public class Parser

extends java.lang.Object

implements uk.co.weft.domutil.DocumentGenerator

Command line for ISO 8211 parse. TODO: Currently no real exception handling. This class (and consequently any class inheriting from this class) knows about the following tokens in contexts:

debug

Boolean: whether or not to print output to the output stream. Config only. Optional. Defaults to false.

doctype

The document type definition for the generated XML. Optional. No default. Note that there probably will be a default value in a later version.

dom_implementation_class

String: The name of the dom implementation to use. Optional. Defaults to org.apache.xerces.dom.DOMImplementationImpl. Note that the DOM implementation specified must be on the classpath.

root_name

String: the name of the root element of the generated XML. Context only. Optional. Defaults to iso8211.

s57_file_name

String: The relative path name of the S57 file to be parsed. Context only. Optional, but if not supplied s57_file_url must be. No default.

s57_file_url

String: The URL from which the S57 file to be parsed may be fetched. Context only. Optional, but if not supplied s57_file_name must be. If both are supplied s57_file_name is preferred. No default.

transform_url

String: the url of an XSL-T file which should be used to transform the output before printing. Config only. Optional. Defaults to null.

xmlns

String: the XML namespace specifier to use. Optional. No default. Note that there probably will be a default value in a later version.

However when running this parser from the command line both config and context tokens can be supplied as command line flags prefixed by '-'. The token to which the '-' is prepended will be used as a key in the context and the token following will be used as its value. Any token not either a keyword token (prepended with '-') or immediately following a key token on the command line will be taken as the name of an S57 file to be parsed, as though a '-s57_file_name' had been read. If multiple S57 input files are specified on the command line only the last will be read.

  Revision 1.3  2002/11/04 14:11:15  simon
  Now generating (some) XML. Tidy up for first public release.

  Revision 1.2  2002/11/02 00:09:16  simon
  Promising, but still not there. Problems include not correctly finding
  the start of the next record.

  Revision 1.1.1.1  2002/10/29 11:27:33  simon
  More or less parses
