调查结果<div>,使用C#
原标题:Finding <div> in html using C#

我已经在StackOverflow上看到了一些关于类似主题的结果,他们都推荐使用HTML Agility Pack。我也找到了一些例子,但是它们都不能工作。我的当前代码:

        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml("http://stackoverflow.com/");
        List<string> facts = new List<string>();
        foreach (HtmlNode li in doc.DocumentNode.SelectNodes("//div"))
        {
            facts.Add(li.InnerText);
            foreach (String s in facts)
            {
                textBox1.Text += s + "/n";
            }
        }

我在doc.DocumentNode.SelectNodes("//div")处遇到了错误空引用未处理

另外,作为另一个问题,我如何找到一个特定名称的div?

最佳回答

关于问题1:在我看来它是正确的。你确定文档已经正确加载了吗?

r.e. q2: 使用XPath:div[@id=idToFind]
