| I presume you mean, in any order, and that the other 5 characters are from the same group? I don't think you can do that in one regular expression, but you could go a fair way, and test the resulting string in a script. Something like this:
([A-Za-z0-9]{8,})
Then in a script use "instr" to confirm that you got one from each group you mention. |
