IAttributeSequenceHandler, ICDATASectionHandler, ICommentHandler, IDocTypeHandler, IDocumentHandler, IElementHandler, IMarkupHandler, IProcessingInstructionHandler, ITextHandler, IXMLDeclarationHandlerpublic final class BlockSelectorMarkupHandler extends AbstractMarkupHandler
Implementation of IMarkupHandler able to apply block selection based on a set
of specified markup selectors (see org.attoparser.select).
Block selection means that once an element is selected by any of the specified selectors, the entire subtree of that element is also considered selected.
This markup handler will apply the specified markup selectors and divide parsing events
between two (possibly different) chained markup handlers implementing IMarkupHandler:
the selectedHandler and the nonSelectedHandler. Also, document start/end events will be
sent to the selectedHandler unless specified otherwise by means of the
setDocumentStartEndHandler(org.attoparser.IMarkupHandler) method.
Additionally, this handler will update the ParseSelection object currently in use
by the handler chain (which has been set to handlers by means of the
IMarkupHandler.setParseSelection(ParseSelection) method). For every event fired
on the delegated handlers, the parse selection object will contain up-to-date information about the selectors
(at every active selection level) that are currently matching the delegated events.
Also note that this filtering will be done in the most memory-efficient way, without the need to create any large extra String or char[] objects apart from a minimal element buffer object which will be reused throughout all the parsing process. This makes the execution of this handler extremely fast and integrated with the parsing process itself.
In order to see how this handler works we can see some examples. For instance, given the following markup:
<!DOCTYPE html>
<html>
<body>
<h1>AttoParser</h1>
<div class="content">
AttoParser is able to select <strong>just a fragment of markup</strong>.
</div>
</body>
</html>
...and a BlockSelectorMarkupHandler initialized with:
OutputMarkupHandler object as selectedHandler.DiscardMarkupHandler object as nonSelectedHandler. This
is the default non-selected handler used when none is specified.Using selector "div.content", we would get:
<div class="content">
AttoParser is able to select <strong>just a fragment of markup</strong>.
</div>
If we had two selectors, "h1" and "div//text()", we would get:
<h1>AttoParser</h1>
AttoParser is able to select just a fragment of markup.
Have a look at the package info for org.attoparser.select for a complete explanation on
markup selector syntax.
Note that, as with most handlers, this class is not thread-safe. Also, instances of this class should not be reused across parsing operations.

DuplicateMarkupHandler.

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.

IMarkupHandler
Sets the ParseStatus object that will be used during the parsing operation. This
object can be used for instructing the parser about specific low-level conditions arisen during event
handling.
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 and very specific scenarios in which this kind of interaction with the parser would be needed. It is therefore mainly for internal use.

IElementHandlerCalled when the end of an open element (an open tag) is found.
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.

IProcessingInstructionHandlerCalled when a Processing Instruction is found.
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.
