Extracting multiple substrings from a text string

I think you can jusy repeat this like 20 times.  This one does the first two.  You can just repeating the pattern.

var text StringOneStart = NotLeft([Stp String], Find([Stp String],"stp")-1);
var text StringOne = Trim(Left($StringOneStart, "|"));

var text StringTwoStart = NotLeft($StringOneStart, Find([Stp String],"stp")-1);
var text StringTwo = Trim(Left($StringOneStart, "|"));

List(", ", $StringOne, $StringTwo)
