=head1 NAME

Web::Scraper::LibXML - Drop-in replacement for Web::Scraper to use LibXML

=head1 SYNOPSIS

  use Web::Scraper::LibXML;

  # same as Web::Scraper
  my $scraper = scraper { ... };

=head1 DESCRIPTION

Web::Scraper::LibXML is a drop-in replacement for Web::Scraper to use
the fast libxml-based HTML tree builder, HTML::TreeBuilder::LibXML.

This is almost identical to HTML::TreeBuilder::LibXML's
I<replace_original> installer, like:

  use HTML::TreeBuilder::LibXML;
  HTML::TreeBuilder::LibXML->replace_original();
  
  use Web::Scraper;
  my $scraper = scraper { ... };
  # this code uses LibXML parser

which overrides HTML::TreeBuilder::XPath's new() constructor so that
L<ALL> of your code using HTML::TreeBuilder::XPath is switched to the
libxml based parser.

This module, instead, gives you more control over which TreeBuilder to
use, depending on the site etc.
