我正在尝试使用JQuery将sitemap.xml解析为这样的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>
我提出的方法避免了设置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/
:
它获取第一个[0]元素,www.example.com
这是第1级,因此检查是否有ul[id=1]
,如果没有,则运行create_ul
并将其附加到#content
}。现在将li
附加到它刚刚创建的ul
上。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
的原因。
对于下一个元素[1],它得到brand
,它是2级。这次检查
是否存在li[id=www.example.com] ul[id=2]
,如果存在,则会创建一个,然后将li
附加到ul
。
这种方法根本不适用于我,如果说8级具有相同的id和4级的东西,它也会变得混乱。我只需要一个关于如何处理它的新想法。
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
答案 0 :(得分:1)
这是我的尝试。
基本上它使用数组来存储所有网址的件
例如,网址mytest.url.com/sub1/othersub2.html
的处理方式为:
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):
<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>
