Detailed Description

Matches HTML elements that have a certain amount of children of type element (excluding text nodes, document nodes and others).

Example:

GumboNode * none = ...; // <div>Text nodes are ignored</div>
GumboNode * two  = ...; // <ul><li>first</li><li>last</li></ul>
 
ChildCountMatch m_none(/* child count *&zwj;/ 0);
ChildCountMatch m_two (/* child count *&zwj;/ 2);
 
assert( m_none.matches(none));
assert(!m_none.matches(two));
 
assert( m_two.matches(two));
assert(!m_two.matches(none));
