Hello,

I want to include named character class [[:xdigit:]] as a part of another user defined character class.

I am not getting the desired results. Pl. find my test example attached.

Please let me know how to do this.

If you want to include both xdigit and "x" in the class then use: [x[:xdigit:]] You had too many [['s in the expression. HTH, John.
