Comment:

 SimpleXML actually seems to support namespaces. If you add some calls to
 $xml->registerXPathNamespace() it prevents the "does not appear to be a
 WXR file" message from appearing. And then if you update the namespaces it
 actually imports content (the 1.2 namespaces are what are currently
 produced by WordPress' built-in exporter).

 Here's a patch:

 (This may or may not break importing from XML using the 1.1 namespaces, I
 haven't tested).
