http://issues.apache.org/bugzilla/show_bug.cgi?id=27763 Incorrect reluctant matching when they contain another quantifiers Summary: Incorrect reluctant matching when they contain another quantifiers Product: Regexp Version: unspecified Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Other AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I've tried to match 1__ line against ^(1_*)??_$, ^(1_*)*?_$, and ^(1_*)+?_$ In all cases I get negative answer. But ^(|1_*)_$ (which is the same as last one) matches the string. As far as I understand the cause of this problem is that we use OP_RELUCTANTXXX for these quantifiers and process them incorrectly. Perhaps we should do the same as for greedy quantifiers, i.e. replace X?? by (|X), X+? - XX*?, and X*? by (|X{gotoX}) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
