in reply to XML::Twig removing tags from content

use strict; use XML::Rules; my $parser = XML::Rules->new(style => 'filter', rules => { _default => 'raw', p => sub { return $_[1]->{_content}}, }); $parser->filter(\*DATA); __DATA__ <li> <p> Some <b>text</b> </p> </li>

If you wanted to remove only <p> directly inside <li>, the code would look like this:

use strict; use XML::Rules; my $parser = XML::Rules->new(style => 'filter', rules => { _default => 'raw', p => sub { if ($_[2][-1] eq 'li') { return $_[1]->{_content}; } else { return $_[0] => $_[1]; } }, }); $parser->filter(\*DATA); __DATA__ <root> <li> <p> Some <b>text</b> </p> </li> <p> Other <b>text</b> </p> </root>

The $_[2] is a reference to an array containing the names of the opened tags, so the condition just checks whether the enclosing tag of the currently processed <p> is <li>.
