Re: Parsing HTML/XML with Regular Expressions (HTML::TreeBuilder::XPath)

in reply to Parsing HTML/XML with Regular Expressions

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
