## [Groovy] Class StreamingMarkupBuilder

- groovy.xml.StreamingMarkupBuilder

-     class StreamingMarkupBuilder
      extends AbstractStreamingBuilder

  A builder class for creating XML markup. This implementation uses a StreamingMarkupWriter to handle output.

  Example:

      System.out << new StreamingMarkupBuilder().bind {
         root {
           a( a1:'one' ) {
             b { mkp.yield( '3 < 5' ) }
             c( a2:'two', 'blah' )
           }
         }
       }

  Will output the following String, without newlines or indentation:

      <root>
         <a a1='one'>
           <b>3 &lt; 5</b>
           <c a2='two'>blah</c>
         </a>
       </root>

  Notes:
  - that `mkp` is a special namespace used to escape away from the normal building mode of the builder and get access to helper markup methods 'yield', 'pi', 'comment', 'out', 'namespaces', 'xmlDeclaration' and 'yieldUnescaped'.
  - Note that tab, newline and carriage return characters are escaped within attributes, i.e. will become , and respectively

    - #### Object builder

    - #### Object commentClosure

      Invoked by calling `mkp.comment`

    - #### Object declarationClosure

      Invoked by calling `mkp.xmlDeclaration`

    - #### Object encoding

    - #### boolean expandEmptyElements

    - #### Object noopClosure

      Invoked by calling `mkp.yield`. Used to render text to the output stream. Any XML reserved characters will be escaped to ensure well-formedness.

    - #### Object pendingStack

    - #### Object piClosure

      Invoked by calling `mkp.pi`

    - #### Object tagClosure

    - #### Object unescapedClosure

      Invoked by calling `mkp.yieldUnescaped`. Used to render literal text or markup to the output stream. No escaping is done on the output.

    - #### boolean useDoubleQuotes

  - ### Method Detail

    - #### Object bind(Object closure)

      Returns a Writable object, which may be used to render the markup directly to a String, or send the output to a stream.

      Examples:

           // get the markup as a string:
           new StreamingMarkupBuilder().bind { div { out << "hello world" } }.toString()

           // send the output directly to a file:
           new StreamingMarkupBuilder().bind { div { out << "hello world" } } \
                .writeTo( new File('myFile.xml').newWriter() )

      Returns:
        a Writable to render the markup

    - #### Object bindNode(Object node)

      Convenience method for binding a single node. The call `bindNode(node)` is equivalent to `bind{ out << node }`. Returns a Writable object, which may be used to render the markup directly to a String, or send the output to a stream.

      See Also:
        bind(Closure)
      Returns:
        a Writable to render the markup

    - #### Object getQt()
