Thanks for all the feedback, 
I understood Vlads point, eventually. (Now I only need to understand how to
use his function :-).
The reason why I like the idea about one single pass was that I had a vague
idea of using xmerl + yaws to export/publish XML documents written in the
Simplified DocBook DTD on the fly. So I was i bit biased towards performance.
Given all the earlier >1000/s dynamic pages yaws could do, I just thought it 
could be nice to have a real "heavy duty" engine for XML transform and 
publishing. I'll give it a second thought though, fast is not always 
correct...
