Elements in Strings
String standard library provides a number of functions for
manipulating elements in a string. In WMLScript, a string can be
broken into different substrings using a delimiter and each of these
substrings is called an element. This is illustrated in the following
example. Let's consider the string below:
tutorials: WML tutorial, WMLScript tutorial"
the comma is specified as the delimiter, then there are two elements
in the above string:
tutorials: WML tutorial"
" WMLScript tutorial"
the space character is specified as the delimiter, then there are six
String standard library provides five functions to help us manipulate
elements in a string. The five functions are:
five functions can also be used to simulate arrays in WMLScript. You
can learn how this can be done in the "Arrays
in WMLScript" section shortly.
