- Create an SoSearchAction
- Call setNode() with the address of the node
- Apply the action to the root of the scene graph
- Call getPath() to get an SoPath
- Call getIndexFromTail(0) to get the index (in its parent) of the node.

To get a pointer to the node's parent call getNodeFromTail(1).

Hello,

Then to be faster, you also can use this peace of code.

#include <Inventor/SoLists.h>
#include <Inventor/misc/SoNotification.h>

void buildHeadNodesList(SoNode* node, std::set<SoNode*>& nodelist)
{
  if (node != NULL)
  {
    SoAuditorList* al = (SoAuditorList*)&(node->getAuditors());
    int j;
    int numParent = 0;
    for ( j = 0; j < al->getLength(); j++ )
    {
      if (al->getType(j) == SoNotRec::PARENT)
      {
        SoNode* parentNode = (SoNode*)(al->getObject(j));
        if (parentNode != NULL)
        {
          buildHeadNodesList(parentNode, nodelist);
          numParent++;
        }
      }
    }
    if (numParent == 0)
      nodelist.insert(node);
  }
