StringsubstringBetween(String str, String pos1, String pos2)
substring Between 
int p1 = str.indexOf(pos1);
String sub = str.substring(p1 + pos1.length());
int p2 = sub.indexOf(pos2);
sub = sub.substring(0, p2);

StringsubstringBetween(String str, String tag)

Gets the String that is nested in between two instances of the same String.

A null input String returns null . 

return substringBetween(str, tag, tag);
StringsubstringBetween(String str, String tag)
substring Between 
return substringBetween(str, tag, tag);
