Error handling with CFFEED?

Question

Hello, does anyone have a suggestion on handling errors from
CFFEED reads?

I'm reading an ATOM RSS feed from another site, but if there
is ever an issue with that remote site, it would prevent my page
from loading.

If, for example, the RSS feed wasn't available, I would get
an "Unable to read the source URL" error page.
What I would like to have happen would be the page to
continue processing, and instead of displaying the <CFOUTPUT
query = "myQuery">, instead display something like "There was a
problem with the newsfeed".

Is there any way to ignore a "fatal error" from a CF tag, and
just move on with processing the rest of the page?

The code I've used here is Adobe's example for the CFFEED
tag. The RSS URL I'm testing with is:

http://feeds.emsresponder.com/emsresponderrss/top_ems_news

Thanks in advance!

Use CFTRY and CFCATCH as suggested above. These tags can be used around pretty much any potentially problematic code.

A good idea might be to put a CFMAIL tag in the CFCATCH which will notify you if something is wrong - although, this depends on how many people you'll have viewing the page, because you could end up getting a lot of emails - I'm sure there must be a better solution somewhere though, just an idea really.
