You may need to view source for that, but there are ways to view source on iOS browsers that don't have it built in according to http://osxdaily.com/2012/03/30/view-source-safari-ipad-iphone/ - or someone could do it on a computer and post the information.
Dreamwidth has rss following capability - feeds can be added on the read / feeds page at https://www.dreamwidth.org/feeds/
