C# html 敏捷包无法在循环中获取唯一内容

Question

我正在尝试抓取文章、标题和完整文章的 URL 网站。在我的循环中，我一直为每个运行获得相同的标题，但我的 URL 是独一无二的并且有效。我 missing/doing 哪里错了？是不是方法不对？

// List
var content = htmlDoc.DocumentNode.SelectNodes("/html/body/div/div/div/div/div/div/div/div/div/article").ToList();

foreach (var article in content)
{

    // Get news title
    string articleUrl = article.SelectSingleNode("a").Attributes["href"].Value;
                
    // Get url to full content
    string articleTitle = article.SelectSingleNode("//div[@class='dre-item__alt-title--md']/div").InnerText;


    Console.WriteLine("Title: {0}", articleTitle);
    Console.WriteLine("Url: {0}", articleUrl);
    Console.WriteLine("--------");

}

输出，

Answer 1

以 / 开头的 XPath 表达式从根开始，即使您在子节点上调用它也是如此。
以 .// 开始表达式以从该“文章”节点开始。
