And I've posted a follow-up http://blog.stevenlevithan.com/archives/es3-regexes-broken here (which in truth is more of a long rant). BTW, here's another variation on the use of Perl-style group participation handling that I posted on a regex forum yesterday: http://regexadvice.com/forums/permalink/25764/36926/ShowThread.aspx#36926 Reg Expression for matching [multiple required attributes] (that regex also uses an atomic group, but that's not imperative in this case and can be emulated even in ES3 by using capturing groups in lookahead, if necessary). The Perl-style handling is intuitive and ripe for creative exploitation. The ES3-style handling is essentially useless. But I'll stop beating this horse now... -- View this message in context: http://www.nabble.com/Regex%3A-How-should-backreferences-contained-in-the-capturing-match-they-reference-to-work--tf4367560.html#a13964984 Sent from the Mozilla - ECMAScript 4 discussion mailing list archive at Nabble.com. _______________________________________________ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss
