  I'm getting *REALLY* confused now. What are you trying to achieve ?

  Yes, by keeping track of them.

   I do NOT understand. Entity resolution is done at parse time.
I was thinking your routine was running on an already built tree.
So what on earth entity resolution has to do with your routine ?

  I said, I'm getting really confused about what you intend to do.
If you substitute entities you will get text, element, PI and CDATA
nodes as the tree replacement content. So why are you trying to remove
them. No really I can't understand.
