FLEX 合并两个XML的属性

例如：

oldXml

<object datePoint="2011-03-05" PT_staticCount="3" UOC_staticCount="3"/>
<object datePoint="2011-03-06" PT_staticCount="5" UOC_staticCount="9"/>
<object datePoint="2011-03-07" PT_staticCount="9" UOC_staticCount="7"/>
<object datePoint="2011-03-08" PT_staticCount="15" UOC_staticCount="9"/>
<object datePoint="2011-03-09" PT_staticCount="6" UOC_staticCount="5"/>
<object datePoint="2011-03-10" PT_staticCount="6" UOC_staticCount="4"/>

newXml

<object datePoint="2011-03-05" UOC_staticCount="3"/>
<object datePoint="2011-03-06" UOC_staticCount="9"/>
<object datePoint="2011-03-07" UOC_staticCount="7"/>
<object datePoint="2011-03-08" UOC_staticCount="9"/>
<object datePoint="2011-03-09" UOC_staticCount="5"/>
<object datePoint="2011-03-10" UOC_staticCount="4"/>

可以是用如下函数进行合并

private function mergeTwoXml(oldXml:XMLList, newXml:XMLList, propertyInNewXMl:String):XMLList
{
	for(var i:int = 0; i < oldXml.length(); i++)
	{
		oldXml[i].@[propertyInNewXMl+"_staticCount"] = newXml[i].attribute(propertyInNewXMl+"_staticCount");
	}
　　  return oldXml;
}

输出的内容为：

<object datePoint="2011-03-05" PT_staticCount="3" UOC_staticCount="3"/>
<object datePoint="2011-03-06" PT_staticCount="5" UOC_staticCount="9"/>
<object datePoint="2011-03-07" PT_staticCount="9" UOC_staticCount="7"/>
<object datePoint="2011-03-08" PT_staticCount="15" UOC_staticCount="9"/>
<object datePoint="2011-03-09" PT_staticCount="6" UOC_staticCount="5"/>
<object datePoint="2011-03-10" PT_staticCount="6" UOC_staticCount="4"/>
