jstoxml

Convert JavaScript objects (and JSON) to XML (for RSS, Podcasts, etc.)

Everyone loves JSON, and more and more folks want to move that direction, but we still need things outputted in XML! Particularly for RSS feeds and Podcasts.

This is inspired by node-jsontoxml, which was found to be a bit too rough around the edges. jstoxml attempts to fix that by being more flexible.

Features

supports a variety of inputs: objects, arrays, strings,
tabbed output (optional)
custom filters (& -> &, etc) (optional)

Installation

npm install jstoxml

Version 0.2.1

IMPORTANT: empty text strings will now output as empty XML tags (NOT text content), which makes more sense and is more intuitive (see issue #3). To output text content, set the value to null instead (see Example 5 below).

For instance:

jstoxml.toXML({
  a: '1',
  foo: '',
  b: '2'
});
// Output: <a>1</a><foo></foo><b>2</b>

jstoxml.toXML({
  a: '1',
  foo: null,
  b: '2'
});
// Output: <a>1</a>foo<b>2</b>

Version 0.1.0

Added support for custom filters (for XML, UTF-8 entities, or whatever you need it for)
Changed to a single options object, passed as the second parameter. This will break older versions that use the XML header or indentation! They will need to be updated (see the examples below).

Examples

First you'll want to require jstoxml in your script, and assign the result to the namespace variable you want to use (in this case jstoxml):

var jstoxml = require('jstoxml');

Interface

jstoxml has a very simple interface: jstoxml.toXML(input, addHeader [Boolean], indent [String]);

input: accepts objects, arrays, strings, and even functions
addHeader (optional): pass in true to include the XML header (<?xml version="1.0" encoding="UTF-8"?>)
indent (optional): string which is used as an indent (i.e. ' ')

Example 1: Simple object

jstoxml.toXML({
  foo: 'bar',
  foo2: 'bar2'
});

Output:

<foo>bar</foo><foo2>bar2</foo2>

Example 2: Simple array

jstoxml.toXML([
  {foo: 'bar'},
  {foo2: 'bar2'}
]);

Output:

<foo>bar</foo><foo2>bar2</foo2>

Example 3: Duplicate tag names

Because we can't have duplicate keys in objects, we have to take advantage of arrays to get duplicate tag names:

jstoxml.toXML([
  {foo: 'bar'},
  {foo: 'bar2'}
]);

Output:

<foo>bar</foo><foo>bar2</foo>

Example 4: Attributes

jstoxml.toXML({
  _name: 'foo',
  _content: 'bar',
  _attrs: {
    a: 'b',
    c: 'd'
  }
});

Output:

<foo a="b" c="d">bar</foo>

Example 5: Tags mixed with text content

To output text content, set a key to null:

jstoxml.toXML({
  'text1': null,
  foo: 'bar',
  'text2': null
});

Output:

text1<foo>bar</foo>text2

Example 6: Nested tags (with indenting)

jstoxml.toXML({
  a: {
    foo: 'bar',
    foo2: 'bar2'
  }
}, {header: false, indent: '  '});

Output:

<a>
  <foo>bar</foo>
  <foo2>bar2</foo2>
</a>

Example 7: Nested tags with attributes (with indenting)

jstoxml.toXML({
  ooo: {
    _name: 'foo',
    _attrs: {
      a: 'b'
    },
    _content: {
      _name: 'bar',
      _attrs: {
        c: 'd'
      }
    }
  }
}, {header: false, indent: '  '});

Output:

<ooo>
  <foo a="b">
    <bar c="d"/>
  </foo>
</ooo>

Note that cases like this might be especially hard to read because of the deep nesting, so it's recommend you use something like this pattern instead, which breaks it up into more readable pieces:

var bar = {
  _name: 'bar',
  _attrs: {
    c: 'd'
  }
};

var foo = {
  _name: 'foo',
  _attrs: {
    a: 'b'
  },
  _content: bar
}

return jstoxml.toXML({
  ooo: foo
}, {header: false, indent: '  '})

Example 8: Functions

jstoxml.toXML({
  onePlusTwo: function(){
    return 1 + 2;
  },
  date: function(){
    return new Date();
  }
});

Output:

<onePlusTwo>3</onePlusTwo><date>Sat Jul 30 2011 17:49:52 GMT+0900 (JST)</date>

Example 9: RSS Feed

jstoxml.toXML({
  _name: 'rss',
  _attrs: {
    version: '2.0'
  },
  _content: {
    channel: [
      {title: 'RSS Example'},
      {description: 'Description'},
      {link: 'google.com'},
      {lastBuildDate: function(){
        return new Date();
      }},
      {pubDate: function(){
        return new Date();
      }},
      {language: 'en'},
      {item: {
        title: 'Item title',
        link: 'Item link',
        description: 'Item Description',
        pubDate: function(){
          return new Date();
        }
      }},
      {item: {
        title: 'Item2 title',
        link: 'Item2 link',
        description: 'Item2 Description',
        pubDate: function(){
          return new Date();
        }
      }}
    ]
  }
}, {header: true, indent: '  '});

Output:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  <channel>
    <title>RSS Example</title>
    <description>Description</description>
    <link>google.com</link>
