      ReplaceMarker

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class ReplaceMarker
extends org.xml.sax.helpers.DefaultHandler

This SAX parser processes the beginning of an XML corpus file and generates a copy replacing in mode 3 or 4 all orth elements with the replacements specified in a ConversionDictionary, otherwise stripping the elements or replacing them with strings of Xx chars changed parts are marked with HTML font color markup during the process

ReplaceMarker

public ReplaceMarker(java.lang.StringBuffer input,
                     java.lang.StringBuffer output,
                     int aMode,
                     java.lang.String theOrthPath,
                     java.lang.String thePosPath)

A Replacer needs two String buffers for original and preview data, a mode, and specification of the content to mask.

Parameters:

input - - a String buffer for constructing the HTML representation of the input data

output - - a String buffer for constructing the HTML representation of the preview data

aMode - - an integer between 0 and 4 for different modes (for internal use)

theOrthPath - - the XPath expression to define masked content

thePosPath - - the XPath expression to define classification of content for dictionary retrieval

log - - a Drop object to handle logging messages in the GUI - null for console output
