Your example has no netloc. From the Python docs:

"recognizes a netloc only if it is properly introduced by ‘//’. 
Otherwise the input is presumed to be a relative URL and thus to start 
with a path component."

urllib does not support xmpp:

"The module has been designed to match the internet RFC on Relative 
Uniform Resource Locators. It supports the following URL schemes: file, 
ftp, gopher, hdl, http, https, imap, itms-services, mailto, mms, news, 
nntp, prospero, rsync, rtsp, rtsps, rtspu, sftp, shttp, sip, sips, 
snews, svn, svn+ssh, telnet, wais, ws, wss."
