C#使用xpath對html數據分析

先引用HtmlAgilityPack.dll，沒有的話下載一下

直接上代碼

                        var doc = new HtmlDocument();
                        doc.LoadHtml(html);//html字符串
                        //獲取標簽里的值
                        var nodes = doc.DocumentNode.SelectSingleNode("//div[@class='list-container']").InnerText;
                        //獲取一個多個節點，進行遍歷
                        var nodes_gjjl = doc_gjjl.DocumentNode.SelectNodes("//div[@class='project-follow']");

                        foreach (var item in nodes_gjjl)
                        {
                            string gjjl_time = item.SelectSingleNode("./table/tbody/tr[1]/td[2]/span").InnerText;
                        }
