"RegExp" Class and Object for Regular Expression Support

This section describes the 'RegExp' class and objects used for pattern matches using regular expressions. oRegExp.execute(string) returns a MatchCollection collection object.

VBScript supports a built-in class called "RegExp" to provide regular expression support.

In order to perform a regular express task, you need to create a RegExp object with this syntax:

   Set oRegExp = New RegExp

Note that we have to use the "Set" statement to assign an object to a variable.

Then we are ready to use properties and methods supported on the RegExp object, oRegExp:

The Match object has the following properties:

Notice that MatchCollection and SubMatches objects are collection objects. They share same properties and methods as all collection objects. See the next section for details.
