Test Method (VBScript)
Updated: March 2009
Executes a regular expression search against a specified string and returns a Boolean value that indicates if a pattern match was found.
The actual pattern for the regular expression search is set using the Pattern property of the RegExp object. The RegExp.Global property has no effect on the Test method.
The Test method returns True if a pattern match is found; False if no match is found.
The following code illustrates the use of the Test method.
Function RegExpTest(patrn, strng) Dim regEx, retVal ' Create regular expression. Set regEx = New RegExp regEx.Pattern = patrn regEx.IgnoreCase = False ' Do the search test. retVal = regEx.Test(strng) If retVal Then RegExpTest = "One or more matches were found." Else RegExpTest = "No match was found." End If End Function MsgBox(RegExpTest("is.", "IS1 is2 IS3 is4"))
