Detailed Description

Matches HTML nodes for which every given Match returns false.

Example:

GumboNode * attr_none = ...; // <hr/>
GumboNode * attr_one  = ...; // <h1 class="main-heading"></h1>
GumboNode * attr_two  = ...; // <div id="cart" class="my-cart"></div>
 
NegateMatch not_one (std::make_unique<AttributeCountMatch>(1));
NegateMatch not_none(std::make_unique<AttributeCountMatch>(0));
 
assert(!not_none.matches(attr_none));
assert( not_none.matches(attr_one));
assert( not_none.matches(attr_two));
 
assert( not_one.matches(attr_none));
assert(!not_one.matches(attr_one));
assert( not_one.matches(attr_two));
