public final class MinimizeHtmlMarkupHandler extends AbstractChainedMarkupHandler
Implementation of IMarkupHandler used for minimizing (compacting) HTML markup.
The minimization operations that can be performed are:
Note that, though theoretically possible per the HTML rules, no tags are created or removed during minimization in order to ensure the lowest impact (ideally zero, except for text white space) on the DOM of the resulting markup.
Two minimization modes are available:
MinimizeHtmlMarkupHandler.MinimizeMode.ONLY_WHITE_SPACE and
MinimizeHtmlMarkupHandler.MinimizeMode.COMPLETE. The former only minimizes
white space whereas the latter performs all the available minimizations.
Note that, as with most handlers, this class is not thread-safe. Also, instances of this class should not be reused across parsing operations.
Sample usage:
final Writer writer = new StringWriter();
// The output handler will be the last in the handler chain
final IMarkupHandler outputHandler = new OutputMarkupHandler(writer);
// The minimizer handler will do its job before events reach output handler
final IMarkupHandler handler = new MinimizeHtmlMarkupHandler(MinimizeMode.COMPLETE, outputHandler);
parser.parse(document, handler);
return writer.toString();

minimizeMode - the minimization mode to be used.next - the handler to which events will be delegated after minimization.public void setParseConfiguration(ParseConfiguration parseConfiguration)
IMarkupHandler
Sets the ParseConfiguration object that will be used during the parsing
operation. This object will normally have been specified to the parser object during its instantiation
or initialization.
This method is always called by the parser before calling any other event handling method.
Note that this method can be safely ignored by most implementations, as there are very few scenarios in which this kind of interaction would be consisdered relevant.

ITextHandlerCalled when a text artifact is found.
A sequence of chars is considered to be text when no structures of any kind are contained inside it. In markup parsers, for example, this means no tags (a.k.a. elements), DOCTYPE's, processing instructions, etc. are contained in the sequence.
Text sequences might include any number of new line and/or control characters.
Text artifacts are reported using the document buffer directly, and this buffer should not be considered to be immutable, so reported texts should be copied if they need to be stored (either by copying len chars from the buffer char[] starting in offset or by creating a String from it using the same specification).
Implementations of this handler should never modify the document buffer.

Artifacts are reported using the document buffer directly, and this buffer should not be considered to be immutable, so reported structures should be copied if they need to be stored (either by copying len chars from the buffer char[] starting in offset or by creating a String from it using the same specification).
Implementations of this handler should never modify the document buffer.

Three [offset, len] pairs are provided for three partitions (outer, target and content):

Note that, although XML Declarations have the same format as processing instructions, they are not considered as such and therefore are handled through a different handling method.
