Re: Difference between these regexes

[haukex]

Thank you very much, everyone who replied!

Taking all the replies together I think that confirms that the set of strings matched is the same for all three of these particular regexes.

This also confirms my initial suspicion that the regex m{<ReportHost[^>]*>(?:(?!</ReportHost>).)*</ReportHost>}s could also be written as m{<ReportHost[^>]*>.*?</ReportHost>}s.

There are many ways and tools to figure out a regexp. One of them is: http://www.regexr.com/ imho. You can mouse over the regexp to see what it's looking for, and in the result panel you can see the range, group, etc. You might want to try it for the next quest.
