list.countOccurrencesOf(literalStr)
This function returns the Number of times that the literal string literalStr appears in the source List- or Set-type list. A string of the attribute's raw concatenated list values (i.e. with semicolon delimiters) is tested.
If $MyList contains "ant;bee;ant;cow;ant", then:
$MyNumber = $MyList.countOccurrencesOf("ant"); returns 3Sets de-duplicate, but partial matches of Sets do not. If $MySet contains "cat;cut;hat;hit;hut;pat;sat", then
$MyNumber = $MySet.countOccurrencesOf("at"); returns 4literalStr is literal and must not be a regular expression. If the latter is needed use list.contains() or list.icontains().
