用正则表达式过滤html代码

代码例子如下：
<%
Option Explicit

Function stripHTML(strHTML)
'Strips the HTML tags from strHTML

 Dim objRegExp, strOutput
 Set objRegExp = New Regexp

 objRegExp.IgnoreCase = True
 objRegExp.Global = True
 objRegExp.Pattern = "<.+?>"

 'Replace all HTML tag matches with the empty string
 strOutput = objRegExp.Replace(strHTML, "")

 'Replace all with < and >
 strOutput = Replace(strOutput, "<", "<")
 strOutput = Replace(strOutput, ">", ">")

 stripHTML = strOutput 'Return the value of strOutput

 Set objRegExp = Nothing
End Function
%>

<% if Len(Request("txtHTML")) > 0 then %>
 

 View of string with no HTML stripping:

 

 <%=StripHTML(Request("txtHTML"))%>
