[Xsh-users] can not get sort to sort at all

[Heiko B. <he...@bl...>]

Hello,

whatever i try, sort is a complete NOP for me ;-) and i thought my  
intention was pretty simple...
all i wanted is to get a sorted list of the @bp:id 's of two files, like

$OLD := open $old_file;
$NEW := open $new_file;
$ids := sort ($OLD//bp:device/@bp:id | $NEW//bp:device/@bp:id) ;
print ($OLD//bp:device/@bp:id | $NEW//bp:device/@bp:id) ;
print "ids: " $ids;

1 2 3 4 5 6 7 8 9 1 2 3 4 5 9 7 8
ids:  1 1 2 2 3 3 4 4 5 5 6 7 9 8 7 9 8

umh... then i tried all kinds of things with :k and :n in the script  
and interactively (see below), but
never i got it to change anything at all. seems i have a fundamental  
misunderstandig here?

TIA, heiko
