Hello, I was wondering which tool people use to validate their regular expressions?
I was going throught some of the templates I found in the web and found one with following regular expression: (?s:^.*$) When using http://www.regexr.com/ which I find very good and complete, regexr.com tells me that the question mark at the beginning is invalid? So which way do you write or validate your expressions? Tks for feedback. Uwe
