I have a text that looks like this. What I want to do is
- to extract the whole paragraph under the section "Aceview summary" until the line that starts with "Please quote".
- extract the line that starts with "The closest human gene".
And store them into array with two elements.
However I am stuck with the following script logic. What's the right way to achieve that?
#!/usr/bin/perl -w
my $INFILE_file_name = $file; # input file name
open ( INFILE, '<', $INFILE_file_name )
or croak "$0 : failed to open input file $INFILE_file_name : $!\n";
my @allsum;
while ( <INFILE> ) {
chomp;
my $line = $_;
my @temp1 = ();
if ( $line =~ /^ AceView summary/ ) {
print "$line\n";
push @temp1, $line;
}
elsif( $line =~ /Please quote/) {
push @allsum, [@temp1];
@temp1 = ();
}
}
close ( INFILE ); # close input file
