提供简单的正则表达式支持功能。
下面的代码说明了RegExp对象的用法:
Function RegExpTest(patrn, strng)Dim regEx, Match, Matches "建立变量。Set regEx = New RegExp"建立正则表达式。regEx.Pattern = patrn "设置模式。regEx.IgnoreCase = True "设置是否区分字符大小写。regEx.Global = True "设置全局可用性。Set Matches = regEx.Execute(strng) "执行搜索。For Each Match in Matches "遍历匹配集合。RetStr = RetStr & "Match found at position "RetStr = RetStr & Match.FirstIndex & ". Match Value is ""RetStr = RetStr & Match.Value & ""." & vbCRLFNextRegExpTest = RetStrEnd FunctionMsgBox(RegExpTest("is.", "IS1 is2 IS3 is4"))
