skippedEntity

public void skippedEntity(String name)

Receive notification of a skipped entity.

Specified by:

skippedEntity in interface ContentHandler

Parameters:

name - The name of the skipped entity. If it is a parameter entity, the name will begin with '%', and if it is the external DTD subset, it will be the string "[dtd]".

processingInstruction

public void processingInstruction(String target,
                                  String data)
                           throws SAXException

Description copied from interface: ContentHandler

Receive notification of a processing instruction.

The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

A SAX parser must never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

Specified by:

processingInstruction in interface ContentHandler

Parameters:

target - The processing instruction target.

data - The processing instruction data, or null if none was supplied. The data does not include any whitespace separating it from the target.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

startDTD

public void startDTD(String name,
                     String publicId,
                     String systemId)

Description copied from interface: LexicalHandler

Report the start of DTD declarations, if any.

This method is intended to report the beginning of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

All declarations reported through DTDHandler or DeclHandler events must appear between the startDTD and endDTD events. Declarations are assumed to belong to the internal DTD subset unless they appear between startEntity and endEntity events. Comments and processing instructions from the DTD should also be reported between the startDTD and endDTD events, in their original order of (logical) occurrence; they are not required to appear in their correct locations relative to DTDHandler or DeclHandler events, however.

Note that the start/endDTD events will appear within the start/endDocument events from ContentHandler and before the first startElement event.

Specified by:

startDTD in interface LexicalHandler

Parameters:

name - The document type name.

publicId - The declared public identifier for the external DTD subset, or null if none was declared.

systemId - The declared system identifier for the external DTD subset, or null if none was declared.

See Also:

LexicalHandler.endDTD(), LexicalHandler.startEntity(java.lang.String)

endDTD

public void endDTD()
            throws SAXException

Description copied from interface: LexicalHandler

Report the end of DTD declarations.

This method is intended to report the end of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

Specified by:

endDTD in interface LexicalHandler

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.startDTD(java.lang.String, java.lang.String, java.lang.String)

startEntity

public void startEntity(String name)

Description copied from interface: LexicalHandler

Report the beginning of some internal and external XML entities.

The reporting of parameter entities (including the external DTD subset) is optional, and SAX2 drivers that support LexicalHandler may not support it; you can use the http://xml.org/sax/features/lexical-handler/parameter-entities feature to query or control the reporting of parameter entities.

General entities are reported with their regular names, parameter entities have '%' prepended to their names, and the external DTD subset has the pseudo-entity name "[dtd]".

When a SAX2 driver is providing these events, all other events must be properly nested within start/end entity events. There is no additional requirement that events from DeclHandler or DTDHandler be properly ordered.

Note that skipped entities will be reported through the skippedEntity event, which is part of the ContentHandler interface.

Because of the streaming event model that SAX uses, some entity boundaries cannot be reported under any circumstances:

• general entities within attribute values
• parameter entities within declarations

These will be silently expanded, with no indication of where the original entity boundaries were.

Note also that the boundaries of character references (which are not really entities anyway) are not reported.

All start/endEntity events must be properly nested.

Specified by:

startEntity in interface LexicalHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%', and if it is the external DTD subset, it will be "[dtd]".

See Also:

LexicalHandler.endEntity(java.lang.String), DeclHandler.internalEntityDecl(java.lang.String, java.lang.String), DeclHandler.externalEntityDecl(java.lang.String, java.lang.String, java.lang.String)

endEntity

public void endEntity(String name)

Description copied from interface: LexicalHandler

Report the end of an entity.

Specified by:

endEntity in interface LexicalHandler

Parameters:

name - The name of the entity that is ending.

See Also:

LexicalHandler.startEntity(java.lang.String)

startCDATA

public void startCDATA()

Description copied from interface: LexicalHandler

Report the start of a CDATA section.

The contents of the CDATA section will be reported through the regular characters event; this event is intended only to report the boundary.

Specified by:

startCDATA in interface LexicalHandler

See Also:

LexicalHandler.endCDATA()

endCDATA

public void endCDATA()

Description copied from interface: LexicalHandler

Report the end of a CDATA section.

Specified by:

endCDATA in interface LexicalHandler

See Also:

LexicalHandler.startCDATA()

comment

public void comment(char[] ch,
                    int start,
                    int length)
             throws SAXException

Description copied from interface: LexicalHandler

Report an XML comment anywhere in the document.

This callback will be used for comments inside or outside the document element, including comments in the external DTD subset (if read). Comments in the DTD must be properly nested inside start/endDTD and start/endEntity events (if used).

Specified by:

comment in interface LexicalHandler

Parameters:

ch - An array holding the characters in the comment.

start - The starting position in the array.

length - The number of characters to use from the array.

Throws:

SAXException - The application may raise an exception.
