You should also be able to use expressions of the form
\d{8}
There is some discussion of Regexes in the JMeter FAQ with pointers to
further information - see
http://wiki.apache.org/jakarta-jmeter/JMeterFAQ
I've started a page on Regular Expressions:
http://wiki.apache.org/jakarta-jmeter/RegularExpressions
Feel free to update with some examples.
