使用整数名称访问 XML 节点 [英] Access XML nodes with integer names

问题描述

对于我的应用程序，我发出一个 HTTPRequest，并从 JSP 获取一些 XML.XML 有一些(是的，我知道这是无效/不正确的 XML.如果我找不到创可贴，我将尝试在内部解决该问题)以整数作为名称的节点，例如 <2> 例如.

For my application, I make an HTTPRequest, and get back some XML served from a JSP. That XML has some (yes, I'm aware this is invalid/improper XML. If I can't find a bandaid, I will try to address that internally) nodes with integers as names, say <2> for example.

当我尝试使用 myXMLVariable.child("2") 访问它时，它返回第三个 (index=2) XML 节点.我知道这种行为是 "正确".有什么办法可以避免这种行为吗?

When I attempt to access it, using myXMLVariable.child("2"), it returns the third (index=2) XML node instead. I understand that this behavior is "correct". Is there any way to get around this behavior?

var myXML:String = "<response>" +
                    "<place1>" +
                    "   <item>1</item>" +
                    "   <stuff>1</stuff>" +
                    "</place1>" +
                    "<2>" +
                    "   <item>1</item>" +
                    "   <stuff>1</stuff>" +
                    "</2>" +
                    "<place3>" +
                    "   <item>1</item>" +
                    "   <stuff>1</stuff>" +
                    "</place3>" +
                    "</response>";

protected function getParam():void
{
    var xml:XML = new XML(myXML);
    
    Alert.show(xml.child("2"));
    //trace(xml.child("2"))
}

xml.child("2") 返回

<place3>
    ...
</place3>

...当我想要时

<2>
    ...
</2>

注意

我知道这是无效的 XML.我正在寻找一种解决方法，即短期修复.有一个近期的发布日期，此变通方法将被删除并替换为下一个版本的适当 XML.

NOTE

I am aware this is invalid XML. I am looking for a workaround, a short term fix. There is a near-future release date, and this workaround will be removed and replaced with proper XML for the next version.

推荐答案

在 XMLList 上使用 E4X 搜索表达式.

Use E4X search expression on XMLList.

trace(xml.children().(name() == "2").toXMLString());

1. 获取所有孩子
2. 搜索您需要的 name().
