public class LineCountEmitter

extends com.icl.saxon.output.Emitter

Saxon extension to count the lines in a result tree fragment.

Copyright (C) 2000 Norman Walsh.

This class provides a Saxon 6.* implementation to count the number of lines in a result tree fragment.

The general design is this: the stylesheets construct a result tree fragment for some verbatim environment. That result tree fragment is "replayed" through the LineCountEmitter; the LineCountEmitter watches characters go by and counts the number of line feeds that it sees. That number is then returned.
