java.lang.Object | +--org.xml.sax.HandlerBase | +--gate.xml.XmlDocumentHandler
Implements the behaviour of the XML reader Methods of an object of this class are called by the SAX parser when events will appear. The idea is to parse the XML document and construct Gate annotations objects. This class also will replace the content of the Gate document with a new one containing anly text from the XML document.

Method Summary | |
void |
addStatusListener(StatusListener listener)
This methos is called when a listener is registered with this class |
void |
characters(char[] text,
int start,
int length)
This method is called when the SAX parser encounts text in the XML doc. |
void |
comment(String text)
This method is called when the SAX parser encounts a comment It works only if the XmlDocumentHandler implements a com.sun.parser.LexicalEventListener |
void |
endCDATA()
This method is called when the SAX parser encounts the end of a CDATA section. |
void |
endDocument()
This method is called when the SAX parser encounts the end of the XML document. |
void |
endElement(String elemName)
This method is called when the SAX parser encounts the end of an XML element. |
void |
endParsedEntity(String name,
boolean included)
This method is called when the SAX parser encounts a parsed entity and informs the application if that entity was parsed or not It's working only if the CustomDocumentHandler implements a com.sun.parser.LexicalEventListener |
void |
error(org.xml.sax.SAXParseException ex)
Error method.We deal with this exception inside SimpleErrorHandler class |
void |
fatalError(org.xml.sax.SAXParseException ex)
FatalError method. |
protected void |
fireStatusChangedEvent(String text)
This methos is called whenever we need to inform the listener about an event. |
void |
ignorableWhitespace(char[] ch,
int start,
int length)
This method is called when the SAX parser encounts white spaces |
void |
removeStatusListener(StatusListener listener)
This methos is called when a listener is removed |
void |
startCDATA()
This method is called when the SAX parser encounts a start of a CDATA section It works only if the XmlDocumentHandler implements a com.sun.parser.LexicalEventListener |
void |
startDocument()
This method is called when the SAX parser encounts the beginning of the XML document. |
void |
startElement(String elemName,
org.xml.sax.AttributeList atts)
This method is called when the SAX parser encounts the beginning of an XML element. |
void |
