Expand the properties, recursing only once
Given a <response><href>...</href><propstat><prop><someprop/></prop><status>HTTP/1.1 200 OK</status></propstat>...</response> pull out the content of <someprop>content</someprop> and check to see if it has any href elements. If it *does* then recurse into them, looking for the next deeper nesting of properties.
