这是我要选择元标记的 XML
<meta charset="utf-8">
<title>Gmail: Email from Google</title>
<meta name="description" content="10+ GB of storage, less spam,
and mobile access. Gmail is email that's intuitive, efficient, and
useful. And maybe even fun.">
<link rel="icon" type="image/ico" href="//mail.google.com/favicon.ico">
我正在这样做
string texturl = textBox2.Text;
string Url = "http://" + texturl;
HtmlWeb web = new HtmlWeb();
HtmlAgilityPack.HtmlDocument doc = web.Load(Url);
var SpanNodes = doc.DocumentNode.SelectNodes("//meta");
if (SpanNodes != null)
{
foreach (HtmlNode SN in SpanNodes)
{
string text = SN.InnerText;
MessageBox.Show(text);
}
它实际上并没有从那里选择任何文本............我做错了什么请帮忙
