this is what i currently have

What I have tried:

var url = "https://sketchfab.com/3d-models/steyr-aug-a3-4cea993b9f0d47c6b1beed7877b17447";

using (HttpClient client = new HttpClient())
{
    using (HttpResponseMessage response = client.GetAsync(url).Result)
    {
        using (HttpContent content = response.Content)
        {
            string result = content.ReadAsStringAsync().Result;
            System.IO.File.WriteAllText(Application.StartupPath + "rip.html", result);
        }
    }
}


var path = Application.StartupPath + "rip.html";

var doc = new HtmlAgilityPack.HtmlDocument();
doc.Load(path);

var node = doc.DocumentNode.SelectSingleNode("\\div class");

推荐答案

Quote：

var node = doc.DocumentNode.SelectSingleNode("\\div class");

[]需要一个XPath表达式。字符串 \ diviv 不是XPath表达式。

[]

如果你想选择所有< div> 元素有一个 class 属性，使用：

The SelectSingleNode method[^] expects an XPath expression. The string \div class is not an XPath expression.

XPath Tutorial[^]

If you want to select all <div> elements which have a class attribute, use:

var node = doc.DocumentNode.SelectSingleNode("//div[@class]");
