Can't these be static in the .cpp file?

As I'm using Node::document() method in nodeOrStringToNode method to create a
Text node, I'm not making this static. We can pass document() in this method. If
it will look fine then we can use it. Please share your opinion.

Oh, you need the Document to create the Text nodes. Never mind my suggestion
then.
