根据输入读取xml数据 [英] to read xml data based on input

问题描述

我有一个下拉列表，需要从1-4中选择任何一个.
如果我选择1，我想读取第一个id(即，父id ="1")内部节点并将其存储到某个变量.
如果我选择2，则应存储第二个ID(即，父ID ="2")详细信息.
因此应在为"id"指定的值上读取xml文件.

xml文件看起来像这样

I have a dropdown list where i need to select any one from 1-4.
if i select 1 i want to read the first id(i.e parent id="1") inner nodes and store it to some variable.
If i select 2 the second id(i.e parent id="2") details should get stored.
so the xml file should be read on the value given for "id".

the xml file looks something like this

<root>
  <greatgrandparent>
    <grandparent>
      <parent id="1">
        <child somevalue="3"></child>
      </parent>
      <parent id="2">
        <child somevalue="4"></child>
        <child somevalue="5"></child>
      </parent>
    </grandparent>
  </greatgrandparent>
</root>

有人可以帮我吗?
预先感谢.

can anyone help me out???
Thanks in advance.

推荐答案

以下是示例代码:

Here is the sample code:

XmlNodeList nodes = XMLRead.SelectNodes(@"grandparent"); 
foreach (XmlNode node in nodes)            
{                 
     string event1 = node.InnerText;
     listBoxOuter.Items.Add(event1);

     foreach (XmlNode n in node)                 
     {                     
             string event2 = n.FirstChild.InnerText; 
             listBoxOuter.Items.Add(event2);

             XmlNodeList nodes2 = node.ChildNodes;

             for (int i = 0, ii = nodes2.Count; i < ii; i++)
             {
                    XmlNode n = nodes2.Item(i);
                    string event2 = n.InnerText;
                    listBoxInner.Items.Add(event2);
             }

      }                                                              
 }
