First of all, you should use the document that you want to insert the 
nodes in as 'targetDocument'. That way you don't need to call 
.importNode on each of the nodes in the resulting fragment. That is the 
whole point of being able to specify a target document.

To answer your question though, there are some tricky security stuff wrt 
about:blank documents, do you see any errors in the error console?

Since it sounds like you are getting the result you are expecting from 
the XSLT transform, you're just then having problems displaying those 
nodes, this is likely not an XSLT related problem.

It would be good if you could provide a minimal testcase to see what 
you're trying to do.
