     <image name="PageDown" src="Template/1/img/7.png" x="350" y="50"></image>
</bg>  
用QXmlStreamReader读取这个
文件后
<nodes x="50" y="60" rows="1" cols="4">
          <img src="Template/1/img/5.png" margin="10,10,100,100"></img>
          <text size="30" bold="true" family="Courier" color="#FF0000" margin="20,30,100,500" >{Title}</text>
     </nodes>
我想根据rows="1" cols="4"属性值循环多个<nodes>   求高手解答
