## Class XmlNodePrinter

- java.lang.Object
- - groovy.util.XmlNodePrinter

-     public class XmlNodePrinter
      extends java.lang.Object

  Prints a `groovy.util.Node` (as used with `XmlParser`) including all children in XML format. Typical usage:

       def xml = '<html><head><title>Title</title></head><body><h1>Header</h1></body></html>'
       def root = new XmlParser().parseText(xml)
       new XmlNodePrinter(preserveWhitespace:true).print(root.body[0])

  which when run produces this on stdout (or use your own `PrintWriter` to direct elsewhere):

       <body>
         <h1>Header</h1>
       </body>
