Question

我想从此页面中提取标题和其他信息，请帮忙。

我这样做是为了从这个网址获取mp3的下载链接：http://mp3monkey.net/mp3/Eminem.html

private HtmlNodeCollection GetSongNodesMp3Monkey(string pageUri)
{
    HtmlDocument document = web.Load(pageUri);
    HtmlNode documentNode = document.DocumentNode;
    return documentNode.SelectNodes("//a[@href]");
}

void Mp3Monkey(HtmlNodeCollection songs)
{
    foreach (HtmlNode s in songs)
    {
        HtmlAttribute aa = s.Attributes["href"];
        if (aa.Value.EndsWith("?dl=1"))
        {
            list.Items.Add(aa.Value.Replace("?dl=1",""));
        }
     }
}

但我想提取其他信息，如标题和持续时间以及艺术家，请帮我这样做。

示例Html：

            <img src="Eminem%20Mp3%20Download_files/play.png" title="Play">
        </span>
        <span class="ui-icon ui-icon-pause" id="ui-icon-pause" style="display:none">
            <img src="Eminem%20Mp3%20Download_files/pause.png" title="Pause">

    </div>
</td>
<td style="width:34px">
    <div class="dd" style="width:34px; padding-top: 2px; padding-bottom: 4px;">
        <noindex>
            <div id="addmp3_18ffbe2d9efe71aed310552f4f79ad55">

                <img src="Eminem%20Mp3%20Download_files/addok.png" title="Added" id="is_add2" style="display:none">
                <span style="display:none" id="aid">92960819</span>

                <span style="display:none" id="title">Love the Way You Lie (feat. Rihanna)</span>
                <span style="display:none" id="time">263</span>

    </div>

Answer 1

var xpath = "//div[@class='dd']/noindex/div";
var songs = from song in hdoc.DocumentNode.SelectNodes(xpath)
            select new {
                Author = song.SelectSingleNode("span[@id='autor']").InnerText,
                Title = song.SelectSingleNode("span[@id='title']").InnerText,
                Time = song.SelectSingleNode("span[@id='time']").InnerText
            };

输出：

[
  {
    Author: "Eminem",
    Title: "Love the Way You Lie (feat. Rihanna)",
    Time: "263"
  },
  {
    Author: "Eminem ft. Akon ",
    Title: "Smack That ",
    Time: "217"
  },
  {
    Author: "Dr. Dre Feat. Eminem &amp; Skylar Grey",
    Title: "I Need A Doctor ( 2011 )",
    Time: "283"
  },
  ...
]
