SelectNodes错误

Question

我想把这个写在html里

<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，我在这里也使用HtmlAGilityPack，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();

以下是错误：

'HtmlAgilityPack.HtmlNode‘不包含'SelectNodes’的定义，也找不到接受'HtmlAgilityPack.HtmlNode‘类型的第一个参数的扩展方法'SelectNodes’(您缺少使用指令还是程序集引用？)

如果没有看到代码的其余部分，就很难进行测试。但是，尝试用DocumentNode.SelectNodes替换DocumentElement.SelectNodes。

来自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");
