HTML::TreeBuilder is bit slow for some use case. and, XML::LibXML is very fast! I want to use it. But, some libraries uses HTML::TreeBuilder. HTML::TreeBuilder::LibXML is drop-in-replacement for HTML::TreeBuilder::XPath. Currently, this module implements good enough methods for work with Web::Scraper.
