day on many products.

Anyone have anything in place right now and can point me in the right direction?

Thanks.

Since all the xml inventory feeds from different drop-shippers would have their own layouts, I'm not sure how a simple mod would work for all of them.

What I did was create a php page that gets the feed from the drop-shipper, queries the products database for each item and then queries the xml feed for that item and updates the inventory level.

I have a cron job on the server access the page a couple times per day to update the inventory levels.

One added benefit is that any product not found in the feed is tagged as discountinued.
