I have an RSS reader script that I used to parse RSS feeds. On my homepage, I use it to parse one feed currently using an [B]include[/B] command, and the feed URL is a variable. However, I would like to parse two feeds on my homepage using the same script. How would I do this…?
Basically it just includes the RSS reader using an include command, and the $Feed provides the actual feed URL. I just need to get the RSS reader to run through twice with two different URLs on the same page. I can post the source of the RSS reader script if you'd like.
How would I implement the "again" command properly in this case?

Place the URL of an RSS feed in the $Feed variable.
The $rss_channel array will be filled with data from the feed, every RSS feed is different but by and large it should contain:
Array { [TITLE] = feed title [DESCRIPTION] = feed description [LINK] = link to their website
[IMAGE] = Array { [URL] = url of image [DESCRIPTION] = alt text of image }
[ITEMS] = Array { [0] = Array { [TITLE] = item title [DESCRIPTION] = item description [LINK] = a link to the story } . . . } }
By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array structure so you can format the information as you see fit.
>>>PAGE VARIABLES $Feed [URL] = URL of the RSS feed $PrintTable [True/False] = Specify whether or not the feed needs to be enclosed in a table $Description [Text] = Description underneath the page header, if needed
