這篇文章主要介紹了JavaScript將XML轉成JSON的方法,實例分析了javascript操作XML文件及格式轉化的技巧,具有一定參考借鑒價值,需要的朋友可以參考下

本文實例講述了JavaScript將XML轉成JSON的方法。分享給大家供大家參考。具體方法如下：

1. JavaScript代碼如下：

復制代碼代碼如下:

		// 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代碼：

復制代碼代碼如下:

		<ALEXA VER="0.9" URL="davidwalsh.name/" HOME="0" AID="=">
		    <SD style="border-left-color: rgb(0, 153, 204); border-left-width: 1px; border-left-style: solid; padding: 0px 3px; margin: 3px auto 0px; width: 640px; background-color: rgb(242, 246, 251); clear: both; border-top-color: rgb(0, 153, 204); border-top-width: 1px; border-top-style: solid; border-right-color: rgb(0, 153, 204); border-right-width: 1px; border-right-style: solid;">		復制代碼代碼如下:

		{
		  "@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
		        }
		      }
		    }
		  ]
		}
