Convert dom4j.Element to dom4j.Document

Lets assume sometimes I got a dom4j Document and sometimes I got a dom4j Element. I want to apply the code of the following function 

public List<Element> getElements(Document doc4j){
//do
}

on my object of type Element as well. But that would only work if I can convert this Element to a Document. I cant use the method getDocument, because I only want to apply the code under //do for the sub tree which represented by the object of type Element.

Solution

  • From the docs, it looks like Document and Element both extend Branch, can you not make your method take a Branch as below?

    public List<Element> getElements(Branch branch) {
  //do
}
