Hello,
Welcome to the wonderful world of feeds!
When adding feeds in xFeed, most sites will do fine by just typing the main url to the site ie:
http://www.sacbee.com/rss/ will be more than sufficient. xFeed will find all the feeds that the site has set up to be "autodiscovered."
However, for a site such as that one, with many feeds, It would be too cumbersome to have all of their feeds set up to be autodiscovered. In this situation there is more than one way to add the desired feeds.
For this particular site each sub-division has a different autodiscover feed. For example
http://www.sacbee.com will have the main features feed. Whereas the
http://www.sacbee.com/entertainment will have the entertainment feed set to autodiscover. So for example you wanted to add the feeds for business you would type
http://www.sacbee.com/business into the search for feeds box.
There is also another way to add the feeds. If when browsing the sacbee.com site from safari on your iPhone or iPod Touch you navigate to
http://www.sacbee.com/rss. On this page you have an expansive list of feeds. If you were to click on the feed of your choice that feed would open up in the default safari feed reader. From that page in safari you can load the feeds into xFeed by making one simple change in the address bar. Once a feed is opened in safari the url in the address bar will be changed to
http://reader.mac.********* all you have to do is navigate to the
farthest left of the address bar and change the http:// to xfeed:// and xFeed will automatically open and add your feed.
