It does not parse the following elements:
* CDATA sections
* Processing instructions
* XML declarations
* Entity declarations
* Comments
## Installation
npm install xml2json
## Usage
```javascript
var parser = require('xml2json');
var xml = "bar";
var json = parser.toJson(xml); //returns an string containing the json structure by default
console.log(json);
```
* if you want to get the Javascript object then you might want to invoke parser.toJson(xml, {object: true});
* if you want a reversible json to xml then you should use parser.toJson(xml, {reversible: true});
