java.lang.Objectcom.icl.saxon.output.Emitter
com.nwalsh.saxon.LineCountEmitter
Saxon extension to count the lines in a result tree fragment.
$Id: LineCountEmitter.java,v 1.1 2001/07/16 21:23:57 nwalsh Exp $
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.
Change Log:
Initial release.
Verbatim
