Class HTMLSerializer

java.lang.Object

org.apache.xml.serialize.BaseMarkupSerializer

org.apache.xml.serialize.HTMLSerializer

All Implemented Interfaces:

DOMSerializer, Serializer, ContentHandler, DocumentHandler, DTDHandler, DeclHandler, LexicalHandler

Direct Known Subclasses:

XHTMLSerializer

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.

public class HTMLSerializer
extends BaseMarkupSerializer

Implements an HTML/XHTML serializer supporting both DOM and SAX pretty serializing. HTML/XHTML mode is determined in the constructor. For usage instructions see Serializer.

If an output stream is used, the encoding is taken from the output format (defaults to UTF-8). If a writer is used, make sure the writer uses the same encoding (if applies) as specified in the output format.

The serializer supports both DOM and SAX. DOM serializing is done by calling BaseMarkupSerializer.serialize(org.w3c.dom.Element) and SAX serializing is done by firing SAX events and using the serializer as a document handler.

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 DocumentHandler.endDocument().

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.

XHTML is slightly different than HTML:

• Element/attribute names are lower case and case matters
• Attributes must specify value, even if empty string
• Empty elements must have '/' in empty tag
• Contents of SCRIPT and STYLE elements serialized as CDATA

Constructor Detail

HTMLSerializer

protected HTMLSerializer(boolean xhtml,
              OutputFormat format)

Deprecated.

Constructs a new HTML/XHTML serializer depending on the value of xhtml. The serializer cannot be used without calling BaseMarkupSerializer.setOutputCharStream(java.io.Writer) or BaseMarkupSerializer.setOutputByteStream(java.io.OutputStream) first.

Parameters:

xhtml - True if XHTML serializing

HTMLSerializer

public HTMLSerializer()

Deprecated.

Constructs a new serializer. The serializer cannot be used without calling BaseMarkupSerializer.setOutputCharStream(java.io.Writer) or BaseMarkupSerializer.setOutputByteStream(java.io.OutputStream) first.

HTMLSerializer

public HTMLSerializer(OutputFormat format)

Deprecated.

Constructs a new serializer. The serializer cannot be used without calling BaseMarkupSerializer.setOutputCharStream(java.io.Writer) or BaseMarkupSerializer.setOutputByteStream(java.io.OutputStream) first.

HTMLSerializer

public HTMLSerializer(Writer writer,
              OutputFormat format)

Deprecated.

Constructs a new serializer that writes to the specified writer using the specified output format. If format is null, will use a default output format.

Parameters:

writer - The writer to use

format - The output format to use, null for the default

HTMLSerializer

public HTMLSerializer(OutputStream output,
              OutputFormat format)

Deprecated.

Constructs a new serializer that writes to the specified output stream using the specified output format. If format is null, will use a default output format.

Parameters:

output - The output stream to use

format - The output format to use, null for the default

Method Detail

setOutputFormat

public void setOutputFormat(OutputFormat format)

Deprecated.

Description copied from interface: Serializer

Specifies an output format for this serializer. It the serializer has already been associated with an output format, it will switch to the new format. This method should not be called while the serializer is in the process of serializing a document.

Specified by:

setOutputFormat in interface Serializer

Overrides:

setOutputFormat in class BaseMarkupSerializer

Parameters:

format - The output format to use

setXHTMLNamespace

public void setXHTMLNamespace(String newNamespace)

Deprecated.

startElement

public void startElement(String namespaceURI,
                String localName,
                String rawName,
                Attributes attrs)
                  throws SAXException

Deprecated.

Throws:

SAXException

endElement

public void endElement(String namespaceURI,
              String localName,
              String rawName)
                throws SAXException

Deprecated.

Throws:

SAXException

endElementIO

public void endElementIO(String namespaceURI,
                String localName,
                String rawName)
                  throws IOException

Deprecated.

Throws:

IOException

characters

public void characters(char[] chars,
              int start,
              int length)
                throws SAXException

Deprecated.

Specified by:

characters in interface ContentHandler

Specified by:

characters in interface DocumentHandler

Overrides:

characters in class BaseMarkupSerializer

Throws:

SAXException

startElement

public void startElement(String tagName,
                AttributeList attrs)
                  throws SAXException

Deprecated.

Throws:

SAXException

endElement

public void endElement(String tagName)
                throws SAXException

Deprecated.

Throws:

SAXException

startDocument

protected void startDocument(String rootTagName)
                      throws IOException

Deprecated.

Called to serialize the document's DOCTYPE by the root element. The document type declaration must name the root element, but the root element is only known when that element is serialized, and not at the start of the document.

This method will check if it has not been called before (BaseMarkupSerializer._started), will serialize the document type declaration, and will serialize all pre-root comments and PIs that were accumulated in the document (see BaseMarkupSerializer.serializePreRoot()). Pre-root will be serialized even if this is not the first root element of the document.

Throws:

IOException

serializeElement

protected void serializeElement(Element elem)
                         throws IOException

Deprecated.

Called to serialize a DOM element. Equivalent to calling startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes), endElement(java.lang.String, java.lang.String, java.lang.String) and serializing everything inbetween, but better optimized.

Specified by:

serializeElement in class BaseMarkupSerializer

Parameters:

elem - The element to serialize

Throws:

IOException - An I/O exception occured while serializing

characters

protected void characters(String text)
                   throws IOException

Deprecated.

Description copied from class: BaseMarkupSerializer

Called to print the text contents in the prevailing element format. Since this method is capable of printing text as CDATA, it is used for that purpose as well. White space handling is determined by the current element state. In addition, the output format can dictate whether the text is printed as CDATA or unescaped.

Overrides:

characters in class BaseMarkupSerializer

Parameters:

text - The text to print

Throws:

IOException - An I/O exception occured while serializing

getEntityRef

protected String getEntityRef(int ch)

Deprecated.

Description copied from class: BaseMarkupSerializer

Returns the suitable entity reference for this character value, or null if no such entity exists. Calling this method with '&' will return "&".

Specified by:

getEntityRef in class BaseMarkupSerializer

Parameters:

ch - Character value

Returns:

Character entity name, or null

escapeURI

protected String escapeURI(String uri)

Deprecated.
