过滤不安全的HTML代码

[AjaxPro.AjaxMethod()]

public String UnSafeHTMLFilter(string html)

{

Regex regex1 = new Regex(@"

Regex regex2 = new Regex(@" href *= *[\s\s]*script *:", RegexOptions.IgnoreCase);

Regex regex3 = new Regex(@" on[\s\s]*=", RegexOptions.IgnoreCase);

Regex regex4 = new Regex(@"", RegexOptions.IgnoreCase);

Regex regex5 = new Regex(@"

", RegexOptions.IgnoreCase);

html = regex1.Replace(html, ""); //过滤标记

html = regex2.Replace(html, ""); //过滤href=javascript: () 属性

html = regex3.Replace(html, " _disibledevent="); //过滤其它控件的on...事件

html = regex4.Replace(html, ""); //过滤iframe
