#!/usr/bin/perl
$inString=qq(<tr>	<td valign=top width=194><font class=s2 
face="Arial,Helvetica"
size=2>Total Sheets Fed</font></td>
	<td valign=top width=130><font class=s2 face="Arial,Helvetica"
 size=2>59986</font></td>
);

($totalSheets)=($inString =~ /<td.*Total Sheets Fed.*?>(\d+)</s);

print("Total sheets = '$totalSheets'\n");


Of course, if the only 130-wide column is total sheets fed, then you can use 
the more robust

($totalSheets)=($inString =~ /<td valign=top width=130><font class=s2 
face="Arial,Helvetica"
 size=2>(\d+)</s);
