You can define a dictionary to describe the object, and then return a
sequence of those:

  dictionary MyNodeInfo {
    Node node;
    float number1;
    float number2;
    float number3;
  };

  partial interface Document {
    sequence<MyNodeInfo> myFunction();
  };

Then:

  void nsIDocument::MyFunction(nsTArray<MyNodeInfo>& aResult) {
    MyNodeInfo* e = aResult.AppendElement();
    e->mNode = …;
    e->mNumber1 = …;
    …
  }
