我如何在c#中解析它，例如，我如何在答案中获得元素的值与ID="START"->响应->响应与ID 3->键

使用c#读取xml

您应该阅读有关LINQ to XML的内容。在这里问任何问题之前，你绝对应该做到这一点!

使用XDocument.Load方法可以轻松地将XML加载到XDocument对象中:

var dox = XDocument.Load("Input.txt");

然后使用标准的LINQ to XML语法进行查询:

var response = (from a in dox.Root.Elements("answerswer")
                where (string)a.Attribute("ID") == "ANSWER_1"
                from r in a.Element("responses").Elements("response")
                where (int)r.Attribute("id") == 1
                select r).FirstOrDefault();

或XPath选择器:

var response = dox.XPathSelectElement("answerswers/answer[@ID='ANSWER_1']/responses/response[@id='1']");
