function juicebox_render_gallery_xml in Juicebox HTML5 Responsive Image Galleries 7

Render the final XML for a Juicebox gallery.

This function is a bit like drupal_render() in that it takes an associative array as input and returns final markup. Actaully, this function's $data input could probably be made to work with drupal_render(), but as we are producing structured XML here (and not HTML), using a custom function instead seems more prudent and flexible.

Parameters

array $data: An associative array containing all the content variables that will be used in the Juicebox XML.

Return value

string Fully renderd XML data for a Juicebox gallery.

Code

function juicebox_render_gallery_xml($data) {

  // much more flexible (CDATA is supported, etc.).

  $juicebox = $dom
