Okay, I can live with that. But normalizing an SRE is not a matter of normalizing the strings in the SRE: indeed, that will break it. So at the very least I think a normalize-sre procedure must be provided that takes an SRE and does the nitty-gritty of selectively expanding charsets into disjunctions of sequences. That would not be incompatible with PCRE, because its effect is global. -- John Cowan http://www.ccil.org/~cowan cowan@xxxxxxxx I Hope, Sir, that we are not mutually Un-friended by this Difference which hath happened betwixt us. --Thomas Fuller, Appeal of Injured Innocence (1659)
