解析与AS3

Question

自定义XML我有一个XML，我并没有找到一种方法如何解析它（读取里面的数据）

<Saa:Header> 
     <Saa:Message> 
      <Saa:SenderReference> data 
      </Saa:SenderReference> 
     </Saa:Message> 
     <Saa:Message> 
      <Saa:SenderReference> data 
      </Saa:SenderReference> 
     </Saa:Message> 
    </Saa:Header> 

我使用AS3语言

你的榜样在你的问题去（假定你的data是一个字符串），你可以做一些沿着这些路线：

//your xml needs a namespace identifier to be valid 
//I've added one on the header node. 
//Likely if you're consuming this xml from some third party, the namespace declaration will be on root node. 
var myXML = <Saa:Header xmlns:Saa="urn:swift:saa:xsd:saa.2.0" > 
     <Saa:Message> 
      <Saa:SenderReference> data 
      </Saa:SenderReference> 
     </Saa:Message> 
     <Saa:Message> 
      <Saa:SenderReference> data 
      </Saa:SenderReference> 
     </Saa:Message> 
    </Saa:Header>; 

//create a reference to the `Saa` namespace that prefixes all your xml nodes 
var saaNamespace:Namespace = new Namespace("urn:swift:saa:xsd:saa.2.0"); 

//tell AS3 to use that namespace by default 
default xml namespace = saaNamespace; 

//basically an array of all the SenderReference nodes in the entire xml 
var xmlList:XMLList = myXML..SenderReference; 

//This line will give the same results as the line above, but if there were SenderReference nodes somewhere else in the document that weren't under Message nodes, they would not be included (unlike above) 
xmlList = myXML.Message.SenderReference; 

//iterate through all the SenderReference nodes 
for(var i:int=0;i<xmlList.length();i++){ 
    trace("Node #" + (i+1) + ":",xmlList[i]); 
} 

有很多方法可以让你从想要的数据在AS3中的XML，一篇好文章is this one from senocular。

The XML class is the way.

[它]包含使用XML对象的方法和属性。 XML类（以及XMLList，Namespace和QName类）实现了ECMAScript for XML（E4X）规范（ECMA-357第2版）中定义的强大的XML处理标准。
