 This plugin doesn't understand namespaces when parsing XML.

 Correct me if I'm wrong but I think the following XML documents are
 equivalent:

 {{{
 <rss xmlns:wp="http://wordpress.org/export/1.2/">
   <channel>
     <wp:wxr_version>1.2</wp:wxr_version>
   </channel>
 </rss>
 }}}

 {{{
 <rss>
   <channel>
     <wxr_version
 xmlns="http://wordpress.org/export/1.2/">1.2</wxr_version>
   </channel>
 </rss>
 }}}

 {{{
 <rss>
   <channel>
     <wp:wxr_version
 xmlns:wp="http://wordpress.org/export/1.2/">1.2</wp:wxr_version>
   </channel>
 </rss>
 }}}

 {{{
 <rss xmlns:ns1="http://wordpress.org/export/1.2/">
   <channel>
     <ns1:wxr_version>1.2</ns1:wxr_version>
   </channel>
 </rss>
 }}}

 Importing the first document leads to the next step with the "Download and
 import file attachments" checkbox and the "Submit" button. The other
 documents produce "This does not appear to be a WXR file, missing/invalid
 WXR version number".

 This bug makes it difficult to write tools which generate WXR files (for
 instance when migrating content from an existing site into a WordPress
 installation).
