[XML-SIG] xml.dom won't traverse the whole XML tree

[Alexandre CONRAD]

Hello,

I have a problem here traversing an XML file all the way through.

Here is my script file (copy/paste in a file an execute it, it should work).

When you execute it, as you can see, it get's stuck in the 1st 
"videolist" element. It should normaly keep on going. And I can't see 
what I'm doing wrong...

Any idea what's wrong ? Thanks in advance.

Best regards,
