public void attributeDecl(String eName,
                          String aName,
                          String type,
                          String mode,
                          String value)
            throws SAXException

Report an attribute type declaration.

Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", a parenthesized token group with the separator "|" and all whitespace removed, or the word "NOTATION" followed by a space followed by a parenthesized token group with all whitespace removed.

The value will be the value as reported to applications, appropriately normalized and with entity and character references expanded.

Specified by:

attributeDecl in interface DeclHandler

Parameters:

eName - The name of the associated element.

aName - The name of the attribute.

type - A string representing the attribute type.

mode - A string representing the attribute defaulting mode ("#IMPLIED", "#REQUIRED", or "#FIXED") or null if none of these applies.

value - A string representing the attribute's default value, or null if there is none.

Throws:

SAXException - The application may raise an exception.

public void elementDecl(String name,
                        String model)
            throws SAXException

Report an element type declaration.

The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all parameter entities are fully resolved and all whitespace is removed,and will include the enclosing parentheses. Other normalization (such as removing redundant parentheses or simplifying occurrence indicators) is at the discretion of the parser.

Specified by:

elementDecl in interface DeclHandler

Parameters:

name - The element type name.

model - The content model as a normalized string.

Throws:

SAXException - The application may raise an exception.

public void endCDATA()
            throws SAXException

Report the end of a CDATA section.

Specified by:

endCDATA in interface LexicalHandler

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.startCDATA()

public void endDTD()
            throws SAXException

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(String,String,String)

public void endDocument()
            throws SAXException

Receive notification of the end of a document.

There is an apparent contradiction between the documentation for this method and the documentation for ErrorHandler.fatalError(SAXParseException). Until this ambiguity is resolved in a future major release, clients should make no assumptions about whether endDocument() will or will not be invoked when the parser has reported a fatalError() or thrown an exception.

The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

Specified by:

endDocument in interface ContentHandler

Throws:

SAXException - any SAX exception, possibly wrapping another exception

See Also:

ContentHandler.startDocument()

public void endElement(String uri,
                       String localName,
                       String qName)
            throws SAXException

Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement event for every endElement event (even when the element is empty).

For information on the names, see startElement.

Specified by:

endElement in interface ContentHandler

Parameters:

uri - the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed

localName - the local name (without prefix), or the empty string if Namespace processing is not being performed

qName - the qualified XML name (with prefix), or the empty string if qualified names are not available

Throws:

SAXException - any SAX exception, possibly wrapping another exception

public void endEntity(String name)
            throws SAXException

Report the end of an entity.

Specified by:

endEntity in interface LexicalHandler

Parameters:

name - The name of the entity that is ending.

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.startEntity(String)

public void endPrefixMapping(String prefix)
            throws SAXException

End the scope of a prefix-URI mapping.

See startPrefixMapping for details. These events will always occur immediately after the corresponding endElement event, but the order of endPrefixMapping events is not otherwise guaranteed.

Specified by:

endPrefixMapping in interface ContentHandler

Parameters:

prefix - the prefix that was being mapped. This is the empty string when a default mapping scope ends.

Throws:

SAXException - the client may throw an exception during processing

See Also:

ContentHandler.startPrefixMapping(String,String), ContentHandler.endElement(String,String,String)

public void externalEntityDecl(String name,
                               String publicId,
                               String systemId)
            throws SAXException

Report a parsed external entity declaration.

Only the effective (first) declaration for each entity will be reported.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

Specified by:

externalEntityDecl in interface DeclHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%'.

publicId - The entity's public identifier, or null if none was given.

systemId - The entity's system identifier.

Throws:

SAXException - The application may raise an exception.

public void ignorableWhitespace(char[] c,
                                int off,
                                int len)
            throws SAXException

public void internalEntityDecl(String name,
                               String value)
            throws SAXException

Report an internal entity declaration.

Only the effective (first) declaration for each entity will be reported. All parameter entities in the value will be expanded, but general entities will not.

Specified by:

internalEntityDecl in interface DeclHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%'.

value - The replacement text of the entity.

Throws:

SAXException - The application may raise an exception.

public void notationDecl(String name,
                         String publicId,
                         String systemId)
            throws SAXException

Receive notification of a notation declaration event.

It is up to the application to record the notation for later reference, if necessary; notations may appear as attribute values and in unparsed entity declarations, and are sometime used with processing instruction target names.

At least one of publicId and systemId must be non-null. If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application through this event.

There is no guarantee that the notation declaration will be reported before any unparsed entities that use it.

Specified by:

notationDecl in interface DTDHandler

Parameters:

name - The notation name.

publicId - The notation's public identifier, or null if none was given.

systemId - The notation's system identifier, or null if none was given.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

DTDHandler.unparsedEntityDecl(String,String,String,String), Attributes

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

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.

