Modify to work with 1.2

I was getting an error in my simple pie extension, which was still using an old beta version. It was quite simple to change the code to work with the new version, so my code is below...

The error I was getting is: "Object of class SimplePie Enclosure could not be converted to string in simplepie.inc on line 1452"

Doesn't work?

For those curious to try this extension, save your time and look elsewhere. The problem might be that the "simplepie.inc" file is not available to download from their website, instead they have split it up into classes. The compiled, single-file version (simplepie_1.3.compiled.php) didn't work either, despite replacing "simplepie.inc" with "simplepie_1.3.compiled.php" in the simplepie_mediawiki.php. I gather that since this extension hasn't been updated since 2006, it simply no longer functions with more recent versions of mediawiki (I'm using 1.18.2). -kotra (talk) 07:45, 3 October 2012 (UTC)
