in reply to New Line of Modules

Says japhy:
YAPE::HTML, which was my attempt at producing a dependable HTML parser and tree-builder.

Why would I want to use YAPE::HTML instead of HTML::TreeBuilder?

    Using my module, I can reproduce the HTML I was given and supress the printing of certain tags, and print tags only to a given level: 
    use YAPE::HTML;
$p = YAPE::HTML->new($CONTENT);

1 while $p->next;  # to build the tree

@exclude = qw( a img );
$level = 2;

for ($p->root) {  # top-level elements
  print $_->fullstring(\@exclude, $level);
}

    I'm adding a feature to change it from allowing an exclude list to allowing either an exclude list or an "exclude all except..." list. If the previous code was given: 
    <b>Hi <i>there <s>folks!</s></i></b>

<br><br>

Visit my <img src="naked_woman.jpg"><a
href="http://www.pornsite.com/">porn site</a>!

    [download]
    then output would be: 
    <b>Hi <i>there folks!</i></b>

<br><br>

Visit my porn site!

    The <s> tag was removed because it was 3 layers down, and I requested only 2 layers.
