100分求助如何用javascript语言把XML转换成JSON

给你个例子，很详细<html>
<body>
<script type="text/javascript">
var xml =
'<admin>\n' +
'    <Attribute id = "Sort">0</Attribute>\n' +
'    <Attribute id = "SortView">0</Attribute>\n' +
'    <Attribute id = "TCView">0</Attribute>\n' +
'    <Attribute id = "Deep">4</Attribute>\n' +
'    <Attribute id = "TCode"></Attribute>\n' +
'    <Nodes>\n' +
'        <_1>\n' +
'            <_1 id="Text">1111</_1>\n' +
'            <_1 id="ID">A-2018</_1>\n' +
'            <_1 id="Deep">0</_1>\n' +

    }

result += '\t}\n};';
alert(result);
</script>
</body>
</html>你在此基础上改改就行！！

输出的结果是:var Cont = {
    "Nodes": [
        {
            "Text": "1111"
            ,"ID": "A-2018"
            ,"Deep": "0"
            ,"Sort": "0"
            ,"ParentID": "null"
            ,"Taxis": "0"
            ,"Display": ""
            ,"Class": ""
            ,"Type": "0"
            ,"TCode": ""
        }
        ,{
            "Text": "2222"
            ,"ID": "A-2018"
            ,"Deep": "0"
            ,"Sort": "0"
            ,"ParentID": "null"
            ,"Taxis": "0"
            ,"Display": ""
            ,"Class": ""
            ,"Type": "0"
            ,"TCode": ""
        }
    ]
    ,"Attribute":{
        "Sort": "0"
        ,"SortView": "0"
        ,"TCView": "0"
        ,"Deep": "4"
        ,"TCode": ""
    }
};
