Subject: Regular expression extractor -- regex modifiers? 


Hi: I hit a problem with the JMeter Regular Expression Extractor. 

>From a HTTP response, I need to extract text which occurs after some
"marker". The problem is that this "marker" occurs several lines before the
text.  So I need to do a multi-line match. 

For e.g.: to extract out the value of url="..." (which occurs below
"MARKER"):
------------------------
url="..."
...
url="..."
...
MARKER
...
url="<extract me please>"
------------------------

I set the JMeter regex extractor to: 
        MARKER.+?url=\"(.+?)\"
But this does not match because there are newlines between MARKER and the
text to extract.


In Perl, I am able to append a '/s' modifier to the same regex:
        /MARKER.+?url=\"(.+?)\"/s
This works because it forces Perl to treat the regular expression in
multi-line string mode. From "perldoc perlre": 
-------------------------------------------------------------------
       s   Treat string as single line.  That is, change "." to
           match any character whatsoever, even a newline, which
           normally it would not match.
-------------------------------------------------------------------


Is there a way to force the JMeter regex extractor to take Perl-like regex
modifiers?

With regards,

PS: Right now, I have a nasty workaround. I set the regex to ignore either
normal or newline characters:
        MARKER(.|\r|\n)+?url= \"(.+?)\"
...and I use $2$ instead of $1$.
