Keep it simple:

Pipe your html screen into this perl script
(Or modify the script to read in the lines itself)
Note - this relys on your html file ALWAYS having the above format.


==============CUT HERE =========================
#!/usr/bin/perl


while (<STDIN>)  {
        if  ( /Estimated Pages Remaining:/ ) {

#	Read in five more line and print out the fifth one.

                $_=<STDIN> ;
                $_=<STDIN> ;
                $_=<STDIN> ;
                $_=<STDIN> ;
                $_=<STDIN> ;
		print "here it is: ";
                print $_ ;
        }
}
==============CUT HERE =========================

Uncompiled, untested, unwarranteed. etc .. Use at your own Risk,
FWIW, IANAL , IMHO   blah blah blah.
