Question

I have a simple question about Java’s XML API and I hope there’s a simple answer too:

Lets say that after processing I have the following XML output:

<a>     <b><c>     <d> <e> some content         </e>    </d>     </c>    </b> </a> 

The structure is correct but whitespaces are all over the place. The question is that how can I prettify the output so that it looks something like this:

<a>     <b>         <c>              <d>                 <e>some content</e>             </d>         </c>     </b> </a> 

Only catch is that I can’t use anything but Java 5’s own XML API.

Answer 1

Use Transformer.setOutputProperty(OutputKeys.INDENT, ‘yes’).
