                        );
                        response_x = response_map_x.get('response_x');
                        return response_x.GetCityForecastByZIPResult;
                    }
                }
            }

Answer 1

You can store the result in a apex property and create getters and setters for apex properties you want to display

To help you with an example here is a sample code to get you started

public class resultDisplayCtrl{
   public WeatherInformation.WeatherForecasts results {get;set;}

   public pagereference getData(){
     WeatherReportFromCdyne.WeatherSoap  obj = new WeatherReportFromCdyne.WeatherSoap (); 
     WeatherInformation.WeatherForecasts results = obj.GetCityWeatherByZIP('95007');
      return null;
   }

}

Note : Mark properties on your Weather Information class as getters and setters so you can display on the VF

example

public class WeatherForecasts {
                public Double Latitude {get;set;}
                public Double Longitude {get;set;}
                public Double AllocationFactor {get;set;}
                public String FipsCode {get;set;}
                public String PlaceName {get;set;}
                public String StateCode {get;set;}
                public String Status {get;set;}
                public WeatherInformation.ArrayOfWeatherData Details;
                private String[] Latitude_type_info = new String[]{'Latitude','http://www.webservicex.net',null,'1','1','false'};
                private String[] Longitude_type_info = new String[]{'Longitude','http://www.webservicex.net',null,'1','1','false'};
                private String[] AllocationFactor_type_info = new String[]{'AllocationFactor','http://www.webservicex.net',null,'1','1','false'};
                private String[] FipsCode_type_info = new String[]{'FipsCode','http://www.webservicex.net',null,'0','1','false'};
                private String[] PlaceName_type_info = new String[]{'PlaceName','http://www.webservicex.net',null,'0','1','false'};
                private String[] StateCode_type_info = new String[]{'StateCode','http://www.webservicex.net',null,'0','1','false'};
                private String[] Status_type_info = new String[]{'Status','http://www.webservicex.net',null,'0','1','false'};
                private String[] Details_type_info = new String[]{'Details','http://www.webservicex.net',null,'0','1','false'};
                private String[] apex_schema_type_info = new String[]{'http://www.webservicex.net','true','false'};
                private String[] field_order_type_info = new String[]{'Latitude','Longitude','AllocationFactor','FipsCode','PlaceName','StateCode','Status','Details'};
            }

Visualforce code

<apex:page controller="resultDisplayCtrl"> 
  <apex:commandbutton value="callWebservice" action="{!getData}"/>
  //write your vf markup to show each property from result set
  <!--Sample Tag-->
  <apex:outputtext value="{!result.Latitude}" />
  <apex:outputtext value="{!result.AllocationFactor}" />
</apex:page>
