| // Sep 14, 2000: |
| // Fixed serializer to report IO exception directly, instead at |
| // the end of document processing. |
| // Reported by Patrick Higgins <phiggins@transzap.com> |
| // Aug 21, 2000: |
| // Fixed bug in startDocument not calling prepare. |
| // Reported by Mikael Staldal <d96-mst-ingen-reklam@d.kth.se> |
| // Aug 21, 2000: |
| // Added ability to omit DOCTYPE declaration. |
| // Sep 1, 2000: |
| // If no output format is provided the serializer now defaults |
| // to ISO-8859-1 encoding. Reported by Mikael Staldal |
| // <d96-mst@d.kth.se> |

| /** |
| * Implements an HTML/XHTML serializer supporting both DOM and SAX |
| * pretty serializing. HTML/XHTML mode is determined in the |
| * constructor. For usage instructions see {@link Serializer}. |
| * <p> |
| * If an output stream is used, the encoding is taken from the |
| * output format (defaults to <tt>UTF-8</tt>). If a writer is |
| * used, make sure the writer uses the same encoding (if applies) |
| * as specified in the output format. |
| * <p> |
| * The serializer supports both DOM and SAX. DOM serializing is done |
| * by calling {@link #serialize} and SAX serializing is done by firing |
| * SAX events and using the serializer as a document handler. |
| * <p> |
| * If an I/O exception occurs while serializing, the serializer |
| * will not throw an exception directly, but only throw it |
| * at the end of serializing (either DOM or SAX's {@link |
| * org.xml.sax.DocumentHandler#endDocument}. |
| * <p> |
| * For elements that are not specified as whitespace preserving, |
| * the serializer will potentially break long text lines at space |
| * boundaries, indent lines, and serialize elements on separate |
| * lines. Line terminators will be regarded as spaces, and |
| * spaces at beginning of line will be stripped. |
| * <p> |
| * XHTML is slightly different than HTML: |
| * <ul> |
| * <li>Element/attribute names are lower case and case matters |
| * <li>Attributes must specify value, even if empty string |
| * <li>Empty elements must have '/' in empty tag |
| * <li>Contents of SCRIPT and STYLE elements serialized as CDATA |
| * </ul> |
| * |
| * @deprecated This class was deprecated in Xerces 2.6.2. It is |
| * recommended that new applications use JAXP's Transformation API |
| * for XML (TrAX) for serializing HTML. See the Xerces documentation |
| * for more information. |
