Question

我想要提取的不是整个网页而只提取一个类的文字，我想要来自td class =＆＃34;结果中立的文本＆＃34;我不知道这段代码有什么问题：

<td class="result-neutral" xseid="xz1nBfht"><a href="/hockey/russia/khl/ska-st-petersburg-metallurg-magnitogorsk-xz1nBfht/">3 - 2 </a></td>

这是C＃代码：

HtmlAgilityPack.HtmlDocument doc = new HtmlDocument();
        HtmlWeb hw = new HtmlWeb();
        doc = hw.Load("htt
var scoreNodes = doc.DocumentNode.Descendants("td").Where(d =>d.Attributes.Contains("class")&&d.Attributes["class"].Value.Contains("result-neutral"));

        foreach (var item in scoreNodes)
        {
            result += item.OuterHtml + Environment.NewLine;
        }
        Info.Text = result;

    }

Answer 1

OuterHtml返回html with start＆amp;元素的结尾。不想要InnerHtml或InnerText？

修改这段代码对我有用：

const string html = @"<html><body><table><tr><td class='result-neutral' xseid='xz1nBfht'><a href='/hockey/russia/khl/ska-st-petersburg-metallurg-magnitogorsk-xz1nBfht/'>3 - 2</a></td></tr></table></body></html>"; var doc = new HtmlDocument(); doc.LoadHtml(html); var scoreNodes = doc.DocumentNode.Descendants("td").Where(d => d.Attributes.Contains("class") && d.Attributes["class"].Value.Contains("result-neutral")); string result = ""; foreach (var item in scoreNodes) { result += item.InnerText + Environment.NewLine; } result = result.TrimEnd(); // the result is "3-2"
