Not a a problem, that's how XML and Xpath work ;-) In the document xml
view (which is what is used for Xpath queries), all your provider
nodes have the same name "provider", hence
/jcr:root/root/providers/provider matches multiple elements.

Yes, see http://www.day.com/specs/jcr/1.0/

However, with same-name siblings you will see this problem in various
places, so I strongly recommend to change your content model and give
those SNS a distinctive name (eg. name of the provider, date, or even
some id if it is common). How do you know the first provider is the
right one anyway?
