在Javascript中解析内存中的xml字符串并转换为JSON
由于一些不可抗力因素导致我需要将一个从js函数中返回的字符串变量（内容为xml）转换为IXMLDOMDocument2，进而转换为json，需要能跨浏览器，网上搜了很多种方法，加载xml的时候都必须用ajax加载外部文件中的xml，浪了半天，终于结果了：
==========
//解析xml字符串变量为IXMLDOMDocument2 function parseXML(data){ var xml,tmp; if ( window.DOMParser ) { // Standard tmp = new DOMParser(); xml = tmp.parseFromString( data , "text/xml" ); } else { // IE xml = new ActiveXObject( "Microsoft.XMLDOM" ); xml.async = "false"; xml.loadXML( data ); } tmp = xml.documentElement; if ( ! tmp || ! tmp.nodeName || tmp.nodeName === "parsererror" ) { return null; } return xml; }?将IXMLDOMDocument2转换为JSON，参数为IXMLDOMDocument2对象
function toJson (obj){if (this==null) return null;var retObj = new Object;buildObjectNode(retObj,/*jQuery*/obj);return retObj;function buildObjectNode(cycleOBJ,/*Element*/elNode){/*NamedNodeMap*/var nodeAttr=elNode.attributes;if(nodeAttr != null){if (nodeAttr.length&&cycleOBJ==null) cycleOBJ=new Object; for(var i=0;i<nodeAttr.length;i++){cycleOBJ[nodeAttr[i].name]=nodeAttr[i].value;}}var nodeText="text";if (elNode.text==null) nodeText="textContent";/*NodeList*/var nodeChilds=elNode.childNodes;if(nodeChilds!=null){if (nodeChilds.length&&cycleOBJ==null) cycleOBJ=new Object; for(var i=0;i<nodeChilds.length;i++){if (nodeChilds[i].tagName!=null){if (nodeChilds[i].childNodes[0]!=null&&nodeChilds[i].childNodes.length<=1&&(nodeChilds[i].childNodes[0].nodeType==3||nodeChilds[i].childNodes[0].nodeType==4)){if (cycleOBJ[nodeChilds[i].tagName]==null){cycleOBJ[nodeChilds[i].tagName]=nodeChilds[i][nodeText];}else{if (typeof(cycleOBJ[nodeChilds[i].tagName])=="object"&&cycleOBJ[nodeChilds[i].tagName].length){cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length]=nodeChilds[i][nodeText];}else{cycleOBJ[nodeChilds[i].tagName]=[cycleOBJ[nodeChilds[i].tagName]];cycleOBJ[nodeChilds[i].tagName][1]=nodeChilds[i][nodeText];}}}else{if (nodeChilds[i].childNodes.length){if (cycleOBJ[nodeChilds[i].tagName]==null){cycleOBJ[nodeChilds[i].tagName]=new Object;buildObjectNode(cycleOBJ[nodeChilds[i].tagName],nodeChilds[i]);}else{if (cycleOBJ[nodeChilds[i].tagName].length){cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length]=new Object;buildObjectNode(cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length-1],nodeChilds[i]);}else{cycleOBJ[nodeChilds[i].tagName]=[cycleOBJ[nodeChilds[i].tagName]];cycleOBJ[nodeChilds[i].tagName][1]=new Object;buildObjectNode(cycleOBJ[nodeChilds[i].tagName][1],nodeChilds[i]);}}}else{cycleOBJ[nodeChilds[i].tagName]=nodeChilds[i][nodeText];}}}}}}}?
