Simple SAX-based XML2JSON Parser.

It does not parse the following elements:

  • CDATA sections (*)
  • Processing instructions
  • XML declarations
  • Entity declarations
  • Comments

Installation

$ npm install xml2json

Usage

var parser = require('xml2json');

var xml = "<foo>bar</foo>";
var json = parser.toJson(xml); //returns a string containing the JSON structure by default
console.log(json);

API

parser.toJson(xml, options);
parser.toXml(json, options);

Options object

Default values:

var options = {
    object: false,
    reversible: false,
    coerce: true,
    sanitize: true,
    trim: true,
    arrayNotation: false
};
  • object: Returns a Javascript object instead of a JSON string
  • reversible: Makes the JSON reversible to XML (*)
  • coerce: Makes type coercion. i.e.: numbers and booleans present in attributes and element values are converted from string to its correspondent data types.
  • trim: Removes leading and trailing whitespaces as well as line terminators in element values.
  • arrayNotation: XML child nodes are always treated as arrays
  • sanitize: Sanitizes the following characters present in element values:
var chars =  {
    '<': '&lt;',
    '>': '&gt;',
    '(': '&#40;',
    ')': '&#41;',
    '#': '&#35;',
    '&': '&amp;',
    '"': '&quot;',
    "'": '&apos;'
};

(*) xml2json tranforms CDATA content to JSON, but it doesn't generate a reversible structure.
