Question

我一直在使用这个XML，但我无法获得带元素运算符的节点列表：

<s:LinearGradient rotation="90" xmlns:s="library://ns.adobe.com/flex/spark">
  <s:GradientEntry color="0x000000" alpha="0.8"/>
  <s:GradientEntry color="0xFFFFFF" alpha="0.8"/>
</s:LinearGradient>

这是我的AS3：

var fillXML:XML = <s:LinearGradient rotation="90" xmlns:s="library://ns.adobe.com/flex/spark">
      <s:GradientEntry color="0x000000" alpha="0.8"/>
      <s:GradientEntry color="0xFFFFFF" alpha="0.8"/>
    </s:LinearGradient>;

var entriesXML:XMLList;
var GRADIENT_ENTRY:String = "GradientEntry";
entriesXML = fillXML..entries;

if (entriesXML.length()==0) {
    entriesXML = fillXML.descendants(GRADIENT_ENTRY);

    if (entriesXML.length()==0) {
        entriesXML = fillXML.elements(GRADIENT_ENTRY);
    }
}

看起来您必须使用QName对象进行搜索：

var fillXML:XML = <s:LinearGradient rotation="90" xmlns:s="library://ns.adobe.com/flex/spark">
      <s:GradientEntry color="0x000000" alpha="0.8"/>
      <s:GradientEntry color="0xFFFFFF" alpha="0.8"/>
    </s:LinearGradient>;

var entriesXML:XMLList;
var GRADIENT_ENTRY:String = "GradientEntry";
var qname:QName = new QName("library://ns.adobe.com/flex/spark", GRADIENT_ENTRY);

entriesXML = fillXML.elements(GRADIENT_ENTRY);;

if (entriesXML.length()==0) {
    entriesXML = fillXML.elements(qname);
}

使用elements运算符时，无法从XML对象获取元素列表？
