我的
XML文件格式如下.
<markers>
<marker>
<type></type>
<title></title>
<address></address>
<latitude></latitude>
<longitude></longitude>
<marker>
<marker>
<type></type>
<title></title>
<address></address>
<latitude></latitude>
<longitude></longitude>
<marker>
</markers>
请建议我如何阅读所有“标记”元素.
我需要获得“标记”的所有子元素的值
谢谢
解决方法
下面的代码将任何XMLObject或字符串转换为本机JavaScript对象.然后,您可以在对象上行走以提取您想要的任何值.
/**
* Tries to convert a given XML data to a native JavaScript object by traversing the DOM tree.
* If a string is given,it first tries to create an XMLDomElement from the given string.
*
* @param {XMLDomElement|String} source The XML string or the XMLDomElement prefreably which containts the necessary data for the object.
* @param {Boolean} [includeRoot] Whether the "required" main container node should be a part of the resultant object or not.
* @return {Object} The native JavaScript object which is contructed from the given XML data or false if any error occured.

Object.fromXML = function( source,includeRoot ) {
if( typeof source == 'string' )

if ( window.DOMParser )
source = ( new DOMParser() ).parseFromString( source,"application/xml" );

xmlObject.async = false;
xmlObject.loadXML( source );
source = xmlObject;
xmlObject = undefined;
