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:

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(java.lang.String newNamespace)
Deprecated. 

startElement

public void startElement(java.lang.String namespaceURI,
                         java.lang.String localName,
                         java.lang.String rawName,
                         Attributes attrs)
                  throws SAXException
Deprecated. 
Description copied from interface: ContentHandler
Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement event for every startElement event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement event.

This event allows up to three name components for each element:

  1. the Namespace URI;
  2. the local name; and
  3. the qualified (prefixed) name.

Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes properties:

Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted. The attribute list will contain attributes used for Namespace declarations (xmlns* attributes) only if the http://xml.org/sax/features/namespace-prefixes property is true (it is false by default, and support for a true value is optional).

Like characters(), attribute values may have characters that need more than one char value.

Parameters:
namespaceURI - the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed
localName - the local name (without prefix), or the empty string if Namespace processing is not being performed
rawName - the qualified name (with prefix), or the empty string if qualified names are not available
attrs - the attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. The value of this object after startElement returns is undefined
Throws:
SAXException - any SAX exception, possibly wrapping another exception

endElement

public void endElement(java.lang.String namespaceURI,
                       java.lang.String localName,
                       java.lang.String rawName)
                throws SAXException
Deprecated. 
Description copied from interface: ContentHandler
Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement event for every endElement event (even when the element is empty).

For information on the names, see startElement.

Parameters:
namespaceURI - the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed
localName - the local name (without prefix), or the empty string if Namespace processing is not being performed
rawName - the qualified XML name (with prefix), or the empty string if qualified names are not available
Throws:
SAXException - any SAX exception, possibly wrapping another exception

endElementIO

public void endElementIO(java.lang.String namespaceURI,
                         java.lang.String localName,
                         java.lang.String rawName)
                  throws java.io.IOException
Deprecated. 
Throws:
java.io.IOException

characters

public void characters(char[] chars,
                       int start,
                       int length)
                throws SAXException
Deprecated. 
Description copied from interface: ContentHandler
Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Individual characters may consist of more than one Java char value. There are two important cases where this happens, because characters can't be represented in just sixteen bits. In one case, characters are represented in a Surrogate Pair, using two special Unicode values. Such characters are in the so-called "Astral Planes", with a code point above U+FFFF. A second case involves composite characters, such as a base character combining with one or more accent characters.

Your code should not assume that algorithms using char-at-a-time idioms will be working in character units; in some cases they will split characters. This is relevant wherever XML permits arbitrary characters, such as attribute values, processing instruction data, and comments as well as in data reported from this method. It's also generally relevant whenever Java code manipulates internationalized text; the issue isn't unique to XML.

Note that some parsers will report whitespace in element content using the ignorableWhitespace method rather than this one (validating parsers must do so).

Specified by:
characters in interface ContentHandler
Specified by:
characters in interface DocumentHandler
Overrides:
characters in class BaseMarkupSerializer
Parameters:
chars - the characters from the XML document
start - the start position in the array
length - the number of characters to read from the array
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.

startElement

public void startElement(java.lang.String tagName,
                         AttributeList attrs)
                  throws SAXException
Deprecated. 
Description copied from interface: DocumentHandler
Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement() event for every startElement() event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement() event.

If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

Parameters:
tagName - The element type name.
attrs - The attributes attached to the element, if any.
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.

DocumentHandler.endElement(java.lang.String), AttributeList

endElement

public void endElement(java.lang.String tagName)
                throws SAXException
Deprecated. 
Description copied from interface: DocumentHandler
Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

If the element name has a namespace prefix, the prefix will still be attached to the name.

Parameters:
tagName - The element type name
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.
