Presumably you're talking about updating the user's browser window, not updating the XML file, correct? If so, this is a Javascript question, of updating via the HTML DOM, not a PHP or XML question.

You might want to ask in the JS forum.

basicaly the ticker -read- the xml and show the data. the xml is updated (the values are stock prices) and i whan't the users view the updated data as much time stay at the page, without refresh or reload the page.
