setOutputProperty(), setParameter() and setURIResolver() methods of javax.xml.transform.Transformer

Question

What is the use of the methods setOutputProperty() , setParameter() and setURIResolver() of the class javax.xml.transform.Transformer ? I had went through the official documentation and many other online resources, but I was unable to understand it clearly.

Answer 1

It's not obvious from the documentation because they don't link it prominently (but subtly), but setOutputProperty refers to OutputKeys , and those values can be used for the property names (and contain information about what they do, like control the indentation of the output).

setParameter makes a parameter value available to the transform; see XSL Transformation in Java with parameters .

setURIResolver allows the caller to specify how to find URIs. This might, for example, be used to load public identifiers like -//OASIS//DTD DocBook XML//EN ; see Formal Public Identifier , or to load network resources from a local filesystem or database.
