NAME

HTML::Element::Replacer - Simplify the HTML::Element clone() - push_content() ritual

SYNOPSIS

 use HTML::Element::Replacer;

 {
  my $replacer = HTML::Element::Replacer->new(tree => $tree, look_down => [ scla => 'mid' ]);

  for my $data (@data) {
    $replacer->push_clone->defmap(attr_name => $data); # clone and push onto @temp_list
  }
 }
 # by default Replacer replaces... so it removes the element you were push_clone()ing

DESCRIPTION

Let's say you have this HTML:

<table>

  <tr scla="top"/> 

  <tr scla="mid"> 
    <td kmap="brand"> blah </td>
    <td kmap="age"> blah </td>
  </tr>

  <tr scla="bot"/> 

</table>

Now let's say you have 5 data rows that you wish to display using the middle tr as your sample. The pure HTML::Tree way to do this would be:

my $sample_tr = $tree->look_down(scla => 'mid');

my @c;
for my $data (@data) {
   my $c = $sample_tr->clone; 
   $c->defmap(kmap => $data);
   push @c, $c;
}

$sample->replace_with(@c);

We did cheat a bit by using defmap() from HTML::Element::Library. Now, with this class, we can do this:

 { 	
    my $replacer = HTML::Element::Replacer->new(look_down => [ scla => 'mid' ]);
 
    for my $data (@data) {
	my $clone = $replacer->push_clone->defmap(kmap => $data); # clone and push onto @temp_list
    }

 } # replacer goes out of scope and then replaces sample_tr
