17.6. Manipulating Elements in Strings
The 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:
"WAP tutorials: WML tutorial, WMLScript tutorial"
If the comma is specified as the delimiter, then there are two elements in the above string:
"WAP
tutorials: WML tutorial"
" WMLScript tutorial"
If the space character is specified as the delimiter, then there are six elements:
"WAP"
"tutorials:"
"WML"
"tutorial,"
"WMLScript"
"tutorial"
The String standard library provides five functions to help us manipulate elements in a string. The five functions are:
elements()
elementAt()
insertAt()
removeAt()
replaceAt()
These 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.
