在VBScript普通防爆pressions？ [英] Regular Expressions in VbScript?

问题描述

VBScript中是否有正则表达式本机实现？我需要在一个旧的ASP应用程序验证电子邮件地址。

Does VbScript have a native implementation for Regex? I need to validate e-mail addresses on an old ASP application.

任何指针将是巨大的。

这例子是AlexCuse从<一个href=\"http://wiki.lessthandot.com/index.php/Using_Regular_Ex$p$pssions_For_Pattern_Matching_in_Access\"相对=nofollow> LessThanDot

This example is by AlexCuse from LessThanDot

Function ValidEmail(ByVal emailAddress) 

'this function will use regular expressions to check an '
'email address for validity '

'instantiate regex object container, output boolean '
Dim objRegEx, retVal 

'using late binding, vbscript reference is not required '
Set objRegEx = CreateObject("VBScript.RegExp") 

'.pattern -looks for a valid email address '
With objRegEx 
      .Pattern = "^\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b$" 
      .IgnoreCase = True 
End With 

retVal = objRegEx.Test(emailAddress) 

'get rid of RegEx object '
Set objRegEx = Nothing 

ValidEmail = retVal 

End Function
