请帮我读一下xml并将其存储在一个字符串中 [英] Please help me to read the xml and store it in a string

问题描述

我想读取x，y，角度，方向，文件的值

I want to read the values of x,y,angle,direction,file

<DESCIONTREE>
 
  <Motion X="296" Y="88" Angle="-90" Direction="up" file="2.jpg" />
  <Motion X="384" Y="94" Angle="90" Direction="down" file="2.jpg" />
  <Motion X="480" Y="94" Angle="90" Direction="down" file="2.jpg" />
  <Motion X="272" Y="106" Angle="90" Direction="down" file="2.jpg" />
 
</DESCIONTREE>

string contents = File.ReadAllText("test.xml");
 
          XmlDocument xml = new XmlDocument();
            xml.LoadXml(contents);  // suppose that str string contains "<Names>...</Names>"
 
            XmlNodeList xnList = xml.SelectNodes("/DESCIONTREE/Motion");
 
            foreach (XmlNode xn in xnList)
            {
               // Console.WriteLine(xn.InnerText);
 
                richTextBox1.AppendText(xn.OuterXml+ "\n");
            }

但我想存储每个变量

but i want to store each variable

String x,y,angle,direction,file ;

推荐答案

您可以直接访问这些属性：

You can access the attributes directly:

XmlDocument xml = new XmlDocument();
xml.LoadXml(@"
<DESCIONTREE>
  <Motion X='296' Y='88' Angle='-90' Direction='up' file='2.jpg' />
  <Motion X='384' Y='94' Angle='90' Direction='down' file='2.jpg' />
</DESCIONTREE>
");

XmlNodeList xnList = xml.SelectNodes("/DESCIONTREE/Motion");


foreach (XmlNode xn in xnList)
{
    Console.WriteLine("{0} {1} {2} {3} {4}", xn.Attributes["X"].Value, xn.Attributes["Y"].Value, xn.Attributes["Angle"].Value, xn.Attributes["Direction"].Value, xn.Attributes["file"].Value);
}

但我建议您声明一个类，然后使用反序列化。请看这里： http://undefinedvalue.com/2011/11/22/deserializing-objects-xml -c [ ^ ]

您好，



您已经阅读了以下属性：





foreach（xnList中的xmlNode xn）

{

string attributeValue = xn.Attributes [X ]。值; //得到X值。

}



希望这可以解决你的问题。



问候

Hi,

you have read the attributes which you can achieve by following:


foreach (XmlNode xn in xnList)
{
string attributeValue = xn.Attributes["X"].Value; // to get the X value.
}

Hope this can solve your problem.

Hello Vishnulalr，



以下代码片段演示如何从节点读取单个属性值。

Hello Vishnulalr,

Following code snippet demonstrate how you can read individual attribute values from node.

using System;
using System.Xml;

class XMLTest {
    public static void Main() {
        XmlDocument xdoc = new XmlDocument();
        xdoc.Load("G:\\text.xml");
        XmlNodeList xnLst = xdoc.SelectNodes("/DESCIONTREE/Motion");
        foreach (XmlNode node in xnLst) {
            Console.WriteLine(node.Attributes.GetNamedItem("X").Value);
            Console.WriteLine(node.Attributes.GetNamedItem("Y").Value);
            Console.WriteLine(node.Attributes.GetNamedItem("Angle").Value);
            Console.WriteLine(node.Attributes.GetNamedItem("Direction").Value);
            Console.WriteLine(node.Attributes.GetNamedItem("file").Value);
            Console.WriteLine("");
        }
        Console.ReadKey();
    }
}

问候，
