方法一 : 禁用HTML

最简单的方法是直接禁用html标签而不用移除它们. 可以使用Replace()函数. 例如:

strText = Replace(strText, "<script", "<script", 1, -1, 1)

或者直接禁用所有的html:

strText = Replace(strText, "<", "<")

这样做虽然很安全,但显得不够友好.(用户提交的文本会变得难以阅读)

方法二: 使用"<"和">"

怎样使得html标签从文本中消失呢? 我们可以去掉"<"和">"中间的所有内容

在JavaScript中这很简单:

function RemoveHTML( strText )

{

var regEx = /<[^>]*>/g

return strText.replace(regEx, "")

}

现在回到VBScript, 对于Scripting引擎5.0或更高版本(可以通过调用ScriptEngineMajorVersion和ScriptEngineMinorVersion函数来检验版本),我们也可以使用RegExp物体:

Function RemoveHTML( strText )

Dim RegEx

Set RegEx = New RegExp

RegEx.Pattern = "<[^>]*>"

RegEx.Global = True

RemoveHTML = RegEx.Replace(strText, "")

End Function

若不用正则表达式,下面的函数可以达到同样的目的:

Function RemoveHTML( strText )

Dim nPos1

Dim nPos2

nPos1 = InStr(strText, "<")

Do While nPos1 >0

nPos2 = InStr(nPos1 + 1, strText, ">")

If nPos2 >0 Then

strText = Left(strText, nPos1 - 1) &Mid(strText, nPos2 + 1)

Else

Exit Do

End If

nPos1 = InStr(strText, "<")

Loop

RemoveHTML = strText

End Function

以上的方法虽然都可以去掉括号内的html标签,但是这些方法都存在以下问题:

首先,文本内的任何不表示html的尖括号会被去除.而且两个尖括号中间的文本也会被删掉.换句话说,在文本中插入任何"<"或">"都会出现不可预料的结果.

另外,这种方法不能控制删除哪些html标签.比如<b><i>这些无害的标签通常是允许的.

方法三:使用IE或其他工具

有很多缺点:

"It may be desirable to parse HTML files inside a Web server process in response to a browser page request. However, the WebBrowser control, DHTML Editing Control, MSHTML, and other Internet Explorer components may not function properly in an Active Server Pages (ASP) page or other application run in a Web server application." (http://support.microsoft.com/support/kb/articles/Q244/0/85.ASP?LN=EN-US&SD=gn&FR=0)

方法四:VBScript

以下的函数可以限制到具体的html标签

简介:

要控制被删除的标签列表,可以通过向TAGLIST常数中添加/删除标记来实现. 例如,要保留所有的<B>标签,则从TAGLIST中删除B. 当前的列表包含了MSDN中的所有html标签以及 LAYER 标签. 每个标签要用""括起来.

开始标签和结束标签都会被删除,例如"<A...>"和</A...>

若标签同时在 TAGLIST 和 BLOCKTAGLIST 常数中,则起始标签和结束标签之间的所有内容都会被删除

没有结束标记的标签不被视为html标签,其内容不会被删除

块标签若没有结尾标记,从此标签开始到文本结束的所有内容会被删除

若"<!--"后跟的字符不是空格,注释标签不会被删除

使用这个函数很简单:

strPlainText = RemoveHTML(strTextWithHTML)

函数内容如下:

Function RemoveHTML( strText )

Dim TAGLIST

TAGLIST = "!--!DOCTYPEAACRONYMADDRESSAPPLETAREABBASEBASEFONT" &_

"BGSOUNDBIGBLOCKQUOTEBODYBRBUTTONCAPTIONCENTERCITECODE" &_

"COLCOLGROUPCOMMENTDDDELDFNDIRDIVDLDTEMEMBEDFIELDSET" &_

Const BLOCKTAGLIST = "APPLETEMBEDFRAMESETHEADNOFRAMESNOSCRIPTOBJECTSCRIPTSTYLE"

Dim nPos1

Dim nPos2

Dim nPos3

Dim strResult

Dim strTagName

Dim bRemove

Dim bSearchForBlock

nPos1 = InStr(strText, "<")

Do While nPos1 >0

nPos2 = InStr(nPos1 + 1, strText, ">")

If nPos2 >0 Then

strTagName = Mid(strText, nPos1 + 1, nPos2 - nPos1 - 1)

strTagName = Replace(Replace(strTagName, vbCr, " "), vbLf, " ")

nPos3 = InStr(strTagName, " ")

If nPos3 >0 Then

strTagName = Left(strTagName, nPos3 - 1)

End If

If Left(strTagName, 1) = "/" Then

strTagName = Mid(strTagName, 2)

bSearchForBlock = False

Else

bSearchForBlock = True

End If

If InStr(1, TAGLIST, "" &strTagName &"", vbTextCompare) >0 Then

bRemove = True

If bSearchForBlock Then

If InStr(1, BLOCKTAGLIST, "" &strTagName &"", vbTextCompare) >0 Then

nPos2 = Len(strText)

nPos3 = InStr(nPos1 + 1, strText, "</" &strTagName, vbTextCompare)

If nPos3 >0 Then

nPos3 = InStr(nPos3 + 1, strText, ">")

End If

If nPos3 >0 Then

nPos2 = nPos3

End If

End If

End If

Else

bRemove = False

End If

If bRemove Then

strResult = strResult &Left(strText, nPos1 - 1)

strText = Mid(strText, nPos2 + 1)

Else

strResult = strResult &Left(strText, nPos1)

strText = Mid(strText, nPos1 + 1)

End If

Else

strResult = strResult &strText

strText = ""

End If

nPos1 = InStr(strText, "<")

Loop

strResult = strResult &strText

RemoveHTML = strResult

End Function

没有几种.

原理就是删掉正则匹配到的html标签

至于删除用repalce还是remove我觉得没那么重要了就..

html标签的正则,网上抄的不知道对不对:

"<(.[^>]*)>"
