PHP: Using simplexml to loop through all levels of an XML file

Question

I have a function which uses simplexml to return the first level of nodes in an XML file and write it into an unordered list:

function printAssetMap() {
             


        

Answer 1

you need to use a recursive function. here is an example that outputs an array from XML. It is from the PHP docs - http://www.php.net/manual/en/ref.simplexml.php. You can amend this to output a list.

children(); 
    $return = null; 
  } 

  foreach ($children as $element => $value) { 
    if ($value instanceof SimpleXMLElement) { 
      $values = (array)$value->children(); 

      if (count($values) > 0) { 
        $return[$element] = XMLToArray($value); 
      } else { 
        if (!isset($return[$element])) { 
          $return[$element] = (string)$value; 
        } else { 
          if (!is_array($return[$element])) { 
            $return[$element] = array($return[$element], (string)$value); 
          } else { 
            $return[$element][] = (string)$value; 
          } 
        } 
      } 
    } 
  } 

  if (is_array($return)) { 
    return $return; 
  } else { 
    return $false; 
  } 
} 
?>
