Yeah, I wish this was easier than parsing XML since it's such a common
operation. A while ago I proposed something like this addition

 GetAllInterfaces (OUT a{sa{sv}} hash_from_iface_name_to_property_bag);

on the org.freedesktop.DBus.Properties interface that would give you
this information as well as allowing you to load all properties in one
go.
