===============================================
Okay here is what I did
NOTE: I commented out several functions for my USE
using the TAG {PHP:your_dir/with_rss_file_below.php}
save the following below as a php file.
I have commented out several lines, but if you uncomment this then you have extended functions.
change the following
"http://news.bbc.co.uk/rss/newsonline_uk ... rss091.xml" => "uk",
with the url of your rss feed, I have 2 feeds there, so you need to delete whichever for this note to be random.
note: this is an array for a random picker, see the file, and play with this.
note: this is not my coding, and might be improved in the future
I find this script works well, there are also no conflicts with the script...
enjoy
regards
TriP.
