Special group of functions for NON-ELEMENT nodes in document

OK. I am now convinced that W3C does the best thing.

I was only questioning why some browsers considers only the
elements 
inside (I tested an example in a BAD browser that is I.E.
and a little 
better one, that is Opera).
Those two didn't return the textnodes...

But one member (Joćo Eiras)  here gave me a good hint: to
use 
rows[y].cells[x]  as  my problem began while processing
tables with 
javascript.

For me, this topic is ENDED. Thanks for all advices.
