Description:
------------
The source in the PHP dom extension causes the LIBXML_NOWARNING flag to be ignored when loading html
through DOMDocument.
Problem is in ext/dom/document.c of PHP source, in the dom_load_html method.
Calling htmlCtxtUseOptions with HTML_PARSE_NOWARNING causes the warning handlers to be unregistered
(set to NULL). But the PHP code then proceeds to install its own handlers unconditionally, rendering
the flag useless.
see stackoverflow http://stackoverflow.com/questions/41860683/libxml-htmlparsedocument-ignoring-htmlparseoption-flags
Test script:
---------------
$doc=new DOMDocument();
$doc->loadHTML("<tagthatthrowswarning>HI</tagthatthrowswarning>",
LIBXML_NOWARNING);
echo $doc->saveHTML();
Expected result:
----------------
expected output
no warnings output.
Actual result:
--------------
E_WARNING : type 2 -- DOMDocument::loadHTML(): Tag tagthatthrowswarning invalid in Entity, line: 1
-- at line 4
