Bug #9369: Using XMLScanStreamParser in xmlrpc/parser may result in parse errors

I've tried to use the attached script to test if the XMLScanStreamParser would be a suitable alternative for REXMLParser (which often results in out-of-memory-errors when using large data chunks). Unfortunately, using this parser results in other errors:

  /usr/lib/ruby/1.9.1/xmlrpc/parser.rb:747:in `on_stag_end': wrong number of arguments (3 for 1) (ArgumentError)

The code calling on_stag_end in xmlscan/parser.rb is quite simple:

  def on_stag_end(name, *a)
    @visitor.on_stag_end name, *a
  end

The following should probably fix this (although I've got no idea if this has any side effects):

  - def on_stag_end(name); end
  + def on_stag_end(name, *a); end

An alternative solution might be to remove the definition of on_stag_end completely, that will result in a call to method_missing, which doesn't do anything either.
