用于在C＃中替换div的简单代码

Question

I have a problem. I learn to edit html document in a simple program in C#, but i have a question.

i have a line code in HTML like that:

<div role = "banner" class = "TopBanner">

I want to change this line code in this:

<div role = "banner" class = "TopBanner" style = "display:none;">

i try to use

        HtmlElementCollection ElemCol= default(HtmlElementCollection);
        ElemCol= webBrowser.Document.GetElementsByTagName("div");
        foreach (HtmlElement curElement in ElemCol)
        {
            if (curElement.OuterHtml.Contains("TopBanner"))
            {
                curElement.Style = "display:none";
            }
        }

but is not working. my code just set display to none and don't replace the div with new text. Any ideas to replace the div?

Try this code:

HtmlElementCollection ElemCol= default(HtmlElementCollection);
ElemCol= webBrowser.Document.GetElementsByTagName("div");
foreach (HtmlElement curElement in ElemCol)
{
    if (curElement.GetAttribute("class").Contains("TopBanner"))
    {
        curElement.SetAttribute("style", "display:none");
    }
}

Try using SetAttribute

       if (curElement.OuterHtml.Contains("TopBanner"))
       {
                curElement.SetAttribute("style", "display:none");= "";
       }

我想你想使用setAttribute

curElement.setAttribute("style", "display:none")

If it's something you do a lot in your program (HTML manipulation), you may want to look at a project like CsQuery . It may give you much better control over stuff like this. If it's only something done a few times, a full assembly may be overkill.
