xml转json的js代码，需要的朋友可以参考下

function xmlToJson(xml) { 
// Create the return object 
var obj = {}; 

if (xml.nodeType == 1) { // element 
// do attributes 
if (xml.attributes.length > 0) { 
obj["@attributes"] = {}; 
for (var j = 0; j < xml.attributes.length; j++) { 
var attribute = xml.attributes.item(j); 
obj["@attributes"][attribute.nodeName] = attribute.nodeValue; 
} 
} 
} else if (xml.nodeType == 3) { // text 
obj = xml.nodeValue; 
} 

// do children 
if (xml.hasChildNodes()) { 
for (var i = 0; i < xml.childNodes.length; i++) { 
var item = xml.childNodes.item(i); 
var nodeName = item.nodeName; 
if (typeof (obj[nodeName]) == "undefined") { 
obj[nodeName] = xmlToJson(item); 
} else { 
if (typeof (obj[nodeName].length) == "undefined") { 
var old = obj[nodeName]; 
obj[nodeName] = []; 
obj[nodeName].push(old); 
} 
obj[nodeName].push(xmlToJson(item)); 
} 
} 
} 
return obj; 
};
