我需要提取“file_name”属性的值以及值为“M5”＆amp;的属性的innertext。 “M6”。基本上它是文件的名称以及它中存在的类和方法的数量。任何解析方法都适合我。我尝试了一些方法，我可以提取file_name但无法进一步获取指标ID ..请帮助

答案 0 :(得分：0)
除了调用Elemnt/s方法（检索元素的子元素）和Descendants方法（检索元素的所有后代）以沿着元素路径前进之外，当你知道确切的路径时，你可以通过XPath（通过在代码的头部添加using指令using System.Xml.XPath;）来检索特定的节点（元素/属性）。
答案 1 :(得分：0)
使用Linq2XML，您可以编写查询来获取值。
见下文。
var elements = XElement.Parse(xml);
var files = elements.Element("project").Element("checkpoints").Element("checkpoint").Element("files").Elements("file").ToList();
var file_name = files[0].Attribute("file_name");
var M5 = files[0].Element("metrics").Elements("metric").Where(x => x.Attribute("id").Value.Equals("M5")).First().Value;
var M6 = files[0].Element("metrics").Elements("metric").Where(x => x.Attribute("id").Value.Equals("M6")).First().Value;
从变量'xml'
中的字符串加载xml你会注意到我只是在查询“可枚举”中的第一项...当然你可以决定该怎么做。
