There is no error in using the selector, but it seems that the above 
pipeline is included into another one (that's why the error message 
talks about internal pipeline). It's difficult to say without seeing the 
rest of the sitemap. But replacing the reader with a generator and a 
serializer as suggested by Mark should work in every case. If the file 
is HTML and not XML, you need the HTMLGenerator and the HTMLSerializer.
