Jsonix

* Jsonix (JSON interfaces for XML) is a JavaScript library which allows you to convert between XML and JSON structures.
* With Jsonix you can parse XML into JSON (this process is called _unmarshalling_) or serialize JSON in XML form (this is called _marshalling_).
* These conversions are based on declarative XML/JSON mappings which can be written manually or generated from an XML Schema.

Jsonix advantages:

* Strongly structured
* Type-safe
* Bidirectional
* (Optionally) XML Schema-driven

Example

Here's a working example for the purchase order schema (try it online in JSFiddle).

$3

``
java -jar node_modules/jsonix/lib/jsonix-schema-compiler-full.jar
-d mappings -p PO purchaseorder.xsd
`

Generates mappings for the purchaseorder.xsd schema in the mappings\PO.js; mappings will be placed in the variable PO.

$3

`javascript
// Include or require PO.js so that PO variable is available
// For instance, in node.js:
var PO = require('./mappings/PO').PO;

// First we construct a Jsonix context - a factory for unmarshaller (parser)
// and marshaller (serializer)
var context = new Jsonix.Context([PO]);

// Then we create a unmarshaller
var unmarshaller = context.createUnmarshaller();

// Unmarshal an object from the XML retrieved from the URL
unmarshaller.unmarshalURL('po.xml',
// This callback function will be provided
// with the result of the unmarshalling
function (unmarshalled) {
// Alice Smith
console.log(unmarshalled.value.shipTo.name);
// Baby Monitor
console.log(unmarshalled.value.items.item[1].productName);
});
`

You can also unmarshalString, unmarshalDocument and (under node.js) unmarshalFile.

$3

`javascript
// Create a marshaller
var marshaller = context.createMarshaller();

// Marshal a JavaScript Object as XML (DOM Document)
var doc = marshaller.marshalDocument({
name: {
localPart: "purchaseOrder"
},
value: {
orderDate: { year: 1999, month: 10, day: 20 },
shipTo: {
country: "US",
name: "Alice Smith",
street: "123 Maple Street",
city: "Mill Valley",
state: "CA",
zip: 90952
},
billTo: { / ... / },
comment: 'Hurry, my lawn is going wild!',
items: { / ... / }
}
});
`

You can also marshalString`.

Jsonix Features

* Runs in almost any modern browser
* Runs in Node.js
* Runs with CommonJS modules, AMD modules as well as vanilla (globals, without any module loader)
* Bidirectional (XML -> JS as well as JS -> XML)
Implements marshalling* (serializing the JavaScript object into XML)
* Supports string data and DOM nodes as result
Implements unmarshalling* (parsing a JavaScript object from XML)
* Supports string data, DOM nodes, URLs or files (with Node.js) as source
* Driven by declarative XML/JS mappings which control how JavaScript object is converted into XML or vice versa
* Mappings can be automatically generated based on the XML Schema
* Strongly-structured - XML/object mappings describe structures of JavaScript objects
* Strongly-typed - Conversion between string content on XML side and values on the JavaScript side is controlled by declared property types
* Provides extensible type system
* Supports most XML Schema simple types (inlcuding QNames)
* Supports enumerations, list and union simple types
* Allows adding own simple types
* Supports complex types consisting of several properties
* Supports deriving complex types by extension
* Provides advanced property system
* Value, attribute, element, element reference properties for string processing of XML content
* Any attribute, any element properties for "lax" processing for XML content
