下面是XML文件

<?xml version="1.0" encoding="utf-8"?>
<PSScene>
<Layers>
	<Layer>
		<name>Layer 1</name>
		<Path>Group 5/Group 4/Group 3/Group 2/Group 1/Layer 1</Path>
		<Posx>-33</Posx>
		<Posy>38</Posy>
		</Layer>
	<Layer>
		<name>my channel</name>
		<Path>Group 5/Group 4/Group 3/Group 2/Group 1/my channel</Path>
		<Posx>44</Posx>
		<Posy>41.5</Posy>
		</Layer>
	<Layer>
		<name>my layer</name>
		<Path>Group 5/Group 4/Group 3/Group 2/Group 1/my layer</Path>
		<Posx>0</Posx>
		<Posy>1.5</Posy>
		</Layer>
	<Layer>
		<name>my channel copy</name>
		<Path>my channel copy</Path>
		<Posx>-43</Posx>
		<Posy>-51.5</Posy>
	</Layer>
	<Layer>

		<Path>my layer copy</Path>
		<Posx>46</Posx>
		<Posy>-51.5</Posy>
	</Layer>
</Layers>
</PSScene>

如果节点处为属性则代码为这样

XmlNode actionNode = list.ChildNodes[i];
lieBiao.name=actionNode.Name;
XmlAttribute guodu = actionNode.Attributes["guodu"];
lieBiao.guodu=int.Parse(guodu.InnerText);
Debug.Log(guodu.InnerText);
XmlAttribute miaoshu = actionNode.Attributes["miaoshu"];
lieBiao.miaoshu=miaoshu.InnerText;
