Question

我想在html

中得到这个

<div id="lyrics-body-text">
<p class='verse'>It's been a long and winding journey<br/>
But I'm finally here tonight picking up the pieces<br/>
And walking back into the night into the sunset of your glory<br/>
When my heart and future lies there's nothing like that feeling<br/>
When I look into your eyes</p></div>

使用C#和XAML，我也使用HtmlAGilityPack 这是我的代码：

HttpClient wClient = new HttpClient();
responseData = await wClient.GetByteArrayAsync(URL);
UTF8Encoding utf8 = new UTF8Encoding();
String Lyrics = utf8.GetString(responseData, 0, responseData.Length);

StringBuilder pureText = new StringBuilder();
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(Lyrics);

try
{
     foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//div[@id='lyrics-body-text']")) // error
     {
           pureText.Append(node.InnerText);
     }
}
catch
{ }

return pureText.ToString();

这是错误：

'HtmlAgilityPack.HtmlNode'不包含。的定义 'SelectNodes'并且没有扩展方法'SelectNodes'接受第一个可以找到类型'HtmlAgilityPack.HtmlNode'的参数（是吗？缺少using指令或程序集引用？）

如果没有看到其余的代码，就很难进行测试。不过，请尝试将DocumentNode.SelectNodes替换为DocumentElement.SelectNodes。

从HtmlAgilityPack文档示例代码：

 HtmlDocument doc = new HtmlDocument();
 doc.Load("file.htm");
 foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"]))
 {
    HtmlAttribute att = link["href"];
    att.Value = FixLink(att);
 }
 doc.Save("file.htm");

选择节点错误
