//例子一:
var example:XML = <person/>;
example.father = <father/>; //内容属性和元素名称不一定要相同,也可以: example.abc = <father/>,但会以元素名称为准,即会建立一个<father/>元素
trace(example);
/*
输出:
<person>
<father/>
</person>
*/
//例子二:
var example:XML = <person/>;
example.father = “”; //建立一个<father/>元素
trace(example.toString());
/*
输出:
<person>
<father/>
</person>
*/
//例子三:
var example:XML = <person/>;
var id:int = 10;
example["user" + id] = “”;
trace(example);
/*
输出:
<person>
<user10/>
</person>
注意: 有些情况必须使用第三种情况.例如,元素节点名称内含连字符(“-”)是完全合法的,但在ActionScript里会得到编译器错误:
example.some-element = “”; //产生编译器错误
正确的写法是:
example["some-element"] = “”;
