del.icio.us RSS

This Add-on does not really extend the functionality of SimplePie, but it does extend the get_categories() function. In the del.icio.us- RSS there are only spaces to seperate the 'Tags'. This is not handy when you want to iterate over them to give them a certain markup. This extention explodes the one category-element and inserts them into the SimplePie_Item like the rest of them. Also, it's got a 'is_delicious' variable to base diverting mark up on.

1. Create a new file called simplepie_delicious.inc and place it in the same directory as your simplepie.inc file.
2. On the SimplePie-enabled page you want to use this extension on, make sure you include it in the same way that you include simplepie.inc.

• get_categories()
  Now returns separate tags in stead of one line.
