AS3之解析XML

范例代码:

var xml:XML= <data>
  <item name="cat" id="1" type="pet" />
  <item name="starling" id="1" type="animal" />
  <item name="mouse" id="1" type="animal" /> 
  <item name="dog" id="1" type="pet" />
</data>

目的:要得到type为pet的name,用@type属性找,注意写法带圆括号,包含@ .(@type == 'pet')

var xml2:XMLList = xml.item.(@type == 'pet');
for (var i:*  in xml2) 
{
	trace(i,xml2[i]);
}

trace得到

0
1

怎样得到name的值呢?

-->toString......转成字符串,读出来

var xml2:XMLList = xml.item.(@type == 'pet');
for (var i:*  in xml2) 
{ 
	trace(i,xml2[i].toString());
}

trace得到

0
1

读不出来?-->撕碎XML，暴力解决!......

var str:String = xml.item.(@type == 'pet').toString();
trace(str);
var arr:Array = str.split('n');
trace(arr.length);
for (var i:int = 0; i < arr.length; i++) 
{ 
	var txt:String = arr[i];
	
	txt = String(txt.split(' ')[1]);
	txt = txt.substring('name="'.length,txt.length - 1); 
	trace(txt);
}

trace得到

<item name="cat" id="1" type="pet"/>
<item name="dog" id="1" type="pet"/>
2
cat
dog

神啊，请赐予我力量，奥特曼~~

记住这个：toXMLString()

var xml2:XMLList = xml.item.(@type == 'pet');
for (var i:*  in xml2) 
{
	trace(i,xml2[i].toXMLString());
}

trace得到

0 <item name="cat" id="1" type="pet"/>
1 <item name="dog" id="1" type="pet"/>

name呢----〉用属性标签

var xml2:XMLList = xml.item.(@type == 'pet');
for (var i:*  in xml2) 
{
	trace(i,xml2[i].@name);
}  

trace得到

0 cat
1 dog
