.Net XML 增删改查

一般我们在游戏或者软件制作中，一般使用JSON和XML会比较多，Json的话比较轻量，Xml的话结构版式会复杂点，下面是xml读和写！！！

using UnityEngine;

using System.Collections;

using System;

using System.IO;

using System.Xml;

using System.Collections.Generic;

public class XmlCreate:MonoBehaviour

{

public void CreateXml()

{

//第一种写法直接插入

//注意xml都是字符类型的

string uarl = Application.streamingAssetsPath + "/ly.xml";

XmlDocument pDocument = new XmlDocument();

XmlDeclaration pDeclaration = pDocument.CreateXmlDeclaration("1.0", "UTF-8", null);//定制我们的版式说明是必须的

pDocument.AppendChild(pDeclaration);//版式说明建立

//根节点建立

XmlElement pRoot = pDocument.CreateElement("Books");

pDocument.AppendChild(pRoot);//将根节点插进去

XmlElement pBook = pDocument.CreateElement("book");

pRoot.AppendChild(pBook);//书的根节点

//XmlAttribute pBookAttribute = pDocument.CreateAttribute("id");//创建一个属性

//pBookAttribute.Value = System.Convert.ToString(01);

//pBook.Attributes.Append(pBookAttribute);//将属性插到指定节点中

//XmlElement pBookName = pDocument.CreateElement("name");

//pBookName.InnerText = "金瓶梅";

//pRoot.AppendChild(pBook);

//XmlElement pBookPice = pDocument.CreateElement("pice");

//pBookPice.InnerText = System.Convert.ToString(0.5f);

//pBook.AppendChild(pBookPice);

//XmlElement pBookMemo = pDocument.CreateElement("Memo");

//pBookMemo.InnerText = "听说这是一本插画很美的书适用于18+ 购买时请注意 *_*";

//pBook.AppendChild(pBookMemo);

//第二种写法用字典和元素构造

Dictionary<string, string> pContext = new Dictionary<string, string>();

pContext.Add("name", "金瓶梅");

pContext.Add("pice", System.Convert.ToString(0.5f));

pContext.Add("Memo", "听说这是一本插画很美的书适用于18+ 购买时请注意 *_*");

pRoot.AppendChild(pBook);

pContext.Clear();

pContext.Add("name", "优衣库");

pContext.Add("pice", System.Convert.ToString(0.8f));

pContext.Add("Memo", "听说这是一间秀色可餐的衣服间参观者18+ 心脏不好时请注意 *_*");

AppendChildNode(pDocument, pBook, ref pContext);

pBook = pDocument.CreateElement("book");

pRoot.AppendChild(pBook);

pContext.Clear();

pContext.Add("name", "西游记");

pContext.Add("pice", System.Convert.ToString(0.3f));

pContext.Add("Memo", "听说这是一本根据历史事实改编的古典小说观看者18+ 模仿者时请注意 *_*");

AppendChildNode(pDocument, pBook, ref pContext);

pDocument.Save(uarl);

}

//Xml元素构造 -写

public bool AppendChildNode(XmlDocument pDcument,XmlNode nParent,ref Dictionary<string,string>pKeyValue)

pNode.InnerText = pKeyValue[keys[i]];

nParent.AppendChild(pNode);

}

isRet = true;

}

while (false);

return isRet;

}

//读取XML -读

public void ReadXml()

{
