Finding XML elements by type and ID in node.js

Question

I'm kinda new to node.js and really new to using it with XML. I can't figure out how to find a specific element in a XML document based on the element's ID and type.

Basically, what I'm trying to do is handle requests with Express and then using a value from a query string in the request, search for an element in a XML document and send the contents of that element back as the response.

Here's some of my code:

var express = require('express'),
    xmlDoc = require('document.xml'),
    app = express();

app.get('/', function(req, res){
    var id = req.query.id;
    /* Here's where I want to get the element from xmlDoc based on id and element type*/
    res.send(/* Send the contents of the element */)
});

app.listen(3000);

Thanks in advance!

xmldom provides an implementation of the DOM Api for node.js

var DOMParser = new (require('xmldom')).DOMParser;
var document = DOMParser.parseFromString(xmlString);

var nodeById = document.getElementById('someId');
var nodesByName = document.getElementsByTagName('someName');

If you need more flexibility check out xpath.

You need to use some XML parser like libxmljs, xmldoc or node-xml2js which is a XML to JS object converter.
