Example
In this example, we will pass the required parameters to the function transformation object using a Variables object.
Where,
Pattern = ^H[\S]{0,4}|$
String = HelloWorld!
Note: The specified regular expression will look for and match a string which begins with “H” (case sensitive). Next, it will match any character that is not a whitespace character in the next 0 to 4 characters. Finally, the “$” is used to end the string. Therefore, the returned output should be “Hello”.
In the output window, you can see that Astera has returned a string value, as the regular expression pattern has been matched.
