We have a UDF close to that - ListCompare - " Compares one list against
another to find the elements in the first list that don't exist in the
second list. Performs the same funciton as the custom tag of the same
name." However, I think you want this:
function existsInList2(l1,l2) {
var i = 1;
var newList = l1;
for(i=1; i lte listlen(l1); i=i+1) {
if(listFind(l2,listGetAt(l1,i)) newList =
listDeleteAt(newList,i);
}
return newList;
}
You would want to add support for dynamic delimiters of course. Several
examples at cflib.org show how to do this. I wrote this _very_ quickly,
so forgive any typos. You may also want to consider changing listFind to
listFindNoCase if you don't care about case. (Or even easier, make it
one more optional arg, and if you don't care, just ucase l1 and l2.)
