Hi,
Ive been getting there with this Sax buisness...
Now my handler class is on the way (the problem I had earlier is sorted)
However How do I make comparisons efficently using SAX...I mean when it get
the tag, i need to compare it & find the right variable to assign the
character data too (the data between the tags)
I would add to my handler class an instance of type XMLStringPool,
initialize it by adding to it the names I am interested in (using
addOrFind), then use getId to convert the node name into one of these
known ids.

Cheers
