<@REGEX EXPR="[[:alnum:]]+" STR="abc5 defgHijklm;no p4qrstuv)0wx,yz"
TYPE="E" position=all>

will return:

      abc5 1 4 1
      defgHijklm 6 10 2
      no 17 2 3
      p4qrstuv 20 8 4
      0wx 29 3 5
      yz 33 2 6


thus:

<@REGEX EXPR="[^[:alnum:]]+" STR="abc5 defgHijklm;no p4qrstuv)0wx,yz"
TYPE="E" position=all>
will return

     5 1 1
      ; 16 1 2
     19 1 3
      ) 28 1 4
      , 32 1 5



(If the string in question is alphanumeric the number of rows in the second
array should be zero)...

If I can be of further assistance please contact me.
