BTW, since I mentioned .NET 2.0's character class subtraction syntax, I'll note that it actually comes from the W3C's XML Schema regex flavor, and is also used in the XPath flavor.
BTW2, I don't actually think it would make much sense to arbitrarily remove or limit a feature for the sake of arguably reduced parsing complexity. I was more just interested in if others had similar concerns. -------------------------------------------------- From: "Steve" <[EMAIL PROTECTED]> Sent: Saturday, December 22, 2007 10:40 PM > [...] it effectively makes it impossible to parse ES4 regex syntax > using ES4 regexes (which lack PCRE/.NET/Perl's recursion support).
