JavaScript将XML转成JSON的方法_javascript技巧

// Changes XML to JSON
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                 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             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;
