Still no go unfortunately. Here is some very simplified code, which I've
also commented thoroughly, so the flow should be much clearer. I'd
appreciate any help figuring this out, it's pretty frustrating, since it
should work. I did something similar which is the whole basis behind the
dynamic live chat application at http://gutterstar.net/dynamic_live_chat.php
, which is working correctly using the same principles. This is very
confusing.

Well if you get your code down to one feed and its still not working send
it
again and I will have a go at it.

Thanks, I'll give it a go. I was able to get part of it working once
before,
I just wish I remembered how... Though even then, it only worked when the
page first loaded, which I guess sort of defeats the purpose.

Ok I was thinking of putting this up on my page and trying it but I
have a suggestion for debugging this.  Limit to testing it with one
rss feed and simplify the code as much as you can before you test it.
Once you get the more simple version working then you add the extra
feeds.

Hi, I've been trying to get this thing working for a few days now, but
I think I'm missing something.

I'm trying to work out a better and more dynamic method for loading
the news feeds at http://gutterstar.net/news.php All of these news
feeds are being loaded using the script at http://gutterstar.net/rss ,
which is rendered within a standard <script type="text/javascript"
src="http://rssScriptGenURLOutput.php?stuffVariables";></script>

My idea is that, if I could dynamically load each RSS feed when a link
is clicked, the load delay would be much less, and no page refresh
would occur to disrupt navigation.

So I wrote the test page at http://gutterstar.net/news_test.htm Which,
by all that I've read, should work, except that it doesn't...

I was able to get the code below to work briefly when the page first
loaded, but nothing after that. Now it doesn't even work when the page
loads for some reason. The dynamic aspect just isn't working at all.
I've saved out the live DOM to see if it's adding the correct script
to the right Div, and everything appears to be updating correctly in
the DOM, but I can't see anything on the page itself, which is really
weird. Anyone know what I'm doing wrong?
