Can I load the data into a custom object using a RSS feed provided by an external vendor?
Is there any kind of parser/a method that will consume the RSS and let me fetch data from external service?
Please help!!!
I do this currently to track some posts on DFC. I created a gist here:
https://gist.github.com/3982587
Which is the core class. It adds data if there is no matching custom object in the system. I schedule it to hit three times a day, and then there's a util class which sends out an email to let people know new blog posts have arrived.
There's XML parser and the HttpResponse class can deal with JSON as well as XML.
Ron Hess has built a slick parser and shared it on developer.force.com: http://developer.force.com/projectpage?id=a0630000002ahp8AAA
Check these out.
My Developer Edition came with built-in XMLDom
class. Probably it's their standard code (no idea if I can post it here) but it's kind of crude (from 2007).
