The IDLffDICOM::GetParent function method is used to find the parent references of a set of elements in a DICOM sequence.
Result = Obj->[IDLffDICOM::]GetParent(ReferenceList)
Returns the parent references of a set of elements in a DICOM sequence. It takes as an argument an array of references that represent DICOM elements. If no members of the ReferenceList are members of a sequence, a -1 is returned, and for each member of the ReferenceList which is not a member of a sequence, a -1 is returned.
An array of references to DICOM elements that are known to be members of a DICOM sequence.

obj = OBJ_NEW('IDLffDICOM')

; Get the reference to the Referenced Study Sequence
; element, if it exists:
ref = obj->GetReference('0008'x, '1110'x)
PRINT, ref
PRINT, obj->GetDescription(REFERENCE = ref)
; Get and print the parent sequence, if it exists.
; This should result in a -1 since this element is not
; a member of a sequence:
parent = obj->GetParent(ref)
PRINT, parent
PRINT, obj->GetDescription(REFERENCE=parent)
; Get the children of the Referenced Study Sequence
; element, if it exists:
refs = obj->GetChildren(ref[0])
PRINT, refs
