One method is to maintain a 'stack' of the elements in an array. This way your start/end element handlers can know what kind of element their parent (If there is one) is. A good tutorial that provides an example of this is at http://www.zend.com/zend/art/parsing.php Specifically, I recommend reading through the section on Representing the Document Structure, which explains the process.
