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