在 AS3 中将 XMLDocument 转换为 E4X？

Question

我正在尝试将某些 AS2 XML 代码转换为以下 E4X. I have the following code original XML (now XMLDocument) 语法：

//temp var used to access createElement and creatTextNode 
var tempXML:XML = new XML(); 

//make an element:  <myNodeName> 
var myNode:XMLNode = tempXML.createElement("myNodeName"); 

//make a text node: "myValue" 
var myTextNode = tempXML.createTextNode("myValue"); 

//put the text node into the element: <myNodeName>myValue</myNodeName> 
myNode.appendChild( myTextNode ); 

//test it 
trace( myNode.toString() );

如果我用 E4X 编写它，等效的是什么？

我特别希望在 E4X 中重现 createElement() 和 createTextNode() 函数。

Answer 1

var myNode = <myNodeName>myValue</myNodeName> 是您从字面上构造它所需要的全部。如果您将内容作为字符串变量，则使用 var myNode = <myNodeName>{yourVariable}</myNodeName>.

示例：

    public function ASTest() 
    {
        var xmlDocument:String = testXMLDocument();
        var e4x:String = testE4X();
        trace("xmlDocument: "+xmlDocument);
        trace("e4x: "+e4x);

        trace("assert true: " + (xmlDocument == e4x));
    }

    public function testXMLDocument():String 
    {
        //temp var used to access createElement and creatTextNode 
        var tempXML:XMLDocument = new XMLDocument(); 

        //make an element:  <myNodeName> 
        var myNode:XMLNode = tempXML.createElement("myNodeName"); 

        //make a text node: "myValue" 
        var myTextNode:XMLNode = tempXML.createTextNode("myValue"); 

        //put the text node into the element: <myNodeName>myValue</myNodeName> 
        myNode.appendChild( myTextNode ); 

        //test it 
        return myNode.toString();       
    }

    public function testE4X():String 
    {
        //make an element:  <myNodeName> 
        var myNode:XML = <myNodeName />;


        /**
         * put the text node into the element: <myNodeName>myValue</myNodeName>
         * Two options to achieve that:
         *  1) using methods of XML class
         *  2) using e4k operators
         * Both ways give the same result
         */

        //1) XML function usage:
        //myNode.appendChild("myValue");

        //2) e4x syntax
        myNode.* += "myValue";

        //test it 
        return myNode.toXMLString();        
    }

输出：

xmlDocument: <myNodeName>myValue</myNodeName>
e4x: <myNodeName>myValue</myNodeName>
assert true: true
