I don't believe regexp supports lookahead or lookbehind assertions. You'd need to use jakarta-oro for that. However, I don't understand why ^abc.xyz$ doesn't do the job for you in this case since you're asking for an exact match. Unless you really mean for it to be okay for non-word characters to follow the string. daniel --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
