下面是神奇的XML转JSON的javascript代码:
// Changes XML to JSONfunction 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;};下面的XML为:
通过上面的函数转换后的JSON为:
{ "@attributes": { AID: "=", HOME: 0, URL: "davidwalsh.name/", VER: "0.9", }, SD = [ { "@attributes": { FLAGS: "", HOST: "davidwalsh.name", TITLE: A }, LINKSIN: { "@attributes": { NUM: 1102 } }, SPEED: { "@attributes": { PCT: 51, TEXT: 1421 } }, TITLE: { "@attributes": { TEXT: "David Walsh Blog :: PHP, MySQL, CSS, Javascript, MooTools, and Everything Else", } }, }, { POPULARITY: { "@attributes": { TEXT: 7131, URL: "davidwalsh.name/" } }, RANK: { "@attributes": { DELTA: "-1648" } }, REACH: { "@attributes": { RANK = 5952 } } } ]}
