Re: [HTCondor-users] help on classAd regexp

[Stefano Belforte <stefano.belforte@xxxxxxx>]

well.. FWIW that was checking for 3 colons or more, not exactly 3.
After a couple of "sorry Claude, it still fails", finally it gave me this, which appears OK
 regexp("^((?!T1).)*T1((?!T1).)*T1((?!T1).)*$", DESIRED_SITES)

i.e. sort of like "^.*T1.*T1.*$"  but with the constrain that
those ".*" does not contain (T1), IIUC.
