Hi , The code for the variable width look_ahead assertion is

$product = "MOTOROLAx|xx|xx|x01-01-1900x|xYx|xx"; $product =~ s/(?<=\|)xx(?=(\||$))/x x/g; print "[ $product ]\n"; __END__ [ MOTOROLAx|x x|x x|x01-01-1900x|xYx|x x ]


The paranthesis was not there ,thanks Enlil for your help on finding this .
