Fast and simple isomorphic xml generator. Supports attributes, CDATA, etc. Includes tests and examples.
npm install @kyleshockey/xmlThis is a fork of xml that supports usage in browsers, without the need for a module loader/bundler that supports shimming built-in Node.js modules.
This is made possible by listing stream as a dependency in the package manifest. Since Node.js prioritizes its own built-in modules over third-party modules of the same name, Node.js continues to use the built-in implementation, while a browser context also gets the stream module that it needs.

> Fast and simple Javascript-based XML generator/builder for Node projects.
npm install @kyleshockey/xml
Returns a XML string.
``js`
var xml = require('xml');
var xmlString = xml(xmlObject, options);
#### xmlObject
xmlObject is a normal JavaScript Object/JSON object that defines the data for the XML string.
Keys will become tag names.
Values can be an array of xmlObjects or a value such as a string or number.
`js`
xml({a: 1}) === '1'
xml({nested: [{ keys: [{ fun: 'hi' }]}]}) === '
There are two special keys:
_attr
Set attributes using a hash of key/value pairs.
`js``
xml({a: [{ _attr: { attributes: 'are fun', too: '!' }}, 1]}) === '1'
Value of _cdata is wrapped in xml ![CDATA[]] so the data does not need to be escaped.
`js`
xml({a: { _cdata: "i'm not escaped:
Mixed together:
`js`
xml({a: { _attr: { attr:'hi'}, _cdata: "I'm not escaped" }}) === ''
#### options
indent _optional_ string What to use as a tab. Defaults to no tabs (compressed).'\t'
For example you can use for tab character, or ' ' for two-space tabs.
stream Return the result as a stream.
Stream Example
`js
var elem = xml.element({ _attr: { decade: '80s', locale: 'US'} });
var stream = xml({ toys: elem }, { stream: true });
stream.on('data', function (chunk) {console.log("data:", chunk)});
elem.push({ toy: 'Transformers' });
elem.push({ toy: 'GI Joe' });
elem.push({ toy: [{name:'He-man'}] });
elem.close();
/*
result:
data:
data:
data:
data:
data:
*/
`
Declaration _optional_ Add default xml declaration as first node.
_options_ are:
* encoding: 'value'
* standalone: 'value'
Declaration Example
`js
xml([ { a: 'test' }], { declaration: true })
//result: 'test'
xml([ { a: 'test' }], { declaration: { standalone: 'yes', encoding: 'UTF-16' }})
//result: 'test'
`
Simple Example
`js`
var example1 = [ { url: 'http://www.google.com/search?aq=f&sourceid=chrome&ie=UTF-8&q=opower' } ];
console.log(XML(example1));
//
Example with attributes
`js`
var example2 = [ { url: { _attr: { hostname: 'www.google.com', path: '/search?aq=f&sourceid=chrome&ie=UTF-8&q=opower' } } } ];
console.log(XML(example2));
//result:
Example with array of same-named elements and nice formatting
`js`
var example3 = [ { toys: [ { toy: 'Transformers' } , { toy: 'GI Joe' }, { toy: 'He-man' } ] } ];
console.log(XML(example3));
//result:
console.log(XML(example3, true));
/*
result:
*/
More complex example
`js`
var example4 = [ { toys: [ { _attr: { decade: '80s', locale: 'US'} }, { toy: 'Transformers' } , { toy: 'GI Joe' }, { toy: 'He-man' } ] } ];
console.log(XML(example4, true));
/*
result:
*/
Even more complex example
`js`
var example5 = [ { toys: [ { _attr: { decade: '80s', locale: 'US'} }, { toy: 'Transformers' } , { toy: [ { _attr: { knowing: 'half the battle' } }, 'GI Joe'] }, { toy: [ { name: 'He-man' }, { description: { _cdata: 'Master of the Universe!'} } ] } ] } ];
console.log(XML(example5, true));
/*
result:
GI Joe
*/
