yet another interpretation of your question... You want to go through a file and if you find a word, reparse the whole file or the second part of the file? Perhaps this could help.

my @file = <FILE>;   #all the contents of the file are
                     # now in @file, one line per element
my @toppart;
my @bottompart;
while(@file)
{
       $_ = shift @file;
       push(@toppart, $_), next unless /PAGE:    2/;

                     # this is reached after the match
       @bottompart =  ($_, @file);
       last;
}

# at this point @toppart has all the lines from the file
# that were above the first occurance of /Page:    2/
# @bottompart has the first matching line and the rest of
# the file.
# @file has the same as @bottompart without the matching  
# line.  Obviously if you don't want the matching line
# you don't need @bottompart.
