Creating XML from another XML based on search queries

I have a large rss that is located here while my site is here. I need a step by step procedure in creating a rss feed based on the search queries that users type in. The resulting rss feed should be based on the large rss feed. Is there a way to d开发者_Go百科o this using xhtml, javascript or html?

No. You will need a server side scripting language to process the data sources, and merge them into a new one.

Hey guys I finally found the simplest answer to my problem. I just used Yahoo Pipes. This would be very useful for people who can't access their servers because their sites are hosted for free AND they need the rss to contain a cross domain policy xml because they use flash. Hope some would find this resource useful. It took me a month to find it. No need for javascript or jquery.
