Subject: Re: [xsl] RuntimeException : Programmers's assertion from xsl transform From: "Simon Kelly" <kelly@xxxxxxxxxx> Date: Fri, 4 Jul 2003 14:25:09 +0200 |
I'm having a struggle to pin point the run-time error with this. I have narrowed it down to in being caused by a test="" statement, with a quick search of the net. But I cannot see any problem with any of my test statements. Could someone see if they can spot the bloomer! test="$image-node-list" -- Requires a return of true if list is not null. test="not($image-node-list)" -- Require a return of true if list is null test="($finish - $start) = $images-across" test="$start = $finish" test="$start < $finish" -- Obvious returns, all values are numbers. test="$image-node-list[$start]/link" -- Requires true if link node exists test="$image-node-list[$start][position() = last()]" -- Require true if the node at position $start is the last node in node set As always, all help greatfully recieved.
