Extracting the text of a specific XML node

I have to extract friendlyName from the XML document.

Here's my current solution:

root = ElementTree.fromstring(urllib2.urlopen(XMLLocation).read())        
for child in root.iter('{urn:schemas-upnp-org:device-1-0}friendlyName'):
    return child.text

Is there any better way to do this (maybe any other way which does not involve iteration)? Could I use XPath?

XML content:

I am going to assume you are using Python's built-in XML library.

There are some basic XPath functionality implemented into Python's XML library. Using XPath and the find() function:

import xml.etree.ElementTree as ElementTree

namespace = '{urn:schemas-upnp-org:device-1-0}'
root = ElementTree.fromstring(urllib2.urlopen(XMLLocation).read())

# The `//` specifies all subelements within the whole tree.
return root.find('.//{}friendlyName'.format(namespace)).text

The find() function stops when it finds the first match. If you wanted to get all of the elements that match the XPath, use the findall() function.
