tag span and script inside the inline web widget

The code embed is like :

<script src="/mywidget_inline"></script>

But the link /mywidget_inline return the code like that :

<span id="thmr_11" class="thmr_call">
  window.onload = function() {
  document.getElementById(widgetContext['widgetid']).innerHTML = ....;
};
</span>

<script type="text/javascript">jQuery.extend(Drupal.settings, {..... });</script>

So nothing displays.... :-(
how to delete theses tags (span and script) ?

Thks a lot.
