XmlSimple Puppet Functions

These Puppet functions will convert a hash into an XML string that can be saved as the contents of a file. There is also a function that will accept an argument of a path to an XML document and return a native Hash. Hopefully these are useful to some people out there. Check out the tests/ directory for Puppet manifests demonstrating their usage:

NOTE - REQUIRES 'xml-simple' GEM!

Do note, you need to install the 'xml-simple' gem with the following command:

gem install xml-simple

Converting an XML document to a Hash

$xml = '/tmp/sample.xml'
$hash_data = xml_to_hash($xml)

Converting a Hash to an XML document

$hash = {
  'logdir'        => '/var/log/foo/',
    'debugfile'     => '/tmp/foo.debug',
    'server'        => {
      'sahara'        => {
        'osversion'     => '2.6',
        'osname'        => 'solaris',
        'address'       => [ '10.0.0.101', '10.0.1.101' ]
      },
      'gobi'          => {
        'osversion'     => '6.5',
        'osname'        => 'irix',
        'address'       => [ '10.0.0.102' ]
      },
      'kalahari'      => {
        'osversion'     => '2.0.34',
        'osname'        => 'linux',
        'address'       => [ '10.0.0.103', '10.0.1.103' ]
      }
    }
}

$xml_data = hash_to_xml($hash)

file { '/tmp/sample.xml':
  ensure  => file,
  content => $xml_data
}

The resultant output XML file:

<opt logdir="/var/log/foo/" debugfile="/tmp/foo.debug">
  <server>
    <sahara osversion="2.6" osname="solaris">
      <address>10.0.0.101</address>
      <address>10.0.1.101</address>
    </sahara>
    <gobi osversion="6.5" osname="irix">
      <address>10.0.0.102</address>
    </gobi>
    <kalahari osversion="2.0.34" osname="linux">
      <address>10.0.0.103</address>
      <address>10.0.1.103</address>
    </kalahari>
  </server>
</opt>
You can’t perform that action at this time.
