protected boolean extract()
                   throws ExtractionException

Description copied from class: MicroformatExtractor

Performs the extraction of the data and writes them to the model. The nodes generated in the model can have any name or implicit label but if possible they SHOULD have names (either URIs or AnonId) that are uniquely derivable from their position in the DOM tree, so that multiple extractors can merge information.

Specified by:

extract in class MicroformatExtractor

Returns:

true if extraction is successful

Throws:

ExtractionException - if there is an error during extraction
