Well, but .... (there is allways a 'but') :-)
Suppose I do not subclass XML::Parser.
But then, how do I pass parameters to XML::Parser handler methods
and collect results of their run without using global
variables of XML::Parser package? Only class that I get
to handler methods is expat itself and there is no place for
any aditional parameters/results of handler methods.
And if I subclass XML::Parser, only advantage that I gain is
using my own package namespace for global variables instead
of XML::Parser's namespace. This do not looks to me like a good
example of object oriented programming style.
Possible silution is the one mirod suggested using Non-Expat-Options
but it is just a little bit less ugly than these two.
There best solution will be forcing XML::Parser to use
my custom subclass of XML::Parser::Expat instead of XML::Parser::Expat itself.
Is there some way how to do that?
