Detailed Description

Matches if the result of applying a given MatchFunction to an HTML node returns true.

Example:

GumboNode * div  = ...; // <div>This is a div!</div>
GumboNode * span = ...; // <span>This is a span!</span>
 
MatchFunction is_div = [](const GumboNode * node) {
  return node->type == GUMBO_NODE_ELEMENT &&
         node->v.element.tag == GUMBO_TAG_DIV;
};
 
FunctionMatch m_is_div(is_div);
 
assert( m_is_div.matches(div));
assert(!m_is_div.matches(span));
