 node-xml2js

+Usage
+=====
 
-    var fs = require('fs'),
-        xml2js = require('xml2js');
+This will have to do, unless you're looking for some fancy extensive
+documentation. If you're looking for every single option and usage, see the

+Simple as pie usage
+-------------------
+
+The simplest way to use it, is to use the optional callback interface added in
+0.1.11. That's right, if you have been using xml-simple or a home-grown
+wrapper, this is for you:
+
+```javascript
+var fs = require('fs'),
+    xml2js = require('xml2js');
+
+var parser = new xml2js.Parser();
+fs.readFile(__dirname + '/foo.xml', function(err, data) {
+    parser.parseString(data, function (err, result) {
         console.dir(result);
-        console.log('Done.');
+        console.log('Done');
     });
-    fs.readFile(__dirname + '/foo.xml', function(err, data) {
-        parser.parseString(data);
-    });
+});
+```
 
+Look ma, no event listeners! Alternatively you can still use the traditional
+`addListener` variant:
+
+```javascript
+var fs = require('fs'),
+    xml2js = require('xml2js');
+
+var parser = new xml2js.Parser();
+parser.addListener('end', function(result) {
+    console.dir(result);
+    console.log('Done.');
+});
+fs.readFile(__dirname + '/foo.xml', function(err, data) {
+    parser.parseString(data);
+});
+```
+
+You can also use xml2js from
+[CoffeeScript](http://jashkenas.github.com/coffee-script/), further reducing
+the clutter:
+
+```coffeescript
+fs = require 'fs',
+xml2js = require 'xml2js'
+
+parser = new xml2js.Parser()
+fs.readFile __dirname + '/foo.xml', (err, data) ->
+  parser.parseString data, (err, result) ->
+    console.dir result
+    console.log 'Done.'
+```
+
+So you wanna some JSON?
+-----------------------
+
+Just wrap the `result` object in a call to `JSON.stringify` like this
+`JSON.strintify(result)`. You get a string containing the JSON representation
+of the parsed object that you can feed to JSON-hungry consumers.
+
+Displaying results
+------------------
+
+You might wonder why, using `console.dir` or `console.log` the output at some
+level is only `[Object]`. Don't worry, this is not because xml2js got lazy.
+That's because Node uses `util.inspect` to convert the object into strings and
+that function stops after `depth=2` which is a bit low for most XML.
+
+To display the whole deal, you can use `console.log(util.inspect(result, false,
+null))`, which displays the whole result.
+
+So much for that, but what if you use
+[eyes](https://github.com/cloudhead/eyes.js) for nice colored output and it
+truncates the output with `…`? Don't fear, there's also a solution for that,
+you just need to increase the `maxLength` limit by creating a custom inspector
+`var inspect = require('eyes').inspector({maxLength: false})` and then you can
+easily `inspect(result)`.
