- public class XmlDocumentFormat
- extends TextualDocumentFormat
The format of Documents. Subclasses of DocumentFormat know about
particular MIME types and how to unpack the information in any
markup or formatting they contain into GATE annotations. Each MIME
type has its own subclass of DocumentFormat, e.g. XmlDocumentFormat,
RtfDocumentFormat, MpegDocumentFormat. These classes register themselves
with a static index residing here when they are constructed. Static
getDocumentFormat methods can then be used to get the appropriate
format class for a particular document.

XmlDocumentFormat
public XmlDocumentFormat()
- Default construction
supportsRepositioning
public Boolean supportsRepositioning()
- We could collect repositioning information during XML parsing
- Overrides:
supportsRepositioning
in class DocumentFormat
unpackMarkup
public void unpackMarkup(Document doc)
throws DocumentFormatException
- Old style of unpackMarkup (without collecting of RepositioningInfo)
- Overrides:
unpackMarkup
in class TextualDocumentFormat
DocumentFormatException
unpackMarkup
public void unpackMarkup(Document doc,
RepositioningInfo repInfo,
RepositioningInfo ampCodingInfo)
throws DocumentFormatException
- Unpack the markup in the document. This converts markup from the
native format (e.g. XML) into annotations in GATE format.
Uses the markupElementsMap to determine which elements to convert, and
what annotation type names to use. If the document was created from a
String, then is recomandable to set the doc's sourceUrl to null.
So, if the document has a valid URL, then the parser will try to
parse the XML document pointed by the URL.If the URL is not valid, or
is null, then the doc's content will be parsed. If the doc's content is
not a valid XML then the parser might crash.
