asp中实现清除html的函数

这个函数是必需要的，很多黑客来捣乱，黑掉数据库，会注入大量的病毒js，在存储和展示文本数据的时候，使用此函数过滤一下，可避免不少麻烦

clearhtml代码

'清除HTML代码function clearhtml(content)  content=replacehtml("&#[^>]*;","",content)  content=replacehtml("</?marquee[^>]*>","",content)  content=replacehtml("</?object[^>]*>","",content)  content=replacehtml("</?param[^>]*>","",content)  content=replacehtml("</?embed[^>]*>","",content)  content=replacehtml("</?table[^>]*>","",content)  content=replacehtml(" ","",content)  content=replacehtml("</?tr[^>]*>","",content)  content=replacehtml("</?th[^>]*>","",content)  content=replacehtml("</?p[^>]*>","",content)  content=replacehtml("</?a[^>]*>","",content)  content=replacehtml("</?img[^>]*>","",content)  content=replacehtml("</?tbody[^>]*>","",content)  content=replacehtml("</?li[^>]*>","",content)  content=replacehtml("</?span[^>]*>","",content)  content=replacehtml("</?div[^>]*>","",content)  content=replacehtml("</?th[^>]*>","",content)  content=replacehtml("</?td[^>]*>","",content)  content=replacehtml("</?script[^>]*>","",content)  content=replacehtml("(javascript|jscript|vbscript|vbs):","",content)  content=replacehtml("on(mouse|exit|error|click|key)","",content)  content=replacehtml("<//?xml[^>]*>","",content)  content=replacehtml("<//?[a-z]+:[^>]*>","",content)  content=replacehtml("</?font[^>]*>","",content)  content=replacehtml("</?h[^>]*>","",content)  content=replacehtml("</?u[^>]*>","",content)  content=replacehtml("</?i[^>]*>","",content)  content=replacehtml("</?center[^>]*>","",content)  content=replacehtml("</?center[^>]*>","",content)  content=replacehtml("</?nobr[^>]*>","",content)  content=replacehtml("</?clk[^>]*>","",content)  content=replacehtml("</?muti[^>]*>","",content)  content=replacehtml("</?/option[^>]*>","",content)  content=replacehtml("</?o[^>]*>","",content)  content=replacehtml("</?strong[^>]*>","",content)  clearhtml=contentend function

replacehtml代码

function replacehtml(patrn,strng,content)    if isnull(content) then    content=""  end if  set regex=new regexp  regex.pattern=patrn  regex.ignorecase=true  regex.global=true  replacehtml=regex.replace(content,strng)end function

使用方法：

复制代码 代码如下:
<%=clearhtml("<div id="CodeTip"><h2>分享代码提示(2)</h2><ul><li style="font-weight: bold; color: rgb(170, 0, 0);">添加完代码必须点击“完成并查看”生效</li><li>准确的编程语言，可正确对代码语法着色</li><li>输入简单几个字的代码片段说明</li><li>上传源码文件时无需再输入说明</li><li>非程序相关文件将直接删除，严重封帐号</li><li>图片仅用来上传截图之类的文件，勿作他途</li></ul></div>")%>
