Question

I am doing a lot of XML parsing/transformation using the org.w3c.dom classes.

A Document object provides a lot of handy methods for traversing a document
that are not available to a Node object (e.g. getElementsByTagName(String)). Quite often I find myself getting Node elements and wanting to use the
convenience methods of Document on the child Node instances (one node at a time).

Is there any way I can convert a Node to a Document?

The
Document.adoptNode(Node)
or
Document.importNode(Node,boolean)
seems to provide what I want, but I cannot figure how to get an
instance of a blank Document in which to embed the node. Is there a way to get
a blank Document?

Or am I thinking about/approaching this in an entirely wrong way?

Invitatons to RTFM (pointing to a specific method/class that can clear my
conundrum) would be welcome, as well as any other thoughts or strategies.

Answer 1

getElementsByTagName() returns a NodeList, but every item of the node list is an instance of Element. And Element also has a getElementsByTagName() method.

Just cast the nodes from the node list to Element.
