Splitting the String

If anybody wants to copy & paste, this is my approach .

I did it a bit differently, because the original approach assumes that your split character is only 1 character long and that there is never a split character at the end of the string. (In the first case, that would leave you with the rest of your split character in the next line; in the second case, it would leave you with an extra line in the result.)

My import variables are:

IV_STRING : AP.Common.GDT::LANGUAGEINDEPENDENT_EXTENDED_Text;
IV_SPLIT_AT : AP.Common.GDT::LANGUAGEINDEPENDENT_EXTENDED_Text;

Also, the reuse function should be read-only so it can be used cross-deployment unit.

import ABSL;
import AP.Common.GDT;
// takes the import string IV_STRING and returns a list of strings that was split
// at the IV_SPLIT_AT character
var result : collectionof DataType::LANGUAGEINDEPENDENT_EXTENDED_Text;

// this converts IV_SPLIT_AT to "String" data type (otherwise there's an activation error)
var split_at = IV_SPLIT_AT;

var length_at = split_at.Length();

// 1) if any of the strings are empty, return an empty result
if (IV_STRING.Length() == 0 || length_at == 0)
{
	return result;
}

// 2) go through the string and split it
var start = 0;
while (true)
{
	// check if start is out of bounds
	// find next match
	var pos = IV_STRING.Find(split_at, start);

	// no further occurence found?
	if (pos == -1)
	{
		
		// check if any characters remain at end of string
		if (IV_STRING.Length() > start)
		{
			var remainder = IV_STRING.Substring(start);
			result.Add(remainder);
		}

		// abort loop
		break;
	}

	// otherwise add found string to result
	var sub_length = pos - start;
	var substring = IV_STRING.Substring(start, sub_length);
	result.Add(substring);

	// set new start position for next loop
	start = pos + length_at;
}

// 4) return result
return result;

Kind regards
