Detailed Description

template<class T>
class drain::TreePruner< T >

Example:

drain::TreePruner<drain::image::TreeSVG> textPruner;
Remove all TEXT elements which have neither children neither own text.

textPruner.tagSelector[svg::TSPAN] = drain::XmlEmptiness::TEXT;
textPruner.tagSelector[svg::UNDEFINED] = 0;
