I built the RSS Reader example project from Javier Menendez’s excellent blog:
https://blog.xojo.com/tag/rss/
I got it up and running quickly. It worked exactly as described. Then I modified it to suit my needs. Basically, I want to receive various news feeds. I got that part working too, at least partially. It works fine for some news feeds, but for others, it fails to load the content.
These are the news feed URLs that I’ve been testing:
BBC Britain:
http://feeds.bbci.co.uk/news/rss.xml
http://feeds.bbci.co.uk/news/world/rss.xml
http://feeds.bbci.co.uk/news/science_and_environment/rss.xml
US Networks:
https://feeds.nbcnews.com/nbcnews/public/news
https://www.cnbc.com/id/100003114/device/rss/rss.html
http://feeds.abcnews.com/abcnews/moneyheadlines
https://www.cbsnews.com/latest/rss/main
CBC Canada:
https://www.cbc.ca/cmlink/rss-topstories
https://www.cbc.ca/cmlink/rss-world
https://www.cbc.ca/cmlink/rss-offbeat
ABC Australia:
https://www.abc.net.au/news/feed/4535882/rss.xml (rural)
https://www.abc.net.au/news/feed/51120/rss.xml (just in)
They all work except for the US Network feeds. However, if I open them in a regular web browser, then they all work (including US Networks). I’m trying to figure out why the US Network feeds refuse to work in the Xojo RSS reader. My guess is that they are expecting to see something like a User Agent string and aren’t getting it. I know how to set a user agent in an HTMLviewer control, but there doesn’t appear to be anything equivalent in an HTTPSecureSocket. Also, I added event handlers for authentication required, proxy authentication required, and error, but none of these are triggered.
Any ideas what the problem could be?
