C#HtmlAgilityPack超文本标记语言解析问题

Question

我有这个

<div class="postrow firs">
        <h2 class="title icon">
            This is the title
        </h2>
        <div class="content">
            <div id="post_message_1668079">
                <blockquote class="postcontent restore ">
                <div>Category</div>
                                         <div>Authour: Kim</div>
                    line 1<br /> line2
                </blockquote>
            </div>
        </div>
    </div>      <div class="postrow">
        <h2 class="title icon">
            This is the title
        </h2>
        <div class="content">
            <div id="post_message_1668079">
                <blockquote class="postcontent restore ">
                <div>Category</div>
                    line 1<br /> line2
                </blockquote>
            </div>
        </div>
    </div>

我想从每个具有类“postrow”的div中提取以下内容，并且可能还有其他类，比如＜code＞

< li >带有类标题的标记内的内容 < li >来自“blockquote”标记的HTML。但不包括该标签内的任何div。

我尝试的代码：

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
            doc.LoadHtml("http://localhost/vanilla/");
            List<string> facts = new List<string>();
            foreach (HtmlNode li in doc.DocumentNode.SelectNodes("//div[@class='postrow']"))
            {
                facts.Add(li.InnerHtml);
                foreach (String s in facts)
                {
                    textBox1.Text += s + "/n";
                }
            }

Answer 1

您的代码有问题，必须将html作为字符串而不是路径

doc.LoadHtml("http://localhost/vanilla/");

代替

var request = (HttpWebRequest)WebRequest.Create("http://localhost/vanilla/");
String response = request.GetResponse();

doc.loadHtml(response);

现在迭代解析的html
