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.
