我正在尝试创建一个图片库：

<card>
 <product catalog="Thread Works">
    <name>AK E001</name>    
    <price>45</price>
    <path>assets\cards\AK_E001.jpg</path>
 </product>

 <product catalog="Paper Work">
     <name>AK E001</name>   
    <price>45</price>
    <path>assets\cards\AK_PP003.jpg</path>
 </product>

<product catalog="Thread Works">
    <name>AK E002</name>    
    <price>50</price>
    <path>assets\cards\AK_E002.jpg</path>
 </product>

我可以访问该属性，但如果我选择“Thread Works”，我只想访问 <product catalog="Thread Works"> 子节点，以便将项目添加到数组集合中任何帮助谢谢

请参阅http://livedocs.adobe.com/flex/3/html/help.html?content=13_Working_with_XML_08.html

在你的情况下：

变量 x:XML; //用你的数据填充Xml

var threadWorks:XML = x.product.(@catalog=="Thread Works");

编辑：警告：不要忘记 . 在产品和@catalog 之间

function onXmlLoaded (e:Event):void 
{
    xml = XML(e.target.data);
    var xmlLength:Number  = xml.product.length();
    for(var i:uint = 0; i<xmlLength; i++)
    {
            dataContainer.push( {
            catalog : xml.product.@catalog,
            name :  xml..name,
            price : xml..price,
            path : xml..path
        });
    }
    for(i=0;i<dataContainer.length;i++)
    {
           if(dataContainer[i].catalog[0]== "your String"){
                 showName();
           }
    }
}
