[xml] nbParse* variables

[Mike Hommey <mh glandium org>]

Hi,

In parser.c there are 5 nbParse* variables that are only used in
parser.c, but are still exported as symbols. Is that really necessary?

They don't even seem useful at all, the only places they are used is to
do nbParsexxx++, with no other place where the variables are read...
