XML读取的几种方式

编写一个XML文件如下：

[html] view plain copy print?<?xml version=“1.0” encoding=“utf-8”?>
<Xml>
<JD>
<Name>节点01</Name>
<X>001</X>
<Y>002</Y>
</JD>
<JD>
<Name>节点02</Name>
<X>003</X>
<Y>004</Y>
</JD>
<JD>
<Name>节点03</Name>
<X>005</X>
<Y>006</Y>
</JD>
</Xml>

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

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：

[csharp] view plain copy print?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：

[csharp] view plain copy print?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：
