C# 对于此示例,如何使用HtmlAlityPack从HTML中提取文本?,c#,linq,xpath,html-agility-pack,html-content-extraction,C#,Linq,Xpath,Html Agility Pack,Html Content Extraction,我想从HTML源代码中提取文本。我正在尝试使用c#和htmlagilitypack dll 资料来源是: <table> <tr> <td class="title"> <a onclick="func1">Here 2</a> </td> <td class="arrow"> <img src="src1" width="9" height="8" al

我想从HTML源代码中提取文本。我正在尝试使用c#和htmlagilitypack dll

资料来源是:

<table>
  <tr>
    <td class="title">
      <a onclick="func1">Here 2</a>
    </td>
    <td class="arrow">
      <img src="src1" width="9" height="8" alt="Down">
    </td>
    <td class="percent">
      <span>39%</span>
    </td>
    <td class="title">
      <a onclick="func2">Here 1</a>
    </td>
    <td class="arrow">
      <img src="func3" width="9" height="8" alt="Up">
    </td>
    <td class="percent">
      <span>263%</span>
    </td>
  </tr>
</table>

这里2
39%
这里1
263%
我怎样才能从表中得到这里1和这里2的文本

HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml("web page string");
var xyz = from x in htmlDoc.DocumentNode.DescendantNodes()
                     where x.Name == "td" && x.Attributes.Contains("class")
                     where x.Attributes["class"].Value == "title"
                     select x.InnerText;
不是很漂亮,但是应该可以用Xpath版本

 HtmlDocument doc = new HtmlDocument();
 doc.LoadHtml(t);

 //this simply works because InnerText is iterative for all child nodes
 HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//td[@class='title']");
//but to be more accurate you can use the next line instead
//HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//td[@class='title']/a");


 string result;
 foreach (HtmlNode item in nodes) 
       result += item.InnerText;
对于LINQ版本,只需更改var节点=。。符合:

 var Nodes = from x in htmlDoc.DocumentNode.DescendantNodes()
                  where x.Name == "td" && x.Attributes["class"].Value == "title"
                  select x.InnerText;

如何显示单元格文本?请使用innerText,也可以在xpath中使用text(),如“/td[@class='title']/a/text()”
