如何在C＃中的特定XML父节点中获取子节点值？

问题描述

我有xml文件Folders.xml，

Hi,
I hace xml file Folders.xml,

<root>
<Folder name="Planning">
  <subfolder name="Meeting Minuts"/>
  <subfolder name="Weekly Report"/>
  <subfolder name="Monthaly Report"/>
  <subfolder name="Design Image"/>
</Folder>
<Folder name="Engineering">
  <subfolder name="Engineering1"/>
  <subfolder name="Engineering2"/>
  <subfolder name="Engineering3"/>
  <subfolder name="Engineering4"/>
</Folder>
<Folder name="Quality">
  <subfolder name="Quality1"/>
  <subfolder name="Quality2"/>
  <subfolder name="Quality3"/>
  <subfolder name="Quality4"/>
</Folder>
</root>

刨光，工程和质量是组合框元素。当用户选择组合框作为Planing时，我需要显示规划中的所有子文件夹，如果他将选择Quality，那么所有子文件夹都应该显示，



我怎么能得到特定父母的子元素，



我尝试过：



这是获取Parent元素的代码。

Planing, Engineering and quality are the combobox element. When user will select combobox as Planing the i need to dispaly all the subfolder in the planning, if he will select Quality then all the subfolder should display,

How can I get subelement of perticular parent,

What I have tried:

here is the code to get Parent element.

XDocument myxml = XDocument.Load(@"Xml\Folders.xml");
            string str = string.Empty;
            foreach (XElement level1Element in XElement.Load(@"Xml\Folders.xml").Elements("Folder"))
            {
                str=(level1Element.Attribute("name").Value);
                Folders.Add(str);
            }
            cmb1.ItemsSource = Folders;

推荐答案

string folder = "Quality";
var subfolders = myxml.Root.Elements("Folder")
		.Where(x=>x.Attribute("name").Value==folder)
		.SelectMany(x=>x.Elements("subfolder")
                                .Select(y=>y.Attribute("name").Value))
		.ToList();

结果：

Result:

Quality1
Quality2
Quality3
Quality4
