I have a page which uses RSS2JS to display an RSS feed. When the feed contains items, all is well. But when the feed does not contain any items, no content is displayed. It would be preferable to me if RSS2JS would write something like "There are no announcements at this time. Check back later!" rather than leaving a blank spot on the page.

RSS2JS generates code that looks like this when the feed is empty.
Code:
<div class="rss-box"><ul class="rss-items"></ul></div>
I thought it might be possible to use Javascript to replace the <ul> tags with something like this after loading:

Code:
<div class="rss-box"><ul class="rss-items"><li>There are no announcements at this time.  Check back later!</li></ul></div>


Sadly, I know next to nothing about Javascript. Any suggestions? I'd be happy to credit you in the code, for what that's worth!
