So a list of n characters will have n+1 empty strings. Before, and after each character, there's an empty string. If the DOT-ALL modifier is not available, you can mimic the same behavior with the character class : /^((?!hede))*$/Ī string is just a list of n characters. (where the /./ are the regex delimiters, i.e., not part of the pattern) As mentioned, this is not something regex is "good" at (or should do), but still, it is possible.Īnd if you need to match line break chars as well, use the DOT-ALL modifier (the trailing s in the following pattern): /^((?!hede).)*$/s The regex above will match any string, or line without a line break, not containing the (sub)string 'hede'. You can mimic this behavior by using negative look-arounds: ^((?!hede).)*$ var GivenDate = '' var CurrentDate = new Date () GivenDate = new Date (GivenDate) if (GivenDate > CurrentDate)", str) for s in all: print(s) resultĤ.4.The notion that regex doesn't support inverse matching is not entirely true.
You can easily compare the date with current date The following example code checks whether given date is greater than current date or today using with new Date() in JavaScript. How to Check Given Date is Greater than Today using JavaScript, Date validation is very useful when you want to restrict the user to provide a future date. NET finction getdate() to acquire todays date then compare it programmatically with the date from user's input. I have aĭate now greater than date value given, How to Check Given Date is Greater than Today using JavaScript, Compare date with Regular Expression for greater than date format xx-xx-xxxx, It probably no, it's not possible with regex, b/c regex does not have a conceipt of time it can only validate patterns, and as u realize the patterns of today's and yeasterday's dates will be identical. Ask Question Asked 8 years, 10 months ago. This assumes all dates are Regular Expression for greater than date format xx-xx-xxxx.
Regular Expression for greater than date format xx-xx-xxxx, It probably shouldn't be done, but it can be done: (|1)-10-2011|-1-2011|-201. What would be regular Expression for validating Date format like mm/yyyy.? Regular expression check date greater than today
