Bug #67298 for HTML-TreeBuilder-XPath: HTML "section" tag cannot be found

Subject:

HTML "section" tag cannot be found

I am looking at a document (http://www.makeuseof.com/tag/roundup-15-free-must-install-programs-for-your-new-pc/) which contains an HTML 5 element "section". I wanted a path that would extract one of these, so I used the XPath expression //section[contains(@class, "post-full")] However this doesnt seemt o match with HTML::TreeBuilder::XPath. I suspect it could be due to an underlying library (HTML::Tree, HTML::ELement??) not knowing about "section"?? Many thanks James

The problem is in HTML::Tagset. As section is not defined there as being a proper HTML element, it is not recognized by the parser, and it is silently discarded. I submitted a ticket on HTML::Tagset: https://rt.cpan.org/Ticket/Display.html?id=67299 If I get an answer from the maintainer of the module I will look into a patch, as this seems quite important to me, I know there is an HTML::HTML5 namespace on CPAN, but I would think that most people expect the HTML::* modules to work with whatever HTML is thrown at them.
