asp去除html的函数代码分析附实例说明

下面这段代码，不会替换ld<sad中间的<，所以内容仍然是正常的

<％
function nohtml(str)
dim re
Set re=new RegExp
re.IgnoreCase =true
re.Global=True
re.Pattern="(\<.[^\<]*\>)"
str=re.replace(str," ")
re.Pattern="(\<\/[^\<]*\>)"
str=re.replace(str," ")
str=replace(str," ","")
str=replace(str," ","")
nohtml=str
set re=nothing
end function
str="<title>sadjksjdlasp之家欢迎你sajdljsald<sadsadsad<br>" '这里是测试
response.write nohtml(str)
％>

结果为：

sadjksjdlasp之家欢迎你sajdljsald<sadsadsad

不过下面的代码是不问的，直接看到<就忘后面无限制的匹配

<％
Function dropHtml(Byval strHTML)
Dim objRegExp, Match, Matches
Set objRegExp = New Regexp
objRegExp.IgnoreCase = True
objRegExp.Global = True
'取闭合的<>
objRegExp.Pattern = "<.+?>"
'进行匹配
Set Matches = objRegExp.Execute(strHTML)
' 遍历匹配集合，并替换掉匹配的项目
For Each Match in Matches
strHtml=Replace(strHTML,Match.Value,"")
Next
dropHtml=strHTML
Set objRegExp = Nothing
End Function
str="<title>sadjksjdlasp之家欢迎你sajdljsald<sadsadsad<br>" '这里是测试
response.write dropHtml(str)
％>

结果为：

sadjksjdlasp之家欢迎你sajdljsald
