@titanium/xml2json

Configurable, lightweight XML to JSON converter for Titanium native mobile apps. Based on https://github.com/metatribal/xmlToJSON by metatribal

📝 Description

Features

no external dependencies
small (~3kb minified)
simple parsing. pass either a string or xml node and get back a javascript object ( use JSON.stringify(obj) to get the string representation )
supports attributes, text, cdata, namespaces, default namespaces, attributes with namespaces... you get the idea
lots of rendering of options
consistent, predictable output
browser support - it works on IE 9+, and nearly every version of Chrome, Safari, and Firefox as well as iOS, Android, and Blackberry. (xmlToJSON will work for IE 7/8 as well if you set the xmlns option to false)

🚀 Getting Started

Install using npm:

npm install @titanium/xml2json

Usage

const xml2json = require('@titanium/xml2json');
const testString = '<xml><a>It Works!</a></xml>';  	// get some xml (string or document/node)
const result = xml2json.parseString(testString);	// parse

The (prettified) result of the above code is

{
   "xml": {
       "a": [
           {
               "text": "It Works!"
           }
       ]
   }
}

Options

// These are the option defaults
var options = { 
	mergeCDATA: true,	// extract cdata and merge with text nodes
	grokAttr: true,		// convert truthy attributes to boolean, etc
	grokText: true,		// convert truthy text/attr to boolean, etc
	normalize: true,	// collapse multiple spaces to single space
	xmlns: true, 		// include namespaces as attributes in output
	namespaceKey: '_ns', 	// tag name for namespace objects
	textKey: '_text', 	// tag name for text nodes
	valueKey: '_value', 	// tag name for attribute values
	attrKey: '_attr', 	// tag for attr groups
	cdataKey: '_cdata',	// tag for cdata nodes (ignored if mergeCDATA is true)
	attrsAsObject: true, 	// if false, key is used as prefix to name, set prefix to '' to merge children and attrs.
	stripAttrPrefix: true, 	// remove namespace prefixes from attributes
	stripElemPrefix: true, 	// for elements of same name in diff namespaces, you can enable namespaces and access the nskey property
	childrenAsArray: true 	// force children into arrays
};	

// you can change the defaults by passing the parser an options object of your own
var myOptions = {
	mergeCDATA: false,
	xmlns: false,
	attrsAsObject: false
}

result = xml2json.parseString(xmlString, myOptions);

A more complicated example (with xmlns: true)

<?xml version="1.0" encoding="UTF-8"?>
<xml xmlns="http://default.namespace.uri">
    <a>
        <b id="1">one</b>
        <b id="2"><![CDATA[some <cdata>]]>two</b>
        <ns:c xmlns:ns="http://another.namespace" ns:id="3">three</ns:c>
    </a>
</xml>

results in

{
        "xml": [{
                "attr": {
                        "xmlns": {
                                "value": "http://default.namespace.uri"
                        }
                },
                "a": [{
                        "b": [{
                                "attr": {
                                        "id": {
                                                "value": 1
                                        }
                                },
                                "text": "one"
                        }, {
                                "attr": {
                                        "id": {
                                                "value": 2
                                        }
                                },
                                "text": "some <cdata>two"
                        }],
                        "c": [{
                                "attr": {
                                        "xmlns:ns": {
                                                "value": "http://another.namespace"
                                        },
                                        "id": {
                                                "value": 3
                                        }
                                },
                                "text": "three"
                        }]
                }]
        }]
