is there any way to make the webform components labels translatable?

Question

Just wondering how to make the webform components labels translatable. I found this post with a link to a sandbox project but I don't where to download the module: Make Webform multilingual (i18n) aware through contributed modules

I also find this function to just make what I need but it doesn't work, maybe with a few change it will work: Source: work around

function module_name_form_webform_client_form_xx_alter(&$form, &$form_state) { 
  foreach (element_children($form['submitted']) as $element) { 
    // Pass each webform component title through the t() function. 
    $form['submitted'][$element]['#title'] = t($form['submitted'][$element]['#title']); 
  } 
} 

The function provided by @lenni does the job but I get these error messages.

Warning: strlen() expects parameter 1 to be string, array given en drupal_validate_utf8() (línea 1600 de/Applications/MAMP/htdocs/tonisacristan.com/includes/bootstrap.inc).

The source of the problem is a Markup component. This function is working fine.

function webform_extras_node_view($node, $view_mode, $langcode) {
  if($node->type == 'webform' && $view_mode == 'full') {
    // translate the webform component labels
    foreach(element_children($node->content['webform']['#form']['submitted']) as $key){
      //to skip Markup components
      if($key != 'my_markup_component'){
        $node->content['webform']['#form']['submitted'][$key]['#title'] = t($node->content['webform']['#form']['submitted'][$key]['#title']);
      }
    }
  }
}

Similar (a litte bit more generic) solution but still not a clean one:

function mymodule_node_view($node, $view_mode, $langcode) {
  if($node->type == 'webform' && $view_mode == 'full') {
    // translate the webform component labels
    foreach(element_children($node->content['webform']['#form']['submitted']) as $key){
      $node->content['webform']['#form']['submitted'][$key]['#title'] = t($node->content['webform']['#form']['submitted'][$key]['#title']);
    }
  }
}

And if you actually want to translate your markup fields as well, which is often the case:

function mymodule_node_view($node, $view_mode, $langcode) {  

  if ($node->type == 'webform') {
    // translate the webform component labels
    foreach(element_children($node->content['webform']['#form']['submitted']) as $key){
      if($key != 'your_markup_component' && $key != 'your_markup_component_2'){
        $node->content['webform']['#form']['submitted'][$key]['#title'] = t($node->content['webform']['#form']['submitted'][$key]['#title']);
      }
      else {
        $node->content['webform']['#form']['submitted'][$key]['#value'] = t($node->content['webform']['#form']['submitted'][$key]['#value']);
      }
    }
  }
}
