XML读取的几种方式

编写一个XML文件如下：

xml version=“1.0” encoding=“utf-8”?>
<Xml>
    <JD>
        <Name>节点01Name>
        <X>001X>
        <Y>002Y>
    JD>
    <JD>
        <Name>节点02Name>
        <X>003X>
        <Y>004Y>
    JD>
    <JD>
        <Name>节点03Name>
        <X>005X>
        <Y>006Y>
    JD>
Xml>

    
        节点01
        001
        002
    
    
        节点02
        003
        004
    
    
        节点03
        005
        006
    

接下来Unity中写代码：

第一种方式

通过GetElementsByTagName直接获取节点，返回类型是XmlNodeList数组，数组包括了这个节点的所有内容

代码如何：

using UnityEngine;
using System.Collections;
using System.Xml;

public class DJH_Read : MonoBehaviour {

    // Use this for initialization
    void Start () {
        string url = Application.dataPath + “/MyTest.xml”;
        XmlDocument XmlDoc=new XmlDocument();
        XmlDoc.Load(url);

        int XmlCount = XmlDoc.GetElementsByTagName(“JD”)[0].ChildNodes.Count;

        for (int i = 0; i < XmlCount; i++)
        {
            string NameValue = XmlDoc.GetElementsByTagName(“JD”)[0].ChildNodes[i].InnerText;
            Debug.Log(NameValue);
        }

    }

}

using UnityEngine;
using System.Collections;
using System.Xml;

public class DJH_Read : MonoBehaviour {

    // Use this for initialization
    void Start () {
        string url = Application.dataPath + "/MyTest.xml";
        XmlDocument XmlDoc=new XmlDocument();
        XmlDoc.Load(url);

        int XmlCount = XmlDoc.GetElementsByTagName("JD")[0].ChildNodes.Count;

        for (int i = 0; i < XmlCount; i++)
        {
            string NameValue = XmlDoc.GetElementsByTagName("JD")[0].ChildNodes[i].InnerText;
            Debug.Log(NameValue);
        }

    }

}

输出后结果：

第二种方式

通过foreach查找所有目标名称的子节点

代码如下：

using UnityEngine;
using System.Collections;
using System.Xml;

public class DJH_Read : MonoBehaviour {

    // Use this for initialization
    void Start () {
        string url = Application.dataPath + “/MyTest.xml”;
        XmlDocument XmlDoc=new XmlDocument();
        XmlDoc.Load(url);

        XmlNodeList nodeList = XmlDoc.SelectSingleNode(”Xml”).ChildNodes;
        foreach (XmlElement xe in nodeList)
        {
            foreach (XmlElement xxe in xe.ChildNodes)
            {
                if (xxe.Name == “Name”)
                {
                    Debug.Log(xxe.InnerText);
                }
            }
        }
    }

}

using UnityEngine;
using System.Collections;
using System.Xml;

public class DJH_Read : MonoBehaviour {

    // Use this for initialization
    void Start () {
        string url = Application.dataPath + "/MyTest.xml";
        XmlDocument XmlDoc=new XmlDocument();
        XmlDoc.Load(url);

        XmlNodeList nodeList = XmlDoc.SelectSingleNode("Xml").ChildNodes;
        foreach (XmlElement xe in nodeList)
        {
            foreach (XmlElement xxe in xe.ChildNodes)
            {
                if (xxe.Name == "Name")
                {
                    Debug.Log(xxe.InnerText);
                }
            }
        }
    }

}

输出后结果：
