Regular expression validator

[Steve Vangasse]

Is there a way to get the tr:validateRegExp validator to run in 
Pattern.DOTALL mode so that the . character matches any character, including 
a line break. I need to validate that a text area contains a specific string 
amongst surrounding text that can include new lines. I tried using the 
embedded flag expression (?s). in the pattern but I just get a javascript 
error on the page: "Syntax error in regular expression".

Has anyone else tried this
Thanks,
