HTMLAgilityPack获取带有id属性的td标签的innerText

问题描述：

我正在尝试使用HTMLAgilityPack选择具有id属性的td的内部文本.

I am trying to select the inner text of a td with an id attribute with the HTMLAgilityPack.

HTML代码:

<td id="header1">    5    </td>
<td id="header2">    8:39pm    </td>
<td id="header3">    8:58pm    </td>
...

代码:

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();

doc.LoadHtml(data);

var nodes = doc.DocumentNode.SelectNodes("//td[@id='header1']");

if (nodes != null)
{
    foreach (HtmlAgilityPack.HtmlNode node in nodes)
    {
        MessageBox.Show(node.InnerText);
    }
}

我一直得到空节点，因为我没有正确选择td标签，但无法弄清楚我做错了什么...

I keep getting null nodes because I am not selecting the td tag correctly but cannot figure out what I have done wrong...

我在header1和header2上弄错了，但是有5个不同的td标签，它们的标题为1到5.

I made a mistake with header1 and header2, but there are 5 different td tags with headers 1 to 5.

答

您正在尝试选择header1，但ID为header2.

You are trying to select header1 but the id is header2.

您也可以直接使用GetElementById:

var td = doc.GetElementbyId("header2");
