How can I create a URI from an xml data?

Question

I'm trying to create a simple right-click to a html link and then 'save as' and saving the xml data... the url looks something like this:

http://dailymed.nlm.nih.gov/dailymed/services/v2/spls/1a665e64-9f30-be37-4a83-38789f1f1e89.xml

Note: For some reason the browser does not display the xml I can only view it on the source (I know most modern browsers display the xml tags)

I tried something like this:

var uri = "data:application/xml;charset=UTF-8," + encodeURIComponent(xmldata);

But this has not worked out.. I have searched on this topic but had no success. Any help? thanks
