Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (xml) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

xml

Fast and simple Javascript-based XML generator/builder for Node projects.

Install

$ npm install xml

API

`xml(xmlObject, options)`

Returns a XML string.

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.

xml({a: 1}) === '<a>1</a>'
xml({nested: [{ keys: [{ fun: 'hi' }]}]}) === '<nested><keys><fun>hi</fun></keys></nested>'

There are two special keys:

_attr

Set attributes using a hash of key/value pairs.

xml({a: [{ _attr: { attributes: 'are fun', too: '!' }}, 1]}) === '<a attributes="are fun" too="!">1</a>'

_cdata

Value of _cdata is wrapped in xml ![CDATA[]] so the data does not need to be escaped.

xml({a: { _cdata: "i'm not escaped: <xml>!"}}) === '<a><![CDATA[i\'m not escaped: <xml>!]]></a>'

Mixed together:

xml({a: { _attr: { attr:'hi'}, _cdata: "I'm not escaped" }}) === '<a attr="hi"><![CDATA[I\'m not escaped]]></a>'

`options`

indent optional string What to use as a tab. Defaults to no tabs (compressed). For example you can use '\t' for tab character, or ' ' for two-space tabs.

stream Return the result as a stream.

Stream Example

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: <toys decade="80s" locale="US">
data:     <toy>Transformers</toy>
data:     <toy>GI Joe</toy>
data:     <toy>
            <name>He-man</name>
          </toy>
data: </toys>
*/

Declaration optional Add default xml declaration as first node.

options are:

encoding: 'value'
standalone: 'value'

Declaration Example

xml([ { a: 'test' }], { declaration: true })
//result: '<?xml version="1.0" encoding="UTF-8"?><a>test</a>'

xml([ { a: 'test' }], { declaration: { standalone: 'yes', encoding: 'UTF-16' }})
//result: '<?xml version="1.0" encoding="UTF-16" standalone="yes"?><a>test</a>'

Examples

Simple Example

var example1 = [ { url: 'http://www.google.com/search?aq=f&sourceid=chrome&ie=UTF-8&q=opower' } ];
console.log(XML(example1));
//<url>http://www.google.com/search?aq=f&amp;sourceid=chrome&amp;ie=UTF-8&amp;q=opower</url>

Example with attributes

var example2 = [ { url: { _attr: { hostname: 'www.google.com', path: '/search?aq=f&sourceid=chrome&ie=UTF-8&q=opower' }  } } ];
console.log(XML(example2));
//result: <url hostname="www.google.com" path="/search?aq=f&amp;sourceid=chrome&amp;ie=UTF-8&amp;q=opower"/>

Example with array of same-named elements and nice formatting

var example3 = [ { toys: [ { toy: 'Transformers' } , { toy: 'GI Joe' }, { toy: 'He-man' } ] } ];
console.log(XML(example3));
//result: <toys><toy>Transformers</toy><toy>GI Joe</toy><toy>He-man</toy></toys>
console.log(XML(example3, true));
/*
result:
<toys>
    <toy>Transformers</toy>
    <toy>GI Joe</toy>
    <toy>He-man</toy>
</toys>
*/

More complex example

var example4 = [ { toys: [ { _attr: { decade: '80s', locale: 'US'} }, { toy: 'Transformers' } , { toy: 'GI Joe' }, { toy: 'He-man' } ] } ];
console.log(XML(example4, true));
/*
result:
<toys decade="80s" locale="US">
    <toy>Transformers</toy>
    <toy>GI Joe</toy>
    <toy>He-man</toy>
</toys>
*/

Even more complex example

var example5 = [ { toys: [ { _attr: { decade: '80s', locale: 'US'} }, { toy: 'Transformers' } , { toy: [ { _attr: { knowing: 'half the battle' } }, 'GI Joe'] }, { toy: [ { name: 'He-man' }, { description: { _cdata: '<strong>Master of the Universe!</strong>'} } ] } ] } ];
console.log(XML(example5, true));
/*
result:
<toys decade="80s" locale="US">
    <toy>Transformers</toy>
    <toy knowing="half the battle">
        GI Joe
    </toy>
    <toy>
        <name>He-man</name>
        <description><![CDATA[<strong>Master of the Universe!</strong>]]></description>
    </toy>
</toys>
