【问题描述】：

大家好，我尝试使用我拥有的属性值过滤 xml 文件并获取该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 的片段：

我想获取其他属性值...

【问题讨论】：

你的 C# 脚本有什么奇怪的打印方式？你也给了无效的xml，LICENSE_PATH和LM-X没有结束标签
这是一个片段，xml 更大...xD
xml 有 1500 行带有 FEATURE
所以您认为最好呈现不完整、无效、未格式化的 xml？

标签： c# xml linq linq-to-xml

【解决方案1】：

您可以使用Parent 属性。我已经修改了您的 xml 以使其有效。下一个代码打印你的 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);
}

打印：

ALTAIR

2014-03-31
2000
147000
