In my
previous comment I mentioned that I could not find a way to pass the attribute
empty_element_tags from HTML::TreeBuilder to HTML::Parser. Looking at the source code for HTML::TreeBuilder I found this:
our @ISA = qw(HTML::Element HTML::Parser);
# This looks schizoid, I know...
So I've learnt something there! I can call
empty_element_tags(1) and now it works.
use HTML::TreeBuilder::XPath;
my $file = 'example.html';
my @result;
my $tree = HTML::TreeBuilder::XPath->new;
$tree->empty_element_tags(1); # calls this on HTML::Parser
$tree->parse_file($file);
$tree->eof;
my @divs = $tree->findnodes('//div[@class="data"]');
for my $div (@divs) {
my $text = $div->as_text || '';
$text =~ s/\W//g;
push(@result, $div->attr('id') . "=$text");
}
print join(', ',@result);
Output:
Zero=, One=Monday, Two=Tuesday, Three=Wednesday, Four=Thursday, Five=F
+riday, Six=Saturday, Seven=Sunday

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).
