<product> asdasd </product>
<command>goto ANSWРІER_2</command>
</response>

<response id="3">

<product> dscdsc</product>
<command>goto ANSWER_3</command>

</response>

</responses>

</answer>

<answer ID="ANSWER_3">
<text>asdasd</text>
<password>1</password>
<id>3</id>
<responses>

<response id="1">
<key>!1</key>
<product> asdasd </product>
<command>goto ANSWER_0</command>
</response>

<response id="2">
<key>!2</key>
<product>  </product>
<command>goto ANSWER_2</command>
</response>

<response id="3">
<key>!3</key>
<product> Testqdawd 3 </product>
<command>goto ANSWER_3</command>

</response>

</responses>

</answer>

我如何在 C# 中解析它，例如我如何在 ID="START"->responses->response with id 3->key 的回答中获得 elent 的价值

您应该阅读有关LINQ to XML的信息。在问任何问题之前，您绝对应该这样做！

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

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

然后使用标准 LINQ to XML 语法对其进行查询：

var response = (from a in dox.Root.Elements("answer")
                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("answers/answer[@ID='ANSWER_1']/responses/response[@id='1']");
