Hello Vishnulalr,

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

C#

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();
    }
}

You can access the attributes directly:

C#

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);
}

But I suggest you declare a class, and use deserialization instead. Look here: http://undefinedvalue.com/2011/11/22/deserializing-objects-xml-c[^]

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.
