Re: Failing gracefully when using xmlParse()...
You could use cfhttp to load the xml data into a variable, then parse the contents on a successful retrieval. --Ben Doom Che Vilnonis wrote: How can I fail gracefully when using xmlParse and the feed is not available/online? cfset xmlFeed = xmlParse(http://www.somedomainwithrssfeed.com/keyword.xml;) When using cfhttp, you could always use cfif findNoCase(200, cfhttp.statusCode) to test for success.

How can I fail gracefully when using xmlParse and the feed is not available/online? cfset xmlFeed = xmlParse(http://www.somedomainwithrssfeed.com/keyword.xml;) Use try/catch. When using cfhttp, you could always use cfif findNoCase(200, cfhttp.statusCode) to test for success. How is it done with xmlParse? I'd rather not use a cftry/cfcatch block. Why?

RE: Failing gracefully when using xmlParse()...
OK. Just thought there might be some flag in the xmlparse function that might say there was a connection problem. -Original Message- From: Dave Watts [mailto:[EMAIL PROTECTED] Sent: Friday, February 29, 2008 2:15 PM To: CF-Talk Subject: RE: Failing gracefully when using xmlParse()...

RE: Failing gracefully when using xmlParse()...
Knew that. Thought xmlparse had something similar baked into it. -Original Message- From: Ben Doom [mailto:[EMAIL PROTECTED] Sent: Friday, February 29, 2008 2:09 PM To: CF-Talk Subject: Re: Failing gracefully when using xmlParse()...

RE: Failing gracefully when using xmlParse()...
Yup. I hear ya. I just thought I might be able to write a few less lines of code. :) No biggie... -Original Message- From: Brad Wood [mailto:[EMAIL PROTECTED] Sent: Friday, February 29, 2008 2:17 PM To: CF-Talk Subject: RE: Failing gracefully when using xmlParse()... Xmlparse assumes that any preliminary checks and validations have been performed and that the string being passed in is well-formed XML. I can see what you are saying, but xmlparse could receive its input from absolutely anywhere so it wouldn't really work very well for xmlparse to try and catch those errors. The onus is on the programmer to ensure they have well-formed XML before they knock on xmlparse's door. ~Brad ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:300224 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

If you want to do something differently then the generally accepted way to do something, then it would help to know the reason you desire to buck the general consensus? I've not played with cffeed can it work off of a cfhttp result, allowing you to use the 200 status? ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:300222 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
