The regex is simply:

<value>(.+?)<
looking for the 16th match.  The default value is "unset"

From the performance aspect it might be worth trying

<value>([^<]+)

as this does not require lookahead.

This particular thread group has 10 threads.  over all there are about 550
in use.  The group itself has a read from csv, a counter, 2 samplers, the
2 regex's and finally a constant throughput timer.

OK.

I can already see the responses in our database.  AFAIKT there's no way
they  could be any different to what comes out at the jmeter end, but i'll
have a try.

Should not be different, but they are presumably at different ends of
a network connection, so it's remotely (!) possible.

It seems to fail completely - I get the "unset" (default value) which
doesnt appear in the xml response at all, rather than the wrong value.

Any error/warning messages in the jmeter log file?
