如何使用javascript JQuery解析XML结构

This is the XML File:

这是XML文件：

<Test>
    <Category>
        <SubCat>
            <Name>Name</Name>
            <Properties>
                <Key>Key</Key>
                <Value>Value</Value>
            </Properties>
        </SubCat>
        <SubCat>
            <Name>Name</Name>
            <SubCat>
                <Name>AnotherName</Name>
                <Properties>
                    <Key>Key</Key>
                    <Value>Value</Value>
                </Properties>
            </SubCat>
        </SubCat>
    </Category>
</Test>

I would like to get the Name. But only the Name of the first SubCat. And the properties key value. The problem is the SubCat exist two times.

我想得到这个名字。但只有第一个SubCat的名称。和属性键值。问题是SubCat存在两次。

I tried this:

我试过这个：

$(xml).find('SubCat').each(function() {
    var name = $(this).find("Name").text();
    alert(name);

}

but this show the name of the first and the second SubCat.

但这显示了第一个和第二个SubCat的名称。

i search for something like this.

我搜索这样的东西。

rootElement(Category).selectallchildren(SubCat).Name for the first SubCat Name
rootElement(Category).selectallchildren(SubCat).(SubCat).Name for the second SubCat Name

And same explicit select for the Key and values

并且明确选择Key和值

The trick here is to make use of jQuery's ability to evaluate CSS3 selectors.

这里的技巧是利用jQuery评估CSS3选择器的能力。

SubCat:nth-of-type(1) selects every first occurrence of SubCat with arbitrary parent elements.

SubCat：nth-of-type（1）选择具有任意父元素的每个第一次出现的SubCat。

So this should work:

所以这应该工作：

$(xml).find("SubCat:nth-of-type(1)").each(function(){
    var name = $(this).find("Name").text(),
        property = { };    //use an object to store the key value tuple
    property[$(this).find("Properties Key").text()] = $(this).find("Properties Value").text();

    console.log(name, property);
});

//Output:
//Name Object { Key="Value" }
//AnotherName Object { Key="Value"}

Hopefully that's what you want; when writing my first answer I obviously misinterpreted your question, sorry for the confusion...

希望这就是你想要的;在写我的第一个答案时，我显然误解了你的问题，抱歉这个混乱......
