java.lang.Objectorg.xml.sax.helpers.DefaultHandler
gate.xml.XmlPositionCorrectionHandler
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 only text from the XML document.

XmlDocumentHandler.CustomObject
The objects belonging to this class are used inside the stack. |

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. |
