突出显示WebBrowser控件中的行 [英] highlighting lines in a WebBrowser control

问题描述

我正在使用WebBrowser控件在程序中显示xml文件.

I am using a WebBrowser control to display a xml file in my program.

是否可以突出显示特定的行或元素?(我也可以更改字体.)

Is there a way that i could highlight a specific line or element?(I gess changing the font will be ok also.)

如果没有，是否存在可以显示xml文件和突出显示行的控件，或者我需要为此做一个特殊的自定义控件吗?

If not, is there a control that can display xml files and highlight line, or do I need to make a special custom control for it?

谢谢

void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
  IHTMLDocument2 doc2 = webBrowser1.Document.DomDocument as IHTMLDocument2;
  StringBuilder html = new StringBuilder(doc2.body.outerHTML);

  var words = new[] { "laureati", "passione" };
  foreach (String key in words)
  {
   String substitution = "<span style='background-color: rgb(255, 255, 0);'>" + key + "</span>";
   html.Replace(key, substitution);
  }

  doc2.body.innerHTML = html.ToString();
}
