public void setDocumentLocator(Locator locator)
DocumentHandler
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 DocumentHandler 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 of the events in this interface. The application should not attempt to use it at any other time.
setDocumentLocator
in interface DocumentHandler
org.xml.sax.DocumentHandler
locator
- An object that can return the location of
any SAX document event.Locator
public void startDocument()
DocumentHandler
The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

org.xml.sax.DocumentHandler
SAXException
- Any SAX exception, possibly
wrapping another exception.public void endDocument() throws SAXException
DocumentHandler
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.

SAXException
- Any SAX exception, possibly
wrapping another exception.public void doctype(java.lang.String name, java.lang.String publicID, java.lang.String systemID)
public void ignorableWhitespace(char[] ch, int start, int length)
DocumentHandler
Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.
SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.
The application must not attempt to read from the array outside of the specified range.
ignorableWhitespace
in interface DocumentHandler
org.xml.sax.DocumentHandler
ch
- The characters from the XML document.start

public void processingInstruction(java.lang.String target, java.lang.String data)
DocumentHandler
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 should 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.
processingInstruction
in interface DocumentHandler
org.xml.sax.DocumentHandler

- The processing instruction target.data
- The processing instruction data, or null if
none was supplied.SAXException
- Any SAX exception, possibly

EntityResolver
The Parser will call this method before opening any external entity except the top-level document entity (including the external DTD subset, external entities referenced within the DTD, and external entities referenced within the document element): the application may request that the parser resolve the entity itself, that it use an alternative URI, or that it use an entirely different input source.
Application writers can use this method to redirect external system identifiers to secure and/or local URIs, to look up public identifiers in a catalogue, or to read an entity from a database or other input source (including, for example, a dialog box).
If the system identifier is a URL, the SAX parser must resolve it fully before reporting it to the application.

public void notationDecl(java.lang.String name, java.lang.String publicId, java.lang.String systemId)
DTDHandler
It is up to the application to record the notation for later reference, if necessary.
If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application.

public void unparsedEntityDecl(java.lang.String name, java.lang.String publicId, java.lang.String systemId, java.lang.String notationName)
DTDHandler
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.
If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

DocumentHandler
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.
If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).
