java - Formatting XML file using StAX

Question

I am using StAX XML stream writer to write the XML file. It writes all the data in a single line. I want all the tags to be indented instead of a single line.

Answer 1

stax-utils provides class IndentingXMLStreamWriter which does the job:

XMLStreamWriter writer =
  XMLOutputFactory.newInstance().createXMLStreamWriter(...);
writer = new IndentingXMLStreamWriter(writer);
