Many of the tools used to parse HTML use HTML::Parser under the hood, and it is worthwhile knowing how it works. This script gathers up all the content of each list item, including other elements, into a variable. When it meets the closing list item tag, you can do what you need to the content before printing it out.
use HTML::Parser; my $inside_li = 0; my $list_item = ''; sub start { my ($tag, $text) = @_; if ($inside_li) { $list_item .= $text; return; } if ($tag eq 'li') { $inside_li = 1; } print $text; }; sub text { my ($text) = @_; if ($inside_li) { $list_item .= $text; return; } print $text; }; sub end { my ($tag, $text) = @_; if ($tag eq 'li') { $inside_li = 0; # do things to <li> content $list_item =~ s/^\s+//; print $list_item; $list_item = ''; } if ($inside_li) { $list_item .= $text; return; } print $text; }; my $parser = HTML::Parser->new( api_version => 3, start_h => [\&start, "tagname, text"], text_h => [\&text, "text"], end_h => [\&end, "tagname, text"], default_h => [\&text, "text"], ); $parser->parse_file(\*DATA);

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
