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]; } } } } } } }
