                         String systemID,
                         int lineNr)
                  throws Exception

This method is called when a new XML element is encountered.

Specified by:

startElement in interface IXMLBuilder

Parameters:

name - the name of the element

nsPrefix - the prefix used to identify the namespace

nsSystemId - the system ID associated with the namespace

systemID - the system ID of the data source

lineNr - the line in the source where the element starts

Throws:

Exception - If an exception occurred while processing the event.

addAttribute

public void addAttribute(String key,
                         String nsPrefix,

This method is called when a new attribute of an XML element is encountered.

Specified by:

addAttribute in interface IXMLBuilder

Parameters:

key - the key (name) of the attribute

nsPrefix - the prefix used to identify the namespace

nsSystemId - the system ID associated with the namespace

value - the value of the attribute

type - the type of the attribute ("CDATA" if unknown)

Throws:

addPCData

public void addPCData(Reader reader,
                      String systemID,
                      int lineNr)
               throws Exception

This method is called when a PCDATA element is encountered. A Java reader is supplied from which you can read the data. The reader will only read the data of the element. You don't need to check for boundaries. If you don't read the full element, the rest of the data is skipped. You also don't have to care about entities; they are resolved by the parser.

Specified by:

addPCData in interface IXMLBuilder

Parameters:

reader - the Java reader from which you can retrieve the data

systemID - the system ID of the data source

lineNr - the line in the source where the element starts

Throws:

IOException - when the reader throws such exception

Exception - If an exception occurred while processing the event.

getResult

public Object getResult()
                 throws Exception

Returns the result of the building process. This method is called just before the parse() method of IXMLParser returns.

Specified by:

getResult in interface IXMLBuilder

Returns:

the result of the building process.

Throws:

Exception - If an exception occurred while processing the event.

IXMLParser.parse()

endDocument

public void endDocument()
                 throws Exception

Indicates that parsing has been completed.

Throws:

Exception
