Something like 

lynx -source http://domain.com/report.php?id=22|grep -v ^$|sendmail-i -t

should work shouldn't it. Since it's HTML any other blank lines can be
removed also. I tested it with this
cat /etc/samba/smb.conf|grep -v ^$

I use the command
cat /etc/samba/smb.conf|grep -v ^$|grep -v ^#
to clean up config files before I share them with others.
