Java documentbuilder.parse #document null

Your real problem is your interpretation of the output - you got a Document object ok - the null comes from the toString interpretation of a Document object. You should become familiar with the org. Node JavaDocs. There is a very useful table there showing what the "value" of every Node type is.

For a Document Node, that is always null. I figured out what my particular problem was. The code I had posted was combined for simplicity's sake. Skip navigation links. Object javax. Using this class, an application programmer can obtain a Document from XML. Obtain an instance of a DOMImplementation object. Specify the ErrorHandler to be used by the parser. Reset this DocumentBuilder to its original configuration. An IllegalArgumentException is thrown if the File is null null. I am fixing a bug on an existing code concerning DocumentBuilder.
