推荐答案

下面是一个解决方案，我用从富文本编辑器擦洗传入HTML ...它写在VB.NET，我没有足够的时间转换为C＃ ，但它是pretty简单：

Here's a solution I use to scrub incoming HTML from rich text editors... it's written in VB.NET and I don't have time to convert to C#, but it's pretty straightforward:

 Public Shared Function CleanHtml(ByVal html As String) As String
     '' Cleans all manner of evils from the rich text editors in IE, Firefox, Word, and Excel
     '' Only returns acceptable HTML, and converts line breaks to <br />
     '' Acceptable HTML includes HTML-encoded entities.
     html = html.Replace("&" & "nbsp;", " ").Trim() ' concat here due to SO formatting
     '' Does this have HTML tags?
     If html.IndexOf("<") >= 0 Then
         '' Make all tags lowercase
         html = RegEx.Replace(html, "<[^>]+>", AddressOf LowerTag)
         '' Filter out anything except allowed tags
         '' Problem: this strips attributes, including href from a
         '' http://stackoverflow.com/questions/307013/how-do-i-filter-all-html-tags-except-a-certain-whitelist
         Dim AcceptableTags      As String   = "i|b|u|sup|sub|ol|ul|li|br|h2|h3|h4|h5|span|div|p|a|img|blockquote"
         Dim WhiteListPattern    As String   = "</?(?(?=" & AcceptableTags & ")notag|[a-zA-Z0-9]+)(?:\s[a-zA-Z0-9\-]+=?(?:([""']?).*?\1?)?)*\s*/?>"
         html = Regex.Replace(html, WhiteListPattern, "", RegExOptions.Compiled)
         '' Make all BR/br tags look the same, and trim them of whitespace before/after
         html = RegEx.Replace(html, "\s*<br[^>]*>\s*", "<br />", RegExOptions.Compiled)
     End If
     '' No CRs
     html = html.Replace(controlChars.CR, "")
     '' Convert remaining LFs to line breaks
     html = html.Replace(controlChars.LF, "<br />")
     '' Trim BRs at the end of any string, and spaces on either side
     Return RegEx.Replace(html, "(<br />)+$", "", RegExOptions.Compiled).Trim()
 End Function

 Public Shared Function LowerTag(m As Match) As String
   Return m.ToString().ToLower()
 End Function

在你的情况，你要修改AcceptableTags批复HTML标签的列表 - 在code仍将去除所有无用的属性（和，不幸的是，有用的像HREF和SRC，希望那些对你并不重要）。

In your case, you'll want to modify the list of "approved" HTML tags in "AcceptableTags"--the code will still strip all the useless attributes (and, unfortunately, the useful ones like HREF and SRC, hopefully those aren't important to you).

当然，这需要与服务器通信。如果你不希望出现这种情况，你需要某种形式的清理按钮，添加到调用JavaScript与编辑器的当前文本混乱的工具栏。不幸的是，粘贴，是不是可以被困自动清理标记的事件，和清洗后，每的OnChange将使一个不可用编辑器（由于更改标记更改文本光标位置）。

Of course, this requires a trip to the server. If you don't want that, you'll need to add some sort of "clean up" button to the toolbar that calls JavaScript to mess with the editor's current text. Unfortunately, "pasting" is not an event that can be trapped to clean up the markup automatically, and cleaning after every OnChange would make for an unusable editor (since changing the markup changes the text cursor position).
