php script to get a xml feed and output differently

I have an URL here that returns xml response: [login to view URL] What I want is a php script that can parse this xml response and output the result in a different format something like this below: [login to view URL] The way the parsing will work is for each "doc" returned from the URL: coupon_text will become title in the new format need_to_know will become description category will be category deal_url will be link thumb_100_url will be image_link buy_text will be price Channel information can stay as is for now, I will change it later: <channel> <title>Your Product Feed</title> <link>[login to view URL]</link> <description>Your Store Description</description> For now we don't care about "condition" and "display_order." If you need to use any PEAR packages or any libraries, please include that information along with your bid.
