示例1: getGeometryTypeOfElem

void ILI2Reader::SetFieldValues(OGRFeature *feature, DOMElement* elem) {
  int type = 0;
  //recursively search children
  for (DOMElement *childElem = (DOMElement *)elem->getFirstChild();
        type == 0 && childElem && childElem->getNodeType() == DOMNode::ELEMENT_NODE;
        childElem = (DOMElement*)childElem->getNextSibling()) {
    type = getGeometryTypeOfElem(childElem);
    if (type == 0) {
      if (childElem->getFirstChild() && childElem->getFirstChild()->getNodeType() == DOMNode::ELEMENT_NODE) {
        SetFieldValues(feature, childElem);
      } else {
        char *fName = fieldName(childElem);
        int fIndex = feature->GetFieldIndex(fName);
        if (fIndex != -1) {
          char * objVal = getObjValue(childElem);
          if (objVal == NULL)
            objVal = getREFValue(childElem); // only to try
