Decode GPS NMEA code using arduino

Question

I know this has been asked many times but I really can't find what I am really searching.

I am using an Arduino Uno and a GPS Shield that shows GPS data through serial.

Here is the code I am uploading to my Arduino to interface the GPS Shield:

void loop() // run over and over
{
    while(!(mySerial.available())){}
      Serial.write(mySerial.read());
}

That is just the code. Nevertheless, as it continuously loops, on a Serial Monitor, it also output GPS data every second.

Here is its output every second:

$GPGGA,013856.000,000.9090,N,9090.90,E,1,09,1.1,316.97,M,0.00,M,,*66
$GPGSA,A,3,07,08,11,1ÿ3,16,19,23,27,42,,,,2.8,1.1,2.5*3F
$GPRMC,013856.000,A,000.9090,N,9090.90,E,0.0,038.1,310814,,,A*62
$GPGSV,ÿ3,1,12,16,26,059,33,27,33,025,44,08,30,330,32,07,31,326,34*7A
$GPGSV,3,2,12,19,58,354,31,01,33,186,18,23,32,221,24,11,5ÿ9,198,31*70
$GPGSV,3,3,12,42,60,129,32,13,38,253,27,32,06,161,,31,01,140,*7E

As it updates every second, the coordinates changes to minimal, which means the GPS Shield is working.

The problem here is, I wanted to parse the GPS data, especially on the GPGGA line only, and ignore the other lines. I would like to parse the Status, Latitude, N/S Indicator, Longitude, and E/W Indicator.

I have searched for the NMEA Library (http://nmea.sourceforge.net/), but I have no idea how to use it.

Can someone please help me here? Thank you.

I have searched the Internet, and the best answer would be using the "TinyGPS++" library for Arduino. Almost all GPS-related codes are already included on the Library.
