VBS Tutorial: Method-test Method _vbs

Test method

object.Test(string)

Parameters

Object

Required option. Always the name of a RegExp object.

String

Required option. The text string to perform a regular expression search for.

Description

The actual mode of the regular expression search is set by regexp the Pattern property of the object. The Regexp.global property has no effect on the test method.

The test method returns true if a matching pattern is found, otherwise it returns false.

The following code illustrates the use of the test method.

  Function regexptest (patrn, strng) Dim regEx, retval              '  to establish a variable. The  set regEx = New regexp          '  establishes a regular expression.  Regex.pattern = patrn          '  setting mode. The  regex.ignorecase = false          '  setting is case-sensitive.  retVal = regex.test (Strng)                '  to perform a search test.  If retVal Then   regexptest =  finds one or more matches.    Else   regexptest =  did not find a match.    End If   End Function   MsgBox (Regexptest ("is.", "IS1 is2 IS3 is4"))
