parse

public void parse(java.io.InputStream stream,
                  org.xml.sax.ContentHandler handler,
                  Metadata metadata,
                  ParseContext context)
           throws org.xml.sax.SAXException

Description copied from interface: Parser

Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

org.xml.sax.SAXException - if the SAX events could not be processed
