从 asp.net 代码隐藏操作 HTML

Question

I am able to get the HTML from the code-behind, like this one:

protected override void OnPreRenderComplete(EventArgs e)
{
    StringWriter sw = new StringWriter();
    base.Render(new HtmlTextWriter(sw));
    sbHtml = sw.GetStringBuilder();
    Response.Write(sbHtml + "<!-- processed by code-behind -->");
}

But I need to remove the HTML from the Page, any help?

Answer 1

If I understand well you wish to manipulate the sbHtml, and write it out.

sbHtml = sw.GetStringBuilder();

sbHtml.Replace('anything','to anything');

Response.Write(sbHtml);

(or is something else?)

Answer 2

Did you want a method like this to strip the HTML?

public static string StripHTML(string HTMLText)
{
    var reg = new Regex("<[^>]+>", RegexOptions.IgnoreCase);
    return reg.Replace(HTMLText, "").Replace("&nbsp;", "");
}

Answer 3

You can put an <asp:placeholder> on the page and set the contents to whatever you want. Add/remove/whatever.
