Question

我有一个html并使用带有c＃的htmlagilitypack。我需要获取特定的子节点值。我需要得到孩子的文字＆＃34; strong / em＆＃34;在HTML中。我怎么才能得到它？

<div id="top3">
       <li> February  1, 2016&#58; 
         <a target="_blank" href="test1.html"> 
            <strong> 
               <em>test1</em></strong>
          </a>

         <br><strong>desc1</strong></li>

<li> February  2, 2016&#58; 
         <a target="_blank" href="test2.html"> 
            <strong> 
               <em>test2</em></strong>
          </a>

         <br><strong>desc2</strong></li>

        </div>

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//div[@id='top3']//li"))
{                     
     sb.Append("<p'>" + node.SelectSingleNode("a[1]/preceding-sibling::text()[1]").InnerText + "</p>");
     linkNode = node.SelectSingleNode("a[1]");
     sb.Append("<p class='event'><a href='" + linkNode.Attributes["href"].Value + "'>" +  

        //**********Need to have text from  /strong/em/  here *********

     + "</a></p>");
}

通过使用相对于所选<!doctype html> <html> <head> <meta charset="utf-8"> <title>Untitled Document</title> </head> <body> <div> <input type="text" id="fname" placeholder ="Full Name" name="fullname"> <input type="text" id="job" placeholder ="Job" name="job"> <input type="text" id="country" placeholder ="Country" name="country"> <input type="text" id="city" placeholder ="City" name="city"> <input type="submit" value="Submit"> <p id="p1"></p> </div> <script> document.querySelector('input[type="submit"]').onclick = function() { function Person(fullname, job, country, city) { this.fullname = fullname; this.job = job; this.country = country; this.city = city; } var fullname = document.getElementById("fname").value; var job = document.getElementById("job").value; var country = document.getElementById("country").value; var city = document.getElementById("city").value; var me = new Person(fullname, job, country, city); document.getElementById("p1").innerHTML = me.fullname + ". Congratulations an object has been made with your information stored in it, the following information is what you have given us. Your job is a " + me.job + "You live in" + me.city + "," + me.country + "."; }; </script> </body> </html>元素的简单XPath，您可以获得strong/em的值，如下所示：

<a>

您已经在发布的代码段中演示了使用稍微复杂的XPath表达式，所以我有点想知道为什么会出现这个问题......
