Re: cfhttp/xml help
For anyone who's interested, I've blogged the considerations/issues I ran into (or can remember running into) when using ColdFusion to consume a feed at http://musetracks.instantspot.com/blog/index.cfm/2007/3/18/Consuming-an-RSS-Feed-with-ColdFusion. A follow-up post will detail the issues I had when displaying the content of a feed.

Re: cfhttp/xml help
@Bob & Randy - I cracked open some of my code and, if I was looking in the right place, this is what I did... This code strips out any character (printing or non-printing) that occurs before the opening "<". In a valid feed, that opening "<" would mark the start of "". Hope this helps.

You may have non-printing characters. I've seen this before as well and I've solved it, but I can't remember how. I'll try digging up some of my old code and see if I can be some help.

Re: cfhttp/xml help
Hi Bob, I had this happen with a couple rss feeds. I tried trimming the feed in case of any white space. That did not help it so I finally gave up. The weird thing is, the feeds worked fine if I put them in the RSS Reader. I currently use GreatNews for My RSS reader. I did some testing with online rss validators on the url in your example, it was to big for the online validators to check but It did pass the xml validator test (Well Formed), so I assume it is a valid rss feed too.

cfhttp/xml help
Hi Folks, I'm just getting started with learning the basics on pulling xml feeds with cfhttp and am in need of some help with an error I get with some feeds I'm playing with. Here's the code block I'm working with and I get the following error on this feed and a couple of others... Content is not allowed in prolog. The error occurred in C:\Inetpub\wwwroot\testing\rss.cfm: line 10 8 : 9 : http://www.nranews.com/rss/rss.xml"; method="GET" resolveurl="No" > 10 : http://www.nranews.com/rss/rss.xml"; method="GET" resolveurl="No" > Title: #MyXML.rss.channel.item[x].title.xmlText# click here #MyXML.rss.channel.item[x].description.xmlText# While this same block of code works fine using the feed from http://www.tfc.edu/radio/podcasting/music.xml I'm confused here, any help in understanding this is appreciated!
