Didn't Peter explain it in his first mail?

$line is always a nodeset about all "prescriber-info/trade-name"s. $trade is
a nodeset only with the current one (the '.'). So the nodesets are always
different, the comparison between these two nodesets is false, you get
always ';'. But if you have only 1 trade-name, $trade contains this one and
$line too. Both nodesets contain this one node. They are equal, you get no
semi-colon.

Hope this helps ... and it's correctly explained. ;-)
