Comment (by pbiron):

 I think the underlying problem here is also preventing me from writing
 unit tests for export.

 I'm trying to have something like the following in a unit test:

 {{{#!php
 ob_start();

 export_wp();

 $wxr = ob_get_flush();
 // $wxr should now contain the exported XML as a string
 }}}

 When `export_wp()` calls `header(...)` an exception is raised because
 "headers already sent".

 Does anyone have a work around that I could use to get the output of an
 export?
