我试图使用JQuery解析sitemap.xml看起来像这样的HTML：http://astuteo.com/slickmap/demo/

经过几个小时的努力,我觉得我真的需要一些正确方向的帮助.

它具有的主要模板是这样的,其中每个缩进是不同的目录级别：

<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>

我使用的是google sitemap.xml,如下所示：

http://meyers.ipalaces.org/sitemap_000.xml

<url> 
  <loc>http://meyers.ipalaces.org/</loc> 
  <lastmod>2011-02-26T09:32:18Z</lastmod> 
  <changefreq>hourly</changefreq> 
  <priority>0.4</priority> 
</url> 
<url> 
  <loc>http://meyers.ipalaces.org/meyers/photos/Explorer</loc> 
  <lastmod>2011-02-26T09:31:33Z</lastmod> 
  <changefreq>hourly</changefreq> 
  <priority>0.2</priority> 
</url> 

我提出的方法避免设置css模板上的所有内容,但我只是专注于让它具有正确的级别：

它的作用是使URL的级别通过每个级别尝试基于先前级别创建列表.所以使用示例www.example.com/brand/model/product/：

它得到第一个[0]元素,www.example.com这是1级,所以检查是否有ul [id = 1],如果没有则运行create_ul并将其附加到#content.现在将一个li附加到它刚刚创建的ul.级别1是“特殊的”,因为它必须首先创建,这就是为什么我在代码中有很多if level == 1.

对于下一个元素[1],它获得了2级的品牌.这次它检查
是否有li [id = www.example.com] ul [id = 2]如果存在,它将创建一个然后将li附加到ul.

这个方法根本不适合我,如果说8级具有相同的id和4级的东西,它也会混乱.我只需要一个关于如何处理这个问题的新想法.

这是我现在的功能,但我确定我应该废弃大部分代码：

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

        if(level==1) {
            $('#content').append(ul);
        } else {
            $('ul[id='+(level-1)+'] li[id='+prev_id+']').append(ul);
        }
}



function create_li(level, id, prev_id){
    if (level ==1){
        if ($('ul[id='+level+']').length == 0) {
            create_ul(level, id, prev_id);
        } else if ($('ul[id='+level+'] li[id='+id+']').length > 0) {
            return;
        }

        var li = $('<li/>',{
            id: id
        });

        var a = $('<a/>',{
            text:   level + " - " + id,
            href:  "nothing yet"
        });

        $('ul[id='+level+']').append(li);
        return;
    } 
    // If there is no UL for the LI, create it
    if ($('li[id='+prev_id+'] ul[id='+level+']').length == 0) {
        create_ul(level, id, prev_id);
    } else if ($('ul[id='+level+'] li[id='+id+']').length > 0) {
        return;
    }

    var li = $('<li/>',{
        id: id
    });


        var a = $('<a/>',{
            text:   level + " - " + id,
            href:  "nothing yet"
        });

    li.append(a);


    $('li[id='+prev_id+'] ul[id='+level+']').append(li);
}

$.ajax({  
    type: "GET",  
    url: "/sitemap_000.xml",  
    dataType: "xml",  
    success: parseXml  
});  

function parseXml(xml) {   
    URLS = new Array(new Array(), new Array(), new Array());
    $(xml).find("loc").each(function(){
        var url = $(this).text();
        URLS[1].push(url);

        url = url.replace("http://", "")
        var url_array = url.split("/");

        URLS[0].push(url_array);

        var rawLastMod = $(this).parent().find('lastmod').text();  
        var timestamp = rawLastMod.replace(/T.+/g, '');
        var lastMod = formatDate(timestamp);


        URLS[2].push(lastMod);
    });



    $(URLS[0]).each(function(i, url_array){
        $(url_array).each(function(index, fragment){
            var level = index+1;
            var id = fragment;
            if(index!=0) {
                var prev_id = URLS[0][i][index-1];
            } else {
                var prev_id = null;
            }

            if(id != "") {                                          
                create_li(level, id, prev_id);
            }
        });
    });
}

我决定回复PHP解决方案而不是Javascript.我正在使用这个PHP脚本：http://www.freesitemapgenerator.com/xml2html.html

解决方法:

这是我的尝试.

基本上它使用数组来存储所有网址的部分.
例如,网址mytest.url.com/sub1/othersub2.html的处理方式如下：

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(只需替换你的parseXml函数并使用firebug在chrome或firefox上测试它)：

<script type="text/javascript">
function parseXml(xml) {
    //here we will store nested arrays representing the urls
    var map = []; 
    $(xml).find("loc").each(function () {
        //some string cleaning due to bad urls provided
        //(ending slashes or double slashes)
        var url = this.textContent.replace('http://', '').replace('//', ''),
            endingInSlash = (url.substr(url.length - 1, 1) == '/'),
            cleanedUrl = url.substr(0, url.length - (endingInSlash ? 1 : 0)),
            splittedUrl = cleanedUrl.split('/'),  //splitting by slash
            currentArrayLevel = map; //we start from the base url piece

        for (var i = 0; i < splittedUrl.length; i++) {
            var tempUrlPart = splittedUrl[i];
            //in javascript you can index arrays by string too!
            if (currentArrayLevel[tempUrlPart] === undefined) {
                currentArrayLevel[tempUrlPart] = [];
            }
            currentArrayLevel = currentArrayLevel[tempUrlPart];
        }
    });

    var currentUrlPieces = [];  //closure to the recursive function
    (function recursiveUrlBuilder(urlPiecesToParse) {
        //build up a DOM element with the current URL pieces we have available
        console.log('http://' + currentUrlPieces.join('/'));  

        for (var piece in urlPiecesToParse) {
            currentUrlPieces.push(piece);
            //recursive call passing the current piece
            recursiveUrlBuilder(urlPiecesToParse[piece]);  
        }
        //we finished this subdirectory, so we step back by one
        //by removing the last element of the array
        currentUrlPieces.pop();   
    })(map);
}
</script>
