function commerce_simplexml_add_children in Commerce Core 7

Adds child elements to a SimpleXML element using the data provided.

Parameters

$simplexml_element: The SimpleXML element that will be populated with children from the child data array. This should already be initialized with its container element.

$child_data: The array of data. It can be of any depth, but it only provides support for child elements and their values - not element attributes. If an element can have multiple child elements with the same name, you cannot depend on a simple associative array because of key collision. You must instead include each child element as a value array in a numerically indexed array.

Code

function commerce_simplexml_add_children(&$simplexml_element, $child_data) {

  // Loop over all the child data...
  foreach ($child_data as $key => $value) {

    // If the current child is itself a container...
    if (is_array($value)) {

      // If it has a non-numeric key...
      if (!is_numeric($key)) {

        // Add a child element to the current element with the key as the name.
        $child_element = $simplexml_element
          ->addChild("{$key}");

        // Add the value of this element to the child element.
        commerce_simplexml_add_children($child_element, $value);
      }
      else {

        // Otherwise assume we have multiple child elements of the same name and
        // pass through to add the child data from the current value array to
        // current element.
        commerce_simplexml_add_children($simplexml_element, $value);
      }
    }
    else {

      // Otherwise add the child element with its simple value.
      $simplexml_element
        ->addChild("{$key}", htmlspecialchars($value, ENT_QUOTES, 'UTF-8', FALSE));
    }
