Method first_node

include/cereal/external/rapidxml/rapidxml.hpp:949–962

Gets first child node, optionally matching node name. \param name_ Name of child to find, or 0 to return first child regardless of its name; this string doesn't have to be zero-terminated if name_size is non-zero \param name_size_ Size of name, in characters, or 0 to have size calculated automatically from string \param case_sensitive Should name comparison be case-sensitive; non case-sensitive co

        //! \param case_sensitive Should name comparison be case-sensitive; non case-sensitive comparison works properly only for ASCII characters
        //! \return Pointer to found child, or 0 if not found.
