Method Detail

getRootNode

public org.w3c.dom.Node getRootNode()

Get the root node of the DOM being created. This is either a Document or a DocumentFragment.

getWriter

public java.io.Writer getWriter()

Return null since there is no Writer for this class.

setDocumentLocator

public void setDocumentLocator(org.xml.sax.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 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.

Specified by:

setDocumentLocator in interface org.xml.sax.DocumentHandler

Parameters:

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

See Also:

Locator

startDocument

public void startDocument()
                   throws org.xml.sax.SAXException

Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

Specified by:

startDocument in interface org.xml.sax.DocumentHandler

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException

Receive notification of the end of a document.

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 org.xml.sax.DocumentHandler

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

startElement

public void startElement(java.lang.String name,
                         org.xml.sax.AttributeList atts)
                  throws org.xml.sax.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.

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.

Specified by:

startElement in interface org.xml.sax.DocumentHandler

Parameters:

name - The element type name.

atts - The attributes attached to the element, if any.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

endElement(java.lang.String), AttributeList

endElement

public void endElement(java.lang.String name)
                throws org.xml.sax.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).

If the element name has a namespace prefix, the prefix will still be attached to the name.

Specified by:

endElement in interface org.xml.sax.DocumentHandler

Parameters:

name - The element type name

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws org.xml.sax.SAXException

Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data 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.

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

Specified by:

characters in interface org.xml.sax.DocumentHandler

Parameters:

ch - The characters from the XML document.

start - The start position in the array.

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

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

ignorableWhitespace(char[], int, int), Locator

charactersRaw

public void charactersRaw(char[] ch,
                          int start,
                          int length)
                   throws org.xml.sax.SAXException

If available, when the disable-output-escaping attribute is used, output raw text without escaping. A PI will be inserted in front of the node with the name "lotusxsl-next-is-raw" and a value of "formatter-to-dom".

startEntity

public void startEntity(java.lang.String name)
                 throws org.xml.sax.SAXException

Report the beginning of an entity. The start and end of the document entity are not reported. The start and end of the external DTD subset are reported using the pseudo-name "[dtd]". All other events must be properly nested within start/end entity events.

Specified by:

startEntity in interface org.xml.sax.ext.LexicalHandler

Parameters:

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

Throws:

org.xml.sax.SAXException - The application may raise an exception.

endEntity(java.lang.String), org.xml.sax.misc.DeclHandler#internalEntityDecl, org.xml.sax.misc.DeclHandler#externalEntityDecl

endEntity

public void endEntity(java.lang.String name)
               throws org.xml.sax.SAXException

Report the end of an entity.

Specified by:

endEntity in interface org.xml.sax.ext.LexicalHandler

Parameters:

name - The name of the entity that is ending.

Throws:

org.xml.sax.SAXException - The application may raise an exception.

See Also:

startEntity(java.lang.String)

entityReference

public void entityReference(java.lang.String name)
                     throws org.xml.sax.SAXException

Receive notivication of a entityReference.

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,
                                int length)
                         throws org.xml.sax.SAXException

Receive notification of ignorable whitespace in element content.

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.

Specified by:

ignorableWhitespace in interface org.xml.sax.DocumentHandler

Parameters:

ch - The characters from the XML document.

start - The start position in the array.

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

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

characters(char[], int, int)

processingInstruction

public void processingInstruction(java.lang.String target,

                           throws org.xml.sax.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 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.

Specified by:

processingInstruction in interface org.xml.sax.DocumentHandler

Parameters:

                  int length)
           throws org.xml.sax.SAXException

Receive notification of cdata.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data 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.
