js如何解析xml字符串？
如下xml字符串：
--------------------------------------
<markers>
<marker carId="1" carName="SHANGHAI" gpsTime="2011-08-26 21:21:11.0" lat="31.230393" lng="121.473704" direction="222" speed="22" />
<marker carId="7" carName="XIAMEN" gpsTime="2011-08-26 21:21:11.0" lat="24.479836" lng="118.089421" direction="222" speed="22" />
</markers>
---------------------------------------
如何解析？
----------------------------------------
提示：我在网上看到的js解析xml字符串方法，xml字符串都是如下格式，
上面的格式怎么解析？
<NewInfo>
<News>
<Title>今天要下雨</Title>
<Content>今天确实下雨了</Content>
<Date>2009-02-04</Date>
</News>
<News>
<Title>今天出太阳</Title>
<Content>今天确实出太阳了</Content>
<Date>2009-02-03</Date>
</News>
</NewInfo>

[解决办法]
都有例子你还不会啊；
var items = xmlDoc.getElementsByTagName("marker");
alert(items.length);
for(var i=0;i<items.length;i++){
var x = items[i];
alert(x.getAttribute("carId"));
alert(x.getAttribute("carName"));
}

<script type="text/javascript">
function parseXML()
{
text="<note>";
text=text+"<to>George</to>";
text=text+"<from>John</from>";
text=text+"<heading>Reminder</heading>";
text=text+"<body>Don't forget the meeting!</body>";
text=text+"</note>";
try //Internet Explorer
{
xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.loadXML(text);
}
catch(e)
{
try //Firefox, Mozilla, Opera, etc.
{
parser=new DOMParser();
xmlDoc=parser.parseFromString(text,"text/xml");
}
catch(e)
{
alert(e.message);
return;
}
}
document.getElementById("to").innerHTML=xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
document.getElementById("from").innerHTML=xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;
document.getElementById("message").innerHTML=xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;
}

<p>

这个可以 已经测试过了

【JS读取XML并显示各节点[兼容IE/FF/Chrome,Safari]】
[解决办法]
XML和HTML获取差不多，你先获取<NewInfo>,var oNewInfo = document.getElementsByTagName('NewInfo'),然后获取<News>，var oNews = document.getElementsByTagName('Nwes');
alert(oNews.length) 应该是2
[解决办法]
还是用jQuery吧， 比较简洁点
