That's an exercise in applying string functions:

im have a similar enigma here as well. Trying to omit dashes in a key id. Is there a workaround for this?

I didn't quite see anything on the lslwiki. Any help will do thanks!

AFAIK, there is no magic for your string problem. You'll have to extract each letter from your string and check if they are valid or not.

For the stripped key, there's a simple trick:

string stripped = (string)llParseString2List((string)id, ["-"], []);

CODE

integer counter = llListLength( a );
while (counter){
  --counter;
  if (!~llSubStringIndex( b, llGetSubString( a, counter, counter ) )){
    a = llDeleteSubString( a, counter, counter );
  }
}

might want to use llToLower (or Upper) to make sure you don't catch x when only X appears in string b
