(?s)sam.*e
will do what you want. "s" is for "treat as Single line".
You can also use the other modifiers ("m" for "treat as Multiple lines", "i" for "Ignore case", and "x" for "eXtended legibility") in the same way. You can combine them:
(?si)sam.*e
will match « Sam Uncle » for example.

Thanks, everyone, for your responses. I really appreciate your assistance.
I'm looking into the m and the s modifiers and I'm
having some difficulties using them in Response
Assertions. For example, if my response is an HTML
page with exactly 8 occurrence of the word "sample", I
am able to use a Response Assertion to match the
pattern
sam.*e
But it fails if I change the pattern to
m/sam.*e/
According to the Perl textbook I'm using, the m modifier is optional when the slashes are used. So, shouldn't the pattern m/sam.*e/ produce the same results as sam*.e ?
Am I using the m modifier incorrectly? Is the reason that m/sam.*e/ doesn't work in the Response Assertion because the regular expression is sam.*e and the m modifiers and the slashes are modifiers/delimiters and not really part of the regular expression (so don't belong in the Response Assertion)?
Please let me know if I've got a basic
misunderstanding someplace. But, as I see it so far,
the patterns in the Response Assertion will only match
on a one-line-at-a-time basis and are not used to
match the response as a whole.
Thanks very much.

One could try anchoring the last sample:
(sample.*){7,7}(sample.*$){1,1}
but I think that would suffer from the same problem as the negative look-ahead. It may be tricky stopping the matcher from working its way past the leading samples.

Also,
(sample.*){8,8} will match exactly 8 occurrences.

JMeter uses Jakarta ORO
(http://jakarta.apache.org/oro/index.html) to
implement Perl5 patterns.
Since Perl includes multi-line patterns using the
"m" and "s" modifiers:
<quote from Perlre document> m
Treat string as multiple lines. That is, change
``^'' and ``$'' from
matching the start or end of the string to
matching the start or end of any
line anywhere within the string.
s
Treat string as single line. That is, change ``.''
to match any character
whatsoever, even a newline, which normally it
would not match.
</quote>
It looks as though "s" might be best in your case.
As a start, you could try matching sample 8 times
using something like:
(sample.*){8} This would eliminate fewer than 8 occurrences.
(sample.*){9} should catch ones with 9 or more.
So you could use two assertions; the first to
match 8 samples, the second to
NOT match 9.
The tricky bit would be combining the two, as
(sample.*){8}(?!.*sample)
would presumably be happy to match 9 occurrences
by starting the match with
the second sample.
I'm afraid I'll have to leave solving that as an
exercise for the reader, as
I don't know how myself.
I could not find anything on the ORO pages about
exactly what REs it
supports, or if there are any exclusions.
Perl itself has pretty good documentation on
regular expressions. If you
have a Perl installation, try perldoc perlre,
perlrequick or perlretut.
There is online documentation on the Activestate
web-site and elsewehere.
Hope this will help you get started. If you find a
good solution, please
share it with us!

Currently, the Response Assertion only supports a
yes/no response
to whether the text includes the regex.
Supporting match counts
would be useful too, I think.

I've seen how an Assertion Results can report

whether or not it finds an occurrence of a
certain
pattern in a line. But can I use this feature
to, for
example, verify that my response is an html page
with
exactly eight occurrences of the word "sample"
within
a <pre></pre> tag somewhere in the body of the
page?
Am I limited to testing for only patterns
contained in
a single line?
Thanks very much.
