[Mono-devel-list] RFC: how to manage almost duplicate parser/tokenizer

[Atsushi Eno]

Hi,

I wonder which is the best way to have "almost duplicate" but
different parser/tokenizer pair for XSLT "Pattern" apart from
XPath (I'm going to fix a bug that allows improper XPath for
XSLT pattern e.g. namespace::*).

With my way to do, they could be generated by attached patches:

  $ patch -i pattern-parser.diff System.Xml.XPath/Parser.jay -o
    System.Xml.XPath/PatternParser.jay
  $ patch -i pattern-parser.diff System.Xml.XPath/Tokenizer.cs -o
    System.Xml.XPath/PatternTokenizer.cs
  $ patch -i use-pattern-parser.diff

... but I wonder if there are better ways to do handle those
parser/tokenizer stuff, because parser/tokenizer patches are easy
to become broken when we fix XPath parser and/or tokenizer sources.

Would it be better if I just put another parser/tokenizer pair?
