Fix RSS feed parsing due to changes in go-pkg-xmlx.

Browse source 
Due to the PR jteeuwen/go-pkg-xmlx#16, when using SelectNodes there is no
longer any hidden recursion.  Due to RSS's structure, there is a root document
node.  These two pieces break the RSS parsing.  Fix by first selecting the
root document node, and then selecting the channels for parsing.
