Re: global variable that contain a node-set

Robert,

That's working fine...

Here you're putting into the src attribute of the img element the
*content* of the image nodes you've collected.  Naturally enough,
they're empty elements so you end up putting nothing in.  Change the
XPath to:

<img src="&img_uri;/{$leftnav.imagenodes[@id='joinus'and
                                         @lang=/page/@lang]/@filename}"/>

and you'll see it's working fine :)

I hope that helps,

Jeni
