Javascript 将XML解析为UL

我正在尝试使用JQuery解析sitemap.xml，使其看起来像以下HTML：

经过几个小时的努力，我决定在正确的方向上我真的需要一些帮助

它的主要模板是这样的，其中每个缩进都是不同的目录级别：

<ul id="primaryNav" class="col4">
    <li id="home"><a href="http://sitetitle.com">Home</a></li>
    <li><a href="/services">Services</a>
        <ul>
            <li><a href="/services/design">Graphic Design</a></li>
            <li><a href="/services/development">Web Development</a></li>
            <li><a href="/services/marketing">Internet Marketing</a>
                <ul>
                    <li><a href="/social-media">Social Media</a></li>
                    <li><a href="/optimization">Search Optimization</a></li>
                    <li><a href="/adwords">Google AdWords</a></li>
                </ul>
            </li>
            <li><a href="/services/copywriting">Copywriting</a></li>
            <li><a href="/services/photography">Photography</a></li>
        </ul>
    </li>
</ul>

我决定用PHP解决方案而不是Javascript来回复。我正在使用这个PHP脚本：

这是我的尝试

基本上，它使用一个数组来存储所有URL的片段。
例如，url

mytest.url.com/sub1/othersub2.html

被处理为：

var map = ['mytest.url.com']['sub1']['othersub2.html'];

这是可能的，因为javascript允许您使用字符串索引数组

完整代码（只需替换您的

parseXml

函数，并使用firebug在chrome或firefox上进行测试）：

函数解析xml（xml）{
//这里我们将存储表示URL的嵌套数组
var-map=[]；
$（xml）.find（“loc”）.each（函数（）{
//由于提供了错误的URL，某些字符串被清除
//（结束斜杠或双斜杠）
var url=this.textContent.replace（'http://'，''）.replace（'//'，''），
endingislash=（url.substr（url.length-1,1）='/'），
cleanedUrl=url.substr（0，url.length-（endingSlash？1:0）），
splittedUrl=cleanedUrl.split（'/'），//按斜杠拆分
currentArrayLevel=map；//我们从基本url开始
对于（var i=0；i

有人可以向我解释为什么没有将代码正确地突出显示为“javascript”？编辑：好的，通过添加

标记来欺骗它。

function create_ul(level, id, prev_id) {
        var ul = $('<ul/>',{
            id: level
