Hi Igor,

Thanks for your reply.

Any pointers on how to do this? My compiler keeps complaining. This is
how I cast:

  NodeSet nodes_whitespace =
doc->get_root_node()->find("//text()[normalize-space()='']");
  for_each(nodes_whitespace.begin(), nodes_whitespace.end(),
      bind(&Node::remove_child,
        bind(static_cast<Node*(Node::*)()>(&Node::get_parent), _1)));

This is what my compiler thinks about it:

main.cpp: In function ‘void remove_whitespace_nodes(xmlpp::Document*)’:
main.cpp:58: error: invalid static_cast from type ‘<unresolved
overloaded function type>’ to type ‘xmlpp::Node* (xmlpp::Node::*)()’

How should I do this then?

Thank you,
Andrej
