For length including white-space       id   val   length    For length without white-space       id   val   replace    g     length   For removing only beginning and trailing white-space     trim     test   val    length   For example  the string   t e s t   would evaluate as       t e s t       id   val        Example 1     id   val   length    Returns 9   Example 2     id   val   replace    g     length    Returns 4   Example 3   trim     test   val    length    Returns 7   Here is a demo using all of them
