Unity上使用Linq To XML

using UnityEngine;

using System.Collections;

using System.Linq;

using System.Xml.Linq;

using System;

public class XML {

//static string xmlpath = Application.persistentDataPath + @"\myXML";//平台相关的路径（移动端）

static string xmlpath=Application.dataPath+@"\mydfdfXML";//电脑上的路径，移动端没有这个访问权限

/// <summary>

/// 初始化一个XML文件

/// </summary>

public static void CreateXMLDocument()

{

XElement root = new XElement("XMLContent",

new XElement("Herb1",new XAttribute("MyVaule","")),

new XElement("Herb2",new XAttribute("MyVaule","")),

new XElement("Herb3",new XAttribute("MyVaule","")),

new XElement("Pill1",new XAttribute("MyVaule","")),

new XElement("Pill2",new XAttribute("MyVaule","")),

new XElement("Pill3",new XAttribute("MyVaule","")),

new XElement("Level",new XAttribute("MyVaule","")),

new XElement("Root","root")

);

root.Save(xmlpath);

}

public static XElement LoadXMLFromFile()

{

XElement root = XElement.Load(xmlpath);

return root;

}

public static void SetElementValue(string name, string value)

{

XElement root = LoadXMLFromFile();

root.Element(name).SetAttributeValue("MyVaule", value);

root.Save(xmlpath);

}

/// <summary>

/// 在根节点元素之前添加新的元素

/// </summary>

/// <param name="name">元素名字</param>

/// <param name="value">元素的值</param>

public static void AddElement(string name, string value)

{

XElement root = LoadXMLFromFile();

root.Element("Root").AddBeforeSelf(new XElement(name, new XAttribute("MyValue",value)));

root.Save(xmlpath);

}

/// <summary>

/// 删除指定的元素

/// </summary>

}

}

1.写XML文件

XElement xperson = new XElement("person");//根节点
xperson.SetAttributeValue("age", 30);//设置属性
XElement xperson1 = new XElement("person1");
xperson1.Value = "tom";//设置 innerText值
xperson1.SetAttributeValue("sex", "男");
XElement xperson2 = new XElement("person2");
xperson.Add(xperson1);//加入到根结点
xperson.Add(xperson2);
string xml = xperson.ToString();
Console.WriteLine(xml);
using (Stream stream = File.OpenWrite(@"D:\1.xml"))
{
byte[] bytes = new byte[1024];
bytes = Encoding.UTF8.GetBytes(xml);
stream.Write(bytes, 0, bytes.Length);//写入文件
}

2.读取XML文件

----------如何读取xml文件的内容----------------

using(Stream stream=File.OpenRead(@"D:\1.xml"))
            {
               using(StreamReader reader= new StreamReader(stream))
               {
                   //从Reflector从可以看到TextReader的子类是StreamReader所以，可以直接用StreamReader来读取XML文档，传给XDocument.Load方法
                  XDocument xml=XDocument.Load(reader);//load里面
                  Console.WriteLine( xml.Root.ToString());//xml文档
                  Console.WriteLine(xml.Root.Nodes().ElementAt(0).ToString());//ElementAt()第几个子节点
                  Console.WriteLine(xml.Root.Attribute("age").Value);//返回根节点的属性的值
                  XNode nodes=xml.Root.Nodes().ElementAt(0);
                  XElement e=nodes as XElement;
                  Console.WriteLine(e.Attribute("sex").Value);//读取第一个子节点的属性
                }

            }

3.读取App.Config

using (Stream stream = File.OpenRead(@"D:\net实例教程\练习net\XML练习\XML练习\App.config"))
            {
                using (StreamReader reader = new StreamReader(stream))
                {
                    XDocument xml = XDocument.Load(reader);
                    XNode n1 = xml.Root.Nodes().ElementAt(0);//这就是<configuration> ------下面----<connectionStrings>
                    XElement e1 = n1 as XElement;
                    XNode n1_1 = e1.Nodes().ElementAt(0);//connectionStrings下面的<add .....>第一个
                    XNode n1_2 = e1.Nodes().ElementAt(1);//connectionStrings下面的<add .....>第一个
                    XElement e1_1 = n1_1 as XElement;
                    XElement e1_2 = n1_2 as XElement;
                    //Console.WriteLine("Name={0},Connection={1}", e1.Attribute("name").Value, e1.Attribute("connectionString").Value);
                    Console.WriteLine("第一个连接字符串的name={0},Connection={1}", e1_1.Attribute("name"), e1_1.Attribute("connectionString"));

Console.WriteLine("第一个连接字符串的name={0},Connection={1}", e1_2.Attribute("name"), e1_2.Attribute("connectionString"));

}
}

using (Stream stream = File.OpenRead(@"D:\net实例教程\练习net\XML练习\XML练习\App.config"))
{
using (StreamReader reader = new StreamReader(stream))
{
XDocument xml=XDocument.Load(reader);
IEnumerable<XElement> XConnstr = xml.Root.Elements("connectionStrings");
Console.WriteLine(XConnstr.Count().ToString());
if (XConnstr.Count() == 1)
{
XElement Connstr = XConnstr.ElementAt(0);
foreach(XElement conn in Connstr.Elements("add"))
{
string name = conn.Attribute("name").Value;
string Connection = conn.Attribute("connectionString").Value;
Console.WriteLine("Name={0},Age={1}", name, Connection);
}
}
}
}
