Urgent: parse xml

We need a script that parse a remote XML file and returns data from two tags within it. That is "title" and "body" within "forecast". We would like the result as a text string that we can format, i.e.: Weather forecast: "title". "body". Lon term: "title". "body" Link to XML: [login to view URL] We also need to implement this into our CMS. We do that, but might need some advice on how to do it; also a part of the project. CMS based on PHP. Parsing script probably best done also in php.
