Escrever algum software

Windows PHP Hi there, I need a script to work in wordpress blog and convert a short text rss feed into a fulltext rssfeed. Some blogs (only wordpress) have the reading option short rss, so you cant get the full article through its url feed. As an example to give you some help, there is this site: [login to view URL] In this site you give the url feed and returns the full rss feed. Thats exactly what I need. Regards. Sonia
