java.lang.Object org.apache.xml.serialize.BaseMarkupSerializer org.apache.xml.serialize.HTMLSerializer
public class HTMLSerializer
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:

ContentHandler
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:
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.

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