Webform submission results into XML datafile

Webform doesn't offer that as a built-in format. I *think* the API allows additional formats to be defined -- you'd have to check the API file. Another thought would be to see if there is an XML output module for views and use the webform views integration.

Good luck.

Hi,

Here is a starting point to a solution to this problem.

I used the hook_webform_submission_insert() to create an XML file for each submission.

/**
 * Implements hook_webform_submission_insert
 * @param $node
 * @param $submission
 */
function hook_webform_submission_insert($node, $submission){

  $data = $submission->data;
  $components = $node->webform['components'];
  $array = array();
//Recreate an array with form_key (system name of a component) as key, and value
  foreach($components as $key => $component){
    $array[$component['form_key']] = $data[$key]['value'][0];
  }

  $xmlstr = format_xml_elements($array);

   //Just setting the filename with the webform ID and the submission ID
  $filename = 'webform-'.$node->nid.'-submission-'.$submission->sid.'.xml';

  //An example for storing the file, but it's not a good idea to store it in public folder.
  file_save_data($xmlstr, 'public://submissions/'.$filename);

}

You also need to set an XML header : $xmlstr = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>
";
