xml - XML 查询 (Xpath)

问题描述

我正在尝试获取有关特定演员的所有详细信息，并找到这个特定的演员，我有接收 XMLDoc 和 2 个字符串参数的函数：名字和姓氏，在我下面的代码中，我总是得到 0 个 NodesElements。有人可以告诉我我做错了什么吗？

 public XmlNodeList Query3(XmlDocument xmlDoc, String actorFirstName, String actorLastName)// returns all the awards of all TV-shows of an actor
        {
string s = "Netflix/movies/movie/actors/actor[first-name="+actorFirstName+"last-name="+actorLastName+"]";
            XmlNodeList xmlNodeList = xmlDoc.SelectNodes(s);
            foreach (XmlNode x1 in xmlNodeList)
            {
                Console.WriteLine(x1.InnerText);
            }
            return xmlNodeList;
}

解决方案

改变

[first-name="+actorFirstName+"last-name="+actorLastName+"]";

至

[first-name="+actorFirstName+" and last-name="+actorLastName+"]";
                              ^^^^^
