Regular expression not to match windows#
Windows (?=95|98|NT|2000) matches Windows in Windows 2000 but not Windows in Windows 3.1 Lookaheads do not consume characters: after a match occurs, the search for the next match begins immediately following the last match, not after the characters that comprised the lookahead. This is a non-capturing match, that is, the match is not captured for possible later use. Positive lookahead matches the search string at any point where a string matching pattern begins. Industr(?: y|ies) is a more economical expression than industry|industries This is useful for combining parts of a pattern with the "or" character (|). Matches pattern but does not capture the match, that is, it is a non-capturing match that is not stored for possible later use. To match parentheses characters ( ), use '\(' or '\)'. The captured match can be retrieved from the resulting Matches collection, using the SubMatches collection in VBScript or the $0$9 properties in JScript. Makes the remainder of the regular expression case insensitive. To match any character including the '\n', use a pattern such as ''. Matches any single character except "\n". When this character immediately follows any of the other quantifiers (*, +, ?, matches the first three os in fooooood Matches the preceding character or sub-expression zero or one time.Ĭolou?r matches color or colour but not colouur Matches the preceding character or sub-expression one or more times. Matches the preceding character or sub-expression zero or more times. If the RegExp object’s Multi-line property is set, $ also matches the position preceding '\n' or '\r'.Ĭat$ matches any string that ends with cat Matches the position at the end of the input string. If the RegExp object’s Multi-line property is set, ^ also matches the position following '\n' or '\r'. Matches the position at the beginning of the input string.
