unity读写XML的相关操作

读写主要用到了

XmlDocument 类

XmlDocument.GetElementsByTagName 方法 (String)

返回一个 XmlNodeList，它包含与指定 Name 匹配的所有子代元素的列表。

using System;using System.Xml;using UnityEngine;class CarXMLConfigure{public const string Root="Root";public const string NetworkConfigure="NetworkConfigure";public const string IP="IP";public const string FileName="config.xml";public const string StreamingAssets="/StreamingAssets/";    public const string NM = "nm";    }class XMLManagement{private XmlDocument doc;private XmlElement root;private string fileName;public XMLManagement(){doc=new XmlDocument();}    //首先加载public bool LoadFile(string filePath){fileName=filePath;doc.Load(filePath);if(doc.InnerXml!=""){root=doc.DocumentElement;return true;}elsereturn false;}public void CreateXMLFile(string filePath) //name should contain .xml,for example "config.xml"{fileName = filePath;XmlDeclaration xmldecl;xmldecl = doc.CreateXmlDeclaration("1.0","gb2312",null);doc.AppendChild (xmldecl);root=doc.CreateElement(CarXMLConfigure.Root);doc.AppendChild(root);}    //添加节点public void setAttribute(string attriName,string attriValue){XmlElement child=doc.CreateElement(CarXMLConfigure.NetworkConfigure);child.SetAttribute(attriName,attriValue);if(root==null){Console.WriteLine("the root is null,please create it or get it from an exist xml file!");return;}root.AppendChild(child);        save();//添加节点的时候 需要保存    }public void save(){doc.Save(fileName);}    //  获取节点，public string getIP(){        //          XmlNodeList list = root.GetElementsByTagName(CarXMLConfigure.NetworkConfigure); //root.SelectNodes(CarXMLConfigure.NetworkConfigure);//        string text="";foreach(XmlNode node in list){                       XmlElement xmlnode = (XmlElement)node;            Debug.Log(node.Value + node.InnerXml + " ==  " + xmlnode.Name+" == "+xmlnode.Value +" === "+node.LocalName);            text = xmlnode.GetAttribute("IP11");//  如果跟节点相同。只能获取到第二个。。。}        Debug.Log(list.Count+" "+text);return text;}    public string getAaaryIP(int  a)    {        XmlNodeList list = root.GetElementsByTagName(CarXMLConfigure.NetworkConfigure + a.ToString());        string text = "";        foreach (XmlNode node in list)        {            text = ((XmlElement)node).GetAttribute(CarXMLConfigure.IP+a.ToString());        }        //Debug.Log(text + "  " + CarXMLConfigure.IP + a.ToString());        return text;           }    public string getMus() {        XmlNodeList list = root.GetElementsByTagName("MusConfig");        string text = "";        foreach (XmlNode node in list) {            text = ((XmlElement)node).GetAttribute("Mus");        }        return text;    }    public string getNum() {        XmlNodeList list = root.GetElementsByTagName("OthConfig");        string text = "";        foreach (XmlNode node in list)        {            text = ((XmlElement)node).GetAttribute(CarXMLConfigure.NM);        }        return text;    }    public string getN()    {        XmlNodeList list = root.GetElementsByTagName("NetConfig");        string text = "";        foreach (XmlNode node in list)        {            text = ((XmlElement)node).GetAttribute("m");        }        return text;    }    public string getNam() {        XmlNodeList list = root.GetElementsByTagName("NamConfig");        string text = "";        foreach (XmlNode node in list) {            text = ((XmlElement)node).GetAttribute("nam");        }        return text;    }    public string GetIP(string s) {        XmlNodeList list = root.GetElementsByTagName(s);        string text = "";        foreach (XmlNode node in list) {            text = ((XmlElement)node).GetAttribute(s);        }        return text;    }    public string GetIp_Name(int a)    {        XmlNodeList list = root.GetElementsByTagName(CarXMLConfigure.NetworkConfigure + a.ToString());        string text = "";        foreach (XmlNode node in list)        {            text = ((XmlElement)node).GetAttribute(CarXMLConfigure.IP + a.ToString());            text = text + "|" + ((XmlElement)node).GetAttribute("name"+a.ToString());            text = text + "|" + ((XmlElement)node).GetAttribute("num"+a.ToString());        }        //Debug.Log(text + "  " + CarXMLConfigure.IP + a.ToString());        return text;    }}

然后在其他地方调用就也可以了

using UnityEngine;using System.Collections;public class ReadXML : MonoBehaviour {    XMLManagement manager;// Use this for initializationvoid Start () {        manager = new XMLManagement();        manager.LoadFile(Application.dataPath+CarXMLConfigure.StreamingAssets+CarXMLConfigure.FileName);        string str = manager.getAaaryIP(1); //manager.getIP();        string str1 = manager.getIP();        manager.setAttribute("A","B");// 添加        Debug.Log(str +"  ===  "+str1);}// Update is called once per framevoid Update () {    }}

///  面向对象的三大特征：封装，继承， 多态

父类指针指向子类对象，然后调用父类方法
