template<class _Data >

void zypp::xml::rnParse	(	const InputStream &	input_r,
		_Data &	data_r
	)		`[inline]`

Parse xml input_r and store data in data_r.

_Data must be defaultconstructible and assignable.

_Data::RootNode must be a xml::ParseDef constructible from _Data&.

Exceptions:

ParseDefException on parse errors.

To parse a xml file like this:

 <test>
   <setup attr="13">value</setup>
   <list name="A"/>
   <list name="b"/>
 </test>

You need something like this:

  struct XmlData
  {
    // data
    unsigned              attr;
    std::string           value;
    std:list<std::string> names;

    public:
      // Convenience parsing to *this.
      void parse( const Pathname & path_r )
      { xml::rnParse( path_r, *this ); }

    public:
      // Parser description
      struct RootNode : public xml::ParseDef
      {
        RootNode( XmlData & data )
          : ParseDef( "test", MANDTAORY )
          , _data( data )
        {
          (*this)
              ("setup", MANDTAORY,
                        xml::parseDefAssign( data.value )
                                           ( "attr", data.attr ) )
              // Each individual list entry is collected locally
              // and appended to the list after the node is done.
              ("list",  MULTIPLE_OPTIONAL,
                        xml::parseDefAssign( "name", _cname )
                                           >> bind( &RootNode::cdone, this, _1 ) )
              ;
        }

        void cdone( const xml::Node & node_r )
        {
          _data.push_back( _cname );
          _cname.clear(); // prepare for next
        }

        private:
          XmlData &   _data; // stored just because notification callbacks are used.
          std::string _cname;
      };
  };

  XmlData xmlData;
  xmlData.parse( "/tmp/mytest.xml" );
