,IXMLDeclarationHandler
public final class SimplifierMarkupHandler extends AbstractMarkupHandler
Implementation of the
IMarkupHandler
interface aimed at converting the events launched through this interface to the simpler ones at theISimpleMarkupHandler
interface.Note that this handler, when not used as a part of a larger chain of handlers, can be more easily applied by making use of the
SimpleMarkupParser
class.Sample usage:
// Obtain a java.io.Reader on the document to be parsed final Reader documentReader = ...; // Create the handler instance. Extending the no-op AbstractSimpleMarkupHandler is a good start final ISimpleMarkupHandler simpleHandler = new AbstractSimpleMarkupHandler() { ... // some events implemented }; // Create a handler chain with the 'simplifier' handler, which will convert events from 'normal' to 'simple'. final IMarkupHandler handler = new SimplifierMarkupHandler(simpleHandler); // Create or obtain the parser instance (note this is not the 'simple' one!) final IMarkupParser parser = new MarkupParser(ParseConfiguration.htmlConfiguration()); // Parse it! parser.parse(documentReader, handler);
Note that, as with most handlers, this class is not thread-safe. Also, instances of this class should not be reused across parsing operations.

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.

- the offset (position in buffer) where the element name appears.nameLen
- the length (in chars) of the element name.line
- the line in the original document where the element ending structure appears.col
- the column in the original document where the element ending structure appears.- Throws:
ParseException
- if any exceptions occur during handling.

handleAttribute
public void handleAttribute(char[] buffer, int nameOffset, int nameLen, int nameLine, int nameCol, int operatorOffset, int operatorLen, int operatorLine, int operatorCol, int valueContentOffset, int valueContentLen, int valueOuterOffset, int valueOuterLen, int valueLine, int valueCol) throws ParseException
Description copied from interface:IAttributeSequenceHandler
Called when an attribute is found.
Three [offset, len] pairs are provided for three partitions (name, operator, valueContent and valueOuter):
class="basic_column"
[NAM]* [VALUECONTE]| (*) = [OPERATOR]
| [VALUEOUTER--]
[OUTER-------------]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.
- Specified by:
handleAttribute
in interfaceIAttributeSequenceHandler
- Overrides:
handleAttribute
in classAbstractMarkupHandler
- Parameters:
buffer
- the document buffer (not copied)nameOffset
- offset for the name partition.nameLen
- length of the name partition.nameLine
- the line in the original document where the name partition starts.nameCol
- the column in the original document where the name partition starts.operatorOffset
- offset for the operator partition.operatorLen
- length of the operator partition.operatorLine
- the line in the original document where the operator partition starts.operatorCol
- the column in the original document where the operator partition starts.valueContentOffset
- offset for the valueContent partition.valueContentLen
- length of the valueContent partition.valueOuterOffset
- offset for the valueOuter partition.valueOuterLen
- length of the valueOuter partition.valueLine
- the line in the original document where the value (outer) partition starts.valueCol
- the column in the original document where the value (outer) partition starts.- Throws:
ParseException
- if any exceptions occur during handling.
-
handleInnerWhiteSpace
public void handleInnerWhiteSpace(char[] buffer, int offset, int len, int line, int col) throws ParseException
Description copied from interface:IAttributeSequenceHandler
Called when an amount of white space is found inside an element.
This attribute separators can contain any amount of whitespace, including line feeds:
<div id="main" class="basic_column">
[INNWSP]
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.
- Specified by:
handleInnerWhiteSpace
in interfaceIAttributeSequenceHandler
- Overrides:
handleInnerWhiteSpace
in classAbstractMarkupHandler
- Parameters:
buffer
- the document buffer (not copied)offset
- offset for the artifact.len
- length of the artifact.line
- the line in the original document where the artifact starts.col
- the column in the original document where the artifact starts.- Throws:
ParseException
- if any exceptions occur during handling.

handleProcessingInstruction
public void handleProcessingInstruction(char[] buffer, int targetOffset, int targetLen, int targetLine, int targetCol, int contentOffset, int contentLen, int contentLine, int contentCol, int outerOffset, int outerLen, int line, int col) throws ParseException
Description copied from interface:IProcessingInstructionHandler
Called when a Processing Instruction is found.
Three [offset, len] pairs are provided for three partitions (outer, target and content):
<?xls-stylesheet somePar1="a" somePar2="b"?>
| [TARGET------] [CONTENT----------------] |
[OUTER-------------------------------------]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.
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.
- Specified by:

- Parameters:

- the document buffer (not copied)targetOffset
- offset for the target partition.targetLen
- length of the target partition.targetLine
- the line in the original document where the target partition starts.targetCol

- offset for the content partition.contentLen
- length of the content partition.contentLine
- the line in the original document where the content partition starts.contentCol
