c# - 在反序列化期间获取任意深度的 XMLElement
问题描述
我是 c# 和 XML 反序列化的新手，请原谅我的任何错误单词/遗漏任何信息。
我正在反序列化带有根元素的 Nunit3 测试结果 XML 作为测试运行，子元素是测试套件，然后是测试用例。
测试用例根据执行的测试用例的数量以及我感兴趣的元素重复多次。
Nunit XML 的 C# 类如下所示。
[XmlRoot(ElementName = "test-run")]
public class Testrun
{
[XmlElement(ElementName = "command-line")]
public string Commandline { get; set; }
[XmlElement(ElementName = "test-suite")]
public Testsuite Testsuite { get; set; }
}
[XmlRoot(ElementName = "test-suite")]
public class Testsuite
{
[XmlElement(ElementName = "test-case")]
public Testcase Testcase { get; set; }
}
但有时嵌套的测试套件元素会出现在 Nunit XML 中，如下所示。
<test-suite type="TestSuite" id="0-1005" name="TopGearFramework" fullname="TopGearFramework" runstate="Runnable" testcasecount="2" result="Failed" site="Child" start-time="2019-02-21 04:17:28Z" end-time="2019-02-21 04:19:16Z" duration="108.354384" total="2" passed="1" failed="1" warnings="0" inconclusive="0" skipped="0" asserts="14">

请注意，在测试用例发生之前，测试套件会重复 5 次。在反序列化过程中，我将 null 变为测试用例对象。
如何处理测试套件元素的动态嵌套或重复以获得测试用例？
提前致谢。

解决方案
如果您想<test-case>在 XML 中获取任何深度的所有节点，那么XDocument.Descendants("test-case")将为您执行此操作。
通过使用 LINQ，您可以从result每个<test-case>节点和节点（如果存在于节点内）检索属性。message<failure><test-case>
然后下面的代码为您提供了带有结果的失败消息列表。
class Program
{
public static void Main(string[] args)
{
XDocument doc = XDocument.Load(@"Path to your xml file");
var result = (from t in doc.Descendants("test-case")
from f in t.Descendants("failure")
select new
{
Result = t.Attribute("result").Value,
Failure_Message = f.Element("message") != null ? f.Element("message").Value : ""
}).ToList();
//---------------Print the result------------------
foreach (var item in result)
{
Console.WriteLine("Result: " + item.Result);
Console.WriteLine("Message: " + item.Failure_Message);
}
Console.ReadLine();
}
