Parsing a XML file

Hi i had been using XercersDomParser for parsing the XML file in C++
I am not familiar with XML. In the follwing XML file

http://localhost:8080/source/schemas/locomotive.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://localhost:8080/source/schemas/locomotive.xsd http://localhost:8080/source/schemas/locomotive.xsd">

Eventhough i can traverse through XML file through
DOMTreeWalker but can't get idea to store Values in a strucured

the structure look like this

typedef struct
{
Loco_Id LocoId ;
string /*DateTime*/ SampleTime ;
float Lattitude;
float Longitude;
float Speed ;
float Direction;
int KmPostPosition;
int TrackNumber;
int Alarms;
int Failures ;
}LocoDetails

Can any one tell how to access the value from the XML file and store to a list
