JavaScript method to convert XML to JSON_javascript skills

The example in this article describes how JavaScript converts XML to JSON. Share it with everyone for your reference. The specific method is as follows:

1. The JavaScript code is as follows:

Copy code The code is as follows:

// 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 < 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;
};

2. XML code:
