I want to create a web form that pulls in part of it's data from the information in an XML RSS feed.

Ideally the RSS feed would be displayed in a readable list and each entry selectable. When the RSS entry is selected it will bring in the XML data and automatically enter in into the various fields on a form. The form would also have other fields that would be unrelated to the RSS feed.

Is that achievable by modifying and adjusting scripts that exist? Does anyone know of a way to do this?

Any advice would be appreciated.
