Regular Expressions¶
Purpose¶
A regular expression is a sequence of characters that defines a search pattern for strings. It is composed of character literals and special characters. Each character literal represents a single character (such as "a", "b", "C", "1"). Special characters can represent a character, multiple characters, or define choices for matching characters.
Usage¶
In Rapise, you must prefix regular expressions with the string regex:. For example, the regular expression to match all strings is: regex:.*
Regular expressions have three uses in Rapise: (1) in Object Locators, (2) in action overriding code, and (3) in Custom Libraries.
Examples¶
Within an Object Locator to match a dynamic Window Title:
regex:.*Microsoft Dynamics NAV matches any Window Title ending with Microsoft Dynamics NAV, for example:
1 | |
or
1 | |
