RapidXml Appending and printing example

gistfile1.cpp

/*
  These must be included in rapidxml_print (at line 140) to make it work:
  
  template<class OutIt, class Ch>
  inline OutIt print_children(OutIt out, const xml_node<Ch> *node, int flags, int indent);
  
  template<class OutIt, class Ch>
  inline OutIt print_attributes(OutIt out, const xml_node<Ch> *node, int flags);
  
  template<class OutIt, class Ch>
  inline OutIt print_data_node(OutIt out, const xml_node<Ch> *node, int flags, int indent);
  
  template<class OutIt, class Ch>
  inline OutIt print_cdata_node(OutIt out, const xml_node<Ch> *node, int flags, int indent);
  
  template<class OutIt, class Ch>
  inline OutIt print_element_node(OutIt out, const xml_node<Ch> *node, int flags, int indent);
  
  template<class OutIt, class Ch>
  inline OutIt print_declaration_node(OutIt out, const xml_node<Ch> *node, int flags, int indent);

  template<class OutIt, class Ch>

  template<class OutIt, class Ch>
  inline OutIt print_pi_node(OutIt out, const xml_node<Ch> *node, int flags, int indent);
  
  On g++.
  Not sure on VC tbh
