Monks, I was trying to use HTML::Element to modify a HTML tree but I ran into a difficulty. What I am trying to do is go through the tree, and whenever I find a link that matches a certain pattern, I want to remove the link

My code

if need_to_get_rid_of($node){
  print $node->findvalue('text()')." ".$node->findvalue('@href')."\n";
  $node->attr('@href', undef);
  print $node->findvalue('text()'). " ".$node->findvalue('@href')."\n"
+;
}

Am I just using $node->attr('attr','val') wrong? Is it simply a case of misinterpreting directions? Please help.
