## Dependencies

xmlson uses ltx which uses libexpat - a super fast native XML parser. You may need to install it if your OS does not have it installed already.

```
$ sudo apt-get install libexpat1 libexpat1-dev
```

## Usage

### Synchronous

```coffee-script
xmlson = require 'xmlson'

myObject = xmlson.toJSON '<cool><whatever name="ya"/></cool>'
# myObject = {cool:{whatever:[{"@name":"ya"}]}

myString = xmlson.toXML {cool:{whatever:[{"@name":"ya"}]}}
# myString = <cool><whatever name="ya"/></cool>
```

### Asynchronous

```coffee-script
xmlson = require 'xmlson'

xmlson.toJSON '<cool><whatever name="ya"/></cool>', (err, myObject) ->
  # myObject = {cool:{whatever:[{"@name":"ya"}]}

xmlson.toXML {cool:{whatever:[{"@name":"ya"}]}}, (err, myString) ->
  # myString = <cool><whatever name="ya"/></cool>
```

## Benchmarks

These were done on a laptop with an i7 - you will probably get much better results on an actual server.

Summary:

A complex JSON object can be turned into an XML string in 0.052ms (avg)

A complex XML string can be turned into a JSON object in 0.015ms (avg)