Like characters(), processing instruction data may have characters that need more than one char value.

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

public void setDocumentLocator(Locator locator)

Receive an object for locating the origin of SAX document events.

SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the ContentHandler interface.

The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.

Note that the locator will return correct information only during the invocation SAX event callbacks after startDocument returns and before endDocument is called. The application should not attempt to use it at any other time.

Specified by:

setDocumentLocator in interface ContentHandler

Parameters:

locator - an object that can return the location of any SAX document event

See Also:

Locator

public void setNamespaceAware(boolean namespaceAware)

public void setReader(XMLReader reader)

public void skippedEntity(String name)
            throws SAXException

Receive notification of a skipped entity. This is not called for entity references within markup constructs such as element start tags or markup declarations. (The XML recommendation requires reporting skipped external entities. SAX also reports internal entity expansion/non-expansion, except within markup constructs.)

The Parser will invoke this method each time the entity is skipped. Non-validating processors may skip entities if they have not seen the declarations (because, for example, the entity was declared in an external DTD subset). All processors may skip external entities, depending on the values of the http://xml.org/sax/features/external-general-entities and the http://xml.org/sax/features/external-parameter-entities properties.

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]"

Throws:

SAXException - any SAX exception, possibly wrapping another exception

public void startCDATA()
            throws SAXException

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

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.endCDATA()

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

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. (Note that this is not resolved against the document base URI.)

Throws:

SAXException - The application may raise an exception.

See Also:

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

public void startDocument()
            throws SAXException

Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other event callbacks (except for setDocumentLocator).

Specified by:

startDocument in interface ContentHandler

Throws:

SAXException - any SAX exception, possibly wrapping another exception

See Also:

ContentHandler.endDocument()

public void startElement(String uri,
                         String localName,
                         String qName,
                         Attributes atts)
            throws SAXException

Receive notification of the beginning of an element.

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:

1. the Namespace URI;
2. the local name; and
3. the qualified (prefixed) name.

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:

• the Namespace URI and local name are required when the namespaces property is true (the default), and are optional when the namespaces property is false (if one is specified, both must be);
• the qualified name is required when the namespace-prefixes property is true, and is optional when the namespace-prefixes property is false (the default).

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.

Specified by:

startElement in interface ContentHandler

Parameters:

uri - the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed

localName - the local name (without prefix), or the empty string if Namespace processing is not being performed

qName - the qualified name (with prefix), or the empty string if qualified names are not available

atts - the attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. The value of this object after startElement returns is undefined

Throws:

SAXException - any SAX exception, possibly wrapping another exception

See Also:

ContentHandler.endElement(String,String,String), Attributes, AttributesImpl

public void startEntity(String name)
            throws SAXException

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 report LexicalHandler events may not implement 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]".

Throws:

SAXException - The application may raise an exception.

See Also:

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

public void startPrefixMapping(String prefix,
                               String uri)
            throws SAXException

Begin the scope of a prefix-URI Namespace mapping.

The information from this event is not necessary for normal Namespace processing: the SAX XML reader will automatically replace prefixes for element and attribute names when the http://xml.org/sax/features/namespaces feature is true (the default).

There are cases, however, when applications need to use prefixes in character data or in attribute values, where they cannot safely be expanded automatically; the start/endPrefixMapping event supplies the information to the application to expand prefixes in those contexts itself, if necessary.

Note that start/endPrefixMapping events are not guaranteed to be properly nested relative to each other: all startPrefixMapping events will occur immediately before the corresponding startElement event, and all endPrefixMapping events will occur immediately after the corresponding endElement event, but their order is not otherwise guaranteed.

There should never be start/endPrefixMapping events for the "xml" prefix, since it is predeclared and immutable.

Specified by:

startPrefixMapping in interface ContentHandler

Parameters:

prefix - the Namespace prefix being declared. An empty string is used for the default element namespace, which has no prefix.

uri - the Namespace URI the prefix is mapped to

Throws:

SAXException - the client may throw an exception during processing

ContentHandler.endPrefixMapping(String), ContentHandler.startElement(String,String,String,Attributes)

public void unparsedEntityDecl(String name,
                               String publicId,
                               String systemId,
                               String notationName)
            throws SAXException

Receive notification of an unparsed entity declaration event.

Note that the notation name corresponds to a notation reported by the notationDecl event. It is up to the application to record the entity for later reference, if necessary; unparsed entities may appear as attribute values.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

Specified by:

unparsedEntityDecl in interface DTDHandler

Parameters:

name - The unparsed entity's name.

publicId - The entity's public identifier, or null if none was given.

systemId - The entity's system identifier.

notationName - The name of the associated notation.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.
