I have a single SQL table containing all the attributes as columns. I need to parse the data and put all the data into one single mySQL table, also the repeated attributes should be ignored. The XML format cannot be changed. I have wriiten a node.js app ad using xml2j I can parse the string but I don't know how to go ahead.

Here is my node.js code,

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var qs = require('querystring');
var redis = require('redis').createClient();
var parseString = require('xml2js').parseString;
var count = 0;

app.get('/adminm', function (req, res) {
    res.sendfile('adminmovies.html');
});

app.get('/admine', function (req, res) {
    res.sendfile('adminevents.html');
});

app.post('/', function (req, res) {
    count = count + 1;
    var body = "";
    req.on('data', function (data) {
        body += data;
    });
    req.on('end', function () {
        //console.log(body);
        var xml = body;
        var parsed = "";
        parseString(xml, function (err, result) {
            console.log(JSON.stringify(result));
            redis.lpush("events", JSON.stringify(result));

        });

        io.emit('count1', count);
    });
});
http.listen(3000, function () {
    console.log('listening on *:3000');
});

Now I need the data in this format,

{name: 'XYZ', age: '21', ....}

How do I proceed?

I think part of the problem is that the XML you have is using attributes for everything. It might be somewhat easier if it used elements. Take a look at my https://github.com/imbroglioj/xml-to-es which allows you to specify in a property file how you want your resultant JSON object massaged by promoting child elements or attributes to top-level, etc. It would be easy to extend the property file and the collapsing function to erase fields or rename them.
