Class XMLtemplate2HTML

java.lang.Object
  com.infoengine.xml.XMLtemplate2HTML

All Implemented Interfaces:

DocumentHandler, DTDHandler, ErrorHandler, I_handleXML

public class XMLtemplate2HTML

extends Object

implements I_handleXML

Event handler class for converting I*E 2.x XML templates into I*E 2.x HTML templates.

This handler will convert the XML webject tags into appropriate HTML-based equivalents, allowing the SA I*E 2.x server to remain ignorant of XML.

Method Summary

void	characters(char[] ch, int start, int length) This method is called for data imbedded between tags; we'll use it for catching some of the template parameters.
private static void	display(char[] ch, int start, int length) Display text, escaping some characters.
void	endDocument() This method will be called when the SAX parser has completed it's parsing of the passed XML document.
void	endElement(String name) This method will be called for the end of each XML element encountered; for XML->HTML Template conversion, this is used to handle the tagging.
void	error(SAXParseException exception) Report all recoverable errors, and try to continue parsing.
void	fatalError(SAXParseException exception) Report all fatal errors, and try to continue parsing.
int	getErrorLevel()
String	getOutput()
void	ignorableWhitespace(char[] ch, int start, int length) Not used by I*E.
void	notationDecl(String name, String publicId, String systemId) Display notation declarations as they are reported.
void	processingInstruction(String target, String data) Print a message for a processing instruction.
void	setDocumentLocator(Locator locator) Print a message when the parser provides a locator.
void	startDocument() This method will be called when the SAX parser has begun parsing the document; this would be good time to open an output stream and other setup tasks.
void	startElement(String name, AttributeList attributes) This method is called for the start of each XML element encountered; we need to check said element against a list of possible conversion choices, and then write to the output stream said conversion.
void	unparsedEntityDecl(String name, String publicId, String systemId, String notationName) Display unparsed entity declarations as they are reported.
void	warning(SAXParseException exception) Report all warnings, and continue parsing.

Method Detail

getOutput

public String getOutput()

Specified by:

getOutput in interface I_handleXML

getErrorLevel

public int getErrorLevel()

Specified by:

getErrorLevel in interface I_handleXML

notationDecl

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

Display notation declarations as they are reported.

Specified by:

notationDecl in interface DTDHandler

See Also:

DTDHandler.notationDecl(java.lang.String, java.lang.String, java.lang.String)

unparsedEntityDecl

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

Display unparsed entity declarations as they are reported.

Specified by:

unparsedEntityDecl in interface DTDHandler

See Also:

DTDHandler.unparsedEntityDecl(java.lang.String, java.lang.String, java.lang.String, java.lang.String)

setDocumentLocator

public void setDocumentLocator(Locator locator)

Print a message when the parser provides a locator.

Not all SAX parsers will provide a locator object.

Specified by:

setDocumentLocator in interface DocumentHandler

See Also:

DocumentHandler.setDocumentLocator(org.xml.sax.Locator)

startDocument

public void startDocument()

This method will be called when the SAX parser has begun parsing the document; this would be good time to open an output stream and other setup tasks.

Specified by:

startDocument in interface DocumentHandler

See Also:

DocumentHandler.startDocument()

endDocument

public void endDocument()

This method will be called when the SAX parser has completed it's parsing of the passed XML document. When this method is called, we can finish rendering of the HTML template.

Specified by:

endDocument in interface DocumentHandler

See Also:

DocumentHandler.endDocument()

startElement

public void startElement(String name,
                         AttributeList attributes)

This method is called for the start of each XML element encountered; we need to check said element against a list of possible conversion choices, and then write to the output stream said conversion. A rather pedestrian bit of String processing code. *shrug* It's a living...

Specified by:

startElement in interface DocumentHandler

See Also:

DocumentHandler.startElement(java.lang.String, org.xml.sax.AttributeList)

endElement

public void endElement(String name)

This method will be called for the end of each XML element encountered; for XML->HTML Template conversion, this is used to handle the tagging.

Specified by:

endElement in interface DocumentHandler

See Also:

DocumentHandler.endElement(java.lang.String)

characters

public void characters(char[] ch,
                       int start,
                       int length)

This method is called for data imbedded between tags; we'll use it for catching some of the template parameters.

Specified by:

characters in interface DocumentHandler

See Also:

DocumentHandler.characters(char[], int, int)

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,
                                int length)

Not used by I*E.

Specified by:

ignorableWhitespace in interface DocumentHandler

See Also:

DocumentHandler.ignorableWhitespace(char[], int, int)

processingInstruction

public void processingInstruction(String target,
                                  String data)

Print a message for a processing instruction.

Specified by:

processingInstruction in interface DocumentHandler

See Also:

DocumentHandler.processingInstruction(java.lang.String, java.lang.String)

warning

public void warning(SAXParseException exception)

Report all warnings, and continue parsing.

Specified by:

warning in interface ErrorHandler

See Also:

ErrorHandler.warning(org.xml.sax.SAXParseException)

error

public void error(SAXParseException exception)

Report all recoverable errors, and try to continue parsing.

Specified by:

error in interface ErrorHandler

See Also:

ErrorHandler.error(org.xml.sax.SAXParseException)

fatalError

public void fatalError(SAXParseException exception)

Report all fatal errors, and try to continue parsing.

Note: results are no longer reliable once a fatal error has been reported.

Specified by:

fatalError in interface ErrorHandler

See Also:

ErrorHandler.fatalError(org.xml.sax.SAXParseException)

display

private static void display(char[] ch,
                            int start,
                            int length)
