Of course that depends upon how general this needs to be.  If it will  
always be  the first part of the first parameter to a call to  
Math.ceil and negated, then:

======================================================================
text = <<EOS
<td>Traffic left:</td><td
align 
= 
right><b><script>document.write(setzeTT(""+Math.ceil(-123313/1000)));</ 
script>
MB</b></td>
EOS

m = text.match(/Math\.ceil\(\-(\d+)/)
puts m[1] if m
======================================================================


Of course, it seems "suspicious that you don't want to pick up the  
minus, and this seems to take a lot of consistency for granted.  For a  
good answer, you'll need to specify what conditions will always be the  
same.
