如何从XML中的所有子体中删除特定属性？

我有一个类似XML的

var test:XML = new XML( <record id="5" name="AccountTransactions"
    <field id="34" type="Nuber"/>
    </record>);

它仍然显示所有属性：///p>

var-xml:xml=new-xml(
var xml:XML = new XML(
    <record id="5" name="AccountTransactions">
        <field id="34" type="Number">
            <test id="0"/>
        </field>
    </record>);

//make array of attribute keys, excluding "id" and "type"
var attributesArray:Array = new Array();
for each (var attribute:Object in xml.attributes())
{
    var attributeName:String = attribute.name();
    if (attributeName != "id" && attributeName != "type")
    {
        attributesArray.push(attributeName);
    }
}

//loop through filtered attributes and remove them from the xml
for each (var attributeKey:String in attributesArray)
{
    delete xml.@[attributeKey];
    delete xml.descendants().@[attributeKey];
}

);
//生成属性键数组，不包括“id”和“type”
var attributesArray:Array=new Array（）；
对于每个（var属性：xml.attributes（）中的对象）
{
var attributeName:String=attribute.name（）；
if（attributeName！=“id”&&attributeName！=“type”）
{
属性数组推送（attributeName）；
}
}
//循环过滤属性并将其从xml中删除
对于每个（var attributeKey:AttributeArray中的字符串）
{
删除xml@[attributeKey]；
删除xml.subjects（）@[attributeKey]；
}

var测试：XML=newxml（“”）；
var属性：XMLList=test.field@*；
变量长度：int=attributes.length（）；
对于（变量i:int=0；i

您可以发布您的确切xml结构吗？我们可以在不使用循环的情况下执行此操作吗？正如我在上面的代码中尝试的那样。我需要解析一个非常大的XML。。循环需要时间

var xml:XML = new XML(
    <record id="5" name="AccountTransactions">
        <field id="34" type="Number">
            <test id="0"/>
        </field>
    </record>);

//make array of attribute keys, excluding "id" and "type"
var attributesArray:Array = new Array();
for each (var attribute:Object in xml.attributes())
{
    var attributeName:String = attribute.name();
    if (attributeName != "id" && attributeName != "type")
    {
        attributesArray.push(attributeName);
    }
}

//loop through filtered attributes and remove them from the xml
for each (var attributeKey:String in attributesArray)
{
    delete xml.@[attributeKey];
    delete xml.descendants().@[attributeKey];
}

    var test:XML = new XML( '<record id="5" name="AccountTransactions"><field id="34" type="Nuber" score="ded"/><field id="35" type="Nuber" score="sc"/></record>');
    var attributes:XMLList = test.field.@*;
    var length:int = attributes.length();
    for (var i:int = 0; i < length; i++) {
        (attributes[i].localName() != "id" && attributes[i].localName() != "type") ? [delete attributes[i], length--] : void;
    }
    trace(test);
