RapidXML问题

XML在编程中会经常应用

RapidXML就是用C++实现的一种XML工具

它是开源、灵活且高效的

仅仅由4个头文件组成，可以直接编译到项目当中。

rapidxml.hpp
rapidxml_utils.hpp
rapidxml_print.hpp
rapidxml_iterators.hpp

在Linux或者Qt等环境想使用rapidxml_print.hpp中的类会有声明的问题，所以可以在文件的104行处插入如下代码

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>
inline OutIt print_comment_node(OutIt out, const xml_node<Ch>* node, int flags, int indent);

template<class OutIt, class Ch>
inline OutIt print_doctype_node(OutIt out, const xml_node<Ch>* node, int flags, int indent);

template<class OutIt, class Ch>
inline OutIt print_pi_node(OutIt out, const xml_node<Ch>* node, int flags, int indent);
