v.2.7.0 loading html with ALLOW_DUPLICATE_IDS returns empty document #63
Description
In a project of mine, I am using version 2.7.0.
After loading a html page with ALLOW_DUPLICATE_IDS
with something like
$this->domdocument->loadHTML( $htmlsource, HTML5DOMDocument::ALLOW_DUPLICATE_IDS );
it seems that the parser always returns an empty page.
The output of $this->domdocument->saveHTML() is somthing similar to:
<!DOCTYPE html>
<!--?xml encoding="utf-8" ?--><html lang="it-IT">
<head></head></html>
or
<!DOCTYPE html>
<!--?xml encoding="utf-8" ?--><html lang="en-US">
<head></head></html>
or
<!DOCTYPE html>
<!--?xml encoding="utf-8" ?--><html class="no-js alert__has-cookie" lang="en-US">
<head></head></html>
EDIT: The problem show in a machine with libxml2-2.14.6 installed and I think the issue is related to libxml2 version
