XMLer

XMLer is a simple package for creating XML elements. It allows elements to be created as JavaScript objects, adding attributes and child elements to the element, and provides a way to easily convert the element into an XML string.

Getting Started

Installation

$ npm install node-xmler

Usage

var xmler = require('node-xmler');

var cat = new xmler.Element('cat');
var name = new xmler.Element('name', 'Mr. Meowgi');
var breed = new xmler.Element('breed', 'Munchkin');

breed.addAttribute({
  key: 'purebred',
  value: 'true'
});

cat.addElement(name);
cat.addElement(breed);

var xml = cat.getXML();
console.log(xml);

The output of the console.log(xml) will be:

<cat>
  <name>Mr. Meowgi</name>
  <breed purebred="true">Munchkin</breed>
</cat>

In Depth

Creating an Element

An element can be created by specifying its name and optionally its body content in the arguments.

var cat = new xmler.Element(name, [body]); // <name>body</name>

Note: The body content should be plain text with any required inline XML

Adding Attributes

Attributes are objects that have key and value fields and can be added to an element's attributes as a single object or as part of an array of attributes.

addAttribute(attribute)

var cat = new xmler.Element('cat');
var attr = { key: 'color', value: 'grey' };
cat.addAttribute(attr); // <cat color="grey"...

addAttributes(attributes)

var cat = new xmler.Element('cat');
var attr = [
  { key: 'color', value: 'grey' },
  { key: 'cute', value: 'true' }
];

cat.addAttributes(attr); // <cat color="grey" cute="true"...

Adding Child Elements

Child elements can be added in similar fashion to attributes, either as a single object or as an array of children.

addElement(element)

var cat = new xmler.Element('cat');
var name = new xmler.Element('name', 'Mr. Meowgi');
cat.addElement(name); // <cat><name>Mr. Meowgi</name></cat>

addElements(elements)

var cat = new xmler.Element('cat');
var children = [
  new xmler.Element('name', 'Mr. Meowgi'),
  new xmler.Element('breed', 'Munchkin')
];

cat.addElements(children); // <cat><name>...</name><breed>...</breed></cat>

Converting to XML

You can convert an element along with any children to an XML string using the getXML() function.

getXML()

var cat = new xmler.Element('cat');
var xml = cat.getXML(); // Your element as an XML string

Running Tests

Tests are written using mocha and chai and can be run through gulp.

$ npm install -g gulp mocha
