I am having problems reformatting a string. I want stick the Operational
Attrbute "employeeID" in a local variable. But I cannot find a regex
expression to do this proplery.

The employeeID is: name##(##########)
example: fred12(1234567890)

fred12 can be any alpha-numeric. The employeeID is always 10 digits between
the (). I cannot get rid of the last ).

<do-set-local-variable name="employee-number" scope="policy">
<arg-string>
<token-replace-all regex=".+\(" replace-with="">
<token-op-attr name="employeeID"/>
</token-replace-all>
</arg-string>
</do-set-local-variable>
