XML读取子节点 [英] XML reading child nodes

问题描述

我有一个XML文档，我正在尝试获取名为 Unit

I have an XML document and I am trying to get the childnodes of an element called Unit

我的XML文档的布局如下:

My XML Doc is layed out like so:

<Unit>
    <id>3</id>
    <name>System Information</name>
    <description>null</description>
    ... other ...
</Unit>

这是我用来尝试阅读它们的代码.

This is the code I am using to try and read them.

public void Load()
{
    FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
    XmlDocument xmldoc = new XmlDocument();
    XmlNodeList xmlnode;

    xmldoc.Load(fs);
    xmlnode = xmldoc.GetElementsByTagName("Units");

    for (int i = 0; i < xmlnode.Count; i++)
    {
        string str = string.Format("ID: {0}\r\nName:{0}", xmlnode[i].ChildNodes.Item(0).InnerText, xmlnode[i].ChildNodes.Item(1).InnerText);
        MessageBox.Show(str);
    }
}

但是问题是，当我尝试获取它们时，它不会显示项目0或项目1，而是显示所有项目，而不是我选择的项目.

But the problem is, when I try and get them, instead of getting item 0 or item 1, it displays all the items and not the items i have selected.

推荐答案

正如我从您的xml和代码中看到的那样.您在行中有错误:

As I can see from your xml and code. You have error in line:

 xmlnode = xmldoc.GetElementsByTagName("Units");

将其更改为:

 xmlnode = xmldoc.GetElementsByTagName("Unit");
