Isolating an RSS feed by topic (i.e., Blogger label)

I finally worked out how to get the RSS feed of just one label from Blogger. For example, the feed which just covers the label "Web" from this (http://notebook.raveem.com) would be:

http://notebook.raveem.com/feeds/posts/default/-/Web

For a long time, I couldn't get this to work until I fixed what was wrong with the url: the label (right at the end) is case sensitive! So /web doesn't work. /Web does.
