Using the XMLOutputter Class Directly

• Configured with three variables passed to the constructor:

  indent

  a String added at each level of output; e.g. two spaces or a tab

  lineSeparator

  the String to break lines with, no line breaking is performed if this is null or the empty string

  encoding

  The name of the encoding to use for output; e.g. UTF-16 or ISO-8859-1

• Options can be set with these 10 methods:

      public void setLineSeparator(String separator) {}
      public void setNewlines(boolean newlines) {}
      public void setEncoding(String encoding) {}
      public void setOmitEncoding(boolean omitEncoding) {}
      public void setOmitDeclaration(boolean omitDeclaration) {}
      public void setExpandEmptyElements(boolean expandEmptyElements) {}
      public void setIndent(String indent) {}
      public void setTextNormalize(boolean textNormalize)
      public void setTrimAllWhite(boolean trimAllWhite) {}
      public void setTextTrim(boolean textTrim) {}

• The output() method writes a Document onto a given OutputStream:

    public void output(Document doc, OutputStream out) throws IOException {}
    public void output(Document doc, Writer writer) throws IOException {}

• There are also output() methods for other JDOM classes:

    public void output(Element element, Writer out) throws IOException {}
    public void output(Element element, OutputStream out) {}
    public void outputElementContent(Element element, Writer out) throws IOException {}
    public void outputElementContent(Element element, OutputStream out) throws IOException {}
    public void output(CDATA cdata, Writer out) throws IOException {}
    public void output(CDATA cdata, OutputStream out) throws IOException {}
    public void output(Comment comment, Writer out) throws IOException {}
    public void output(Comment comment, OutputStream out) throws IOException {}
    public void output(Text text, Writer out) throws IOException {}
    public void output(Text text, OutputStream out) throws IOException {}
    public void output(Entity entity, Writer out) throws IOException {}
    public void output(Entity entity, OutputStream out) throws IOException {}
    public void output(ProcessingInstruction processingInstruction, Writer out)
      throws IOException {}
    public void output(ProcessingInstruction processingInstruction, OutputStream out)
     throws IOException {} 

• Use the outputString() methods to store a document in a string:

      public String outputString(Document doc) throws IOException {}
      public String outputString(Element element) throws IOException {}
      public String outputString(CDATA cdata) {}
      public String outputString(Comment comment) {}
      public String outputString(DocType doctype) {}
      public String outputString(EntityRef entity) {}
      public String outputString(ProcessingInstruction pi) {}
      public String outputString(Text text) {}
