We start with the XML Data in a string:
我们从字符串中的 XML 数据开始：
var xmlStr =
'<root><fl val="A_Value">AAAAAAAAAA</fl>' +
'<fl val="B_Value">' +
' <![CDATA["BBBBBBBB"]]>' +
'</fl>' +
'<fl val="C_Value">CCCCCCCCCC</fl>' +
'<fl val="D_Value">DDDDDDDDDD</fl></root>';
Convert the string to an XML doc object:
将字符串转换为XML 文档对象：
var parseXml;
if (window.DOMParser) {
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
} else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM")) {
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
} else {
parseXml = function() { return null; }
}
var xmlDoc = parseXml(xmlStr);
Then convert the XML doc object to JSON:
function xmlToJson(xml) {
// Create the return object
var obj = {};
// console.log(xml.nodeType, xml.nodeName );
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 ||
xml.nodeType == 4) { // text and cdata section
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);
}
if (typeof(obj[nodeName]) === 'object') {
obj[nodeName].push(xmlToJson(item));
}
}
}
}
return obj;
}
var theJson = xmlToJson(xmlDoc);
console.log(JSON.stringify(theJson));
/*
"{"root":{"fl":[{"@attributes":{"val":"A_Value"},"#text":{}},{"@attributes":{"val":"B_Value"},"#text":{},"#cdata-section":"\"BBBBBBBB\""},{"@attributes":{"val":"C_Value"},"#text":{}},{"@attributes":{"val":"D_Value"},"#text":{}}]}}"
*/
Then transform the object to your desired structure:
然后将对象转换为您想要的结构：
var transformed = {};
var elements = theJson.root.fl;
for(var i=0; i<elements.length; i++) {
var element = elements[i];
transformed[element["#text"].trim().length > 0 ?
element["#text"] :
element["#cdata-section"]] = element["@attributes"]["val"];
}
console.log(JSON.stringify(transformed));
//{"AAAAAAAAAA":"A_Value","\"BBBBBBBB\"":"B_Value","CCCCCCCCCC":"C_Value","DDDDDDDDDD":"D_Value"}

The XML to JSON Plugin(jQuery.xml2json) is a script you can use to convert simple XML into a JSON object. It will help you.
