How to iterate over a vector of many stucts

[[email protected]]

I have many nodes, done data is stored in a struct like this:

  struct BriteNodeInfo
  {
    int nodeId;
    double xCoordinate;
    double yCoordinate;
    int inDegree;
    int outDegree;
    int asId;
    std::string type;
  };

Each node instance is stored in a vector like this:

  typedef std::vector<BriteNodeInfo> BriteNodeInfoList;

  BriteNodeInfoList m_briteNodeInfoList;

Problem: How do I wrire a function that write in a .txt file my node data like this:

nodeId0 yCoordinate0 xCoordinate0
nodeId1 yCoordinate1 xCoordinate1
nodeId2 yCoordinate2 xCoordinate2
nodeId3 yCoordinate3 xCoordinate3
etc...

I have tried but my iteration syntax is not good enough. Here is my function, please help:

void SaveNodeData (std::string fname)
{
  ofstream os(fname.c_str(), ios::trunc);

  vector<BriteNodeInfo> BriteNodeInfoList;
  BriteNodeInfoList m_briteNodeInfoList;

  for (BriteNodeInfoList::Iterator i = m_briteNodeInfoList.Begin(); i != m_briteNodeInfoList.End(); ++i)
    {  
        os << BriteNodeInfo[i].nodeId "\t" << "\t" << BriteNodeInfo[i].yCoordinate << "\t"BriteNodeInfo[i].xCoordinate<< "\n";
    }

    os << "\n";
 }
