Expedia API - open to bidding

I am busy with a site for a client that does tours and one of their tabs contains information about the hotels that their customers will stay in. I want to populate and update my mysql database using the expedia api but unfortunately I have no knowledge of xml and I cannot find anything online to steer me in the right direction. I am looking for a page that will store the info into php variables so that I can insert them into the database. Can this be done, can you help and what will it cost? Kind regards
