How I can get last child of an element through Twig Handler

Posted on 2008-12-25 08:51:55-08 by selvaperumaal

Hi, I have trying to get last child of an element using twig object by,

@last_tg=$t->get_xpath(tbody/row[last()]/entry);

its work well, but I need it in twig handler potion as

my $t = new XML::Twig ( twig_handlers => {'tbody/row[last()]/entry' => sub {$_->set_att('aid5:cellstyle'=>'TBL')} );

but it shows error like 'unrecognized expression in handler', is it possible using the 'last()' xpath function here? give me an idea for how I can get last child of an element through Twig Handler. Thanks in advance.

No, you can't use last() here. There is no way for the parser, at that point, to know that the child is the last one. You will have to set a handler on the parent (tbody here), and then you can access the last child.
