using System.IO;
using System.Xml;

public class xml : MonoBehaviour {

	XmlDocument xmlDoc = new XmlDocument ();

	void Start ()
	{

		XmlDocument xmlDoc = new XmlDocument ();
		xmlDoc.Load ("Assets/1.xml");
		XmlNode root = xmlDoc.SelectSingleNode ("users");
		XmlNodeList nodeList = root.ChildNodes;

		foreach (XmlNode xn in nodeList)
		{
			XmlElement xe = (XmlElement)xn;
			XmlNodeList subList = xe.ChildNodes;
			foreach (XmlNode xmlNode in subList)
			{
				if ("name".Equals (xmlNode.Name))
				{
					Debug.Log (xmlNode.InnerText);
				}
				else if ("email".Equals (xmlNode.Name))
				{
					Debug.Log (xmlNode.InnerText);
				}
			}
		}
