public class XMLEncoder
extends Object

A helper class to encode objects to XML.

Usage:

      XMLEncoder encoder = new XMLEncoder(writer);
      encoder
          .start("tag").attribute("name", "tag_name_attribute")
          .start("nested_tag").attribute("name", "nested_tag_name).cdata("tag text element").end()
          .end();
 

Since:

1.1, 4.1 API is greatly reworked to be more usable
