        Parameters:
        systemID - the system ID of the data source
        lineNr - the line on which the parsing starts
        Throws:
        Exception - If an exception occurred while processing the event.

        newProcessingInstruction in interface IXMLBuilder
        Parameters:
        target - the PI target
        reader - to read the data from the PI
        Throws:
        Exception - If an exception occurred while processing the event.
      • startElement

        public void startElement​(String name,
                                 String nsPrefix,

                                 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,

        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,

                              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.

        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:

        Returns:
        the result of the building process.
        Throws:
