我如何从xml获取来自同一节点的其他属性值的属性值？

大家好我尝试使用我拥有的属性值过滤xml文件，并获取此节点的所有其他属性值。

这是我的c＃代码：

string search_string = "GlobalZoneEU";

            XElement xelement = XElement.Load(path_of_hw);
            var node = from nm in xelement.Elements("LICENSE_PATH")
                       where (string)nm.Element("FEATURE").Attribute("NAME") == search_string
                       select nm;

            Console.WriteLine("Show");

            foreach (XElement xle in node)
            {
                Console.WriteLine(xle.Attribute("NAME").Value);
                Console.WriteLine(xle.Attribute("VERSION").Value);
                Console.WriteLine(xle.Attribute("VENDOR").Value);
                Console.WriteLine(xle.Attribute("START").Value);
                Console.WriteLine(xle.Attribute("END").Value);
                Console.WriteLine(xle.Attribute("USED_LICENSES").Value);
                Console.WriteLine(xle.Attribute("TOTAL_LICENSES").Value);
            }

            Console.ReadLine();

这是我的测试xml的剪辑：

我想获得其他属性值...

您可以使用Parent属性。我修改了你的xml以使其有效。下一个代码打印foreach循环中的所有值

string search_string = "GlobalZoneEU";

var xDoc = XDocument.Load(path_of_hw);

var users = xDoc.Root
                .Elements("LICENSE_PATH")
                .Select(license => license.Element("FEATURE"))
                .Where(feature => (string)feature.Attribute("NAME") == search_string)
                .Select(feature => feature.Element("USER"));

foreach (var xle in users)
{
    Console.WriteLine(xle.Attribute("NAME").Value);
    Console.WriteLine(xle.Parent.Attribute("VERSION").Value);
    Console.WriteLine(xle.Parent.Attribute("VENDOR").Value);
    Console.WriteLine(xle.Parent.Attribute("START").Value);
    Console.WriteLine(xle.Parent.Attribute("END").Value);
    Console.WriteLine(xle.Attribute("USED_LICENSES").Value);
    Console.WriteLine(xle.Parent.Attribute("TOTAL_LICENSES").Value);
}
