Monks,

I've got a multi-line text file in the format: 

"@QUERY:FOO"
...data...
...data...
...etc...
"@ENDQUERY"
"@QUERY:BAR"
...data...
...data...
...etc...
"@ENDQUERY"

I want to go line-by-line through the file, and grab the data in between @QUERY and @ENDQUERY and do stuff to it (namely put it in a HoH).

Here's the code block in question: 

while (<FH>) {
    if ($_ =~ /^\"\@QUERY:(.*)\"/) {
        my $query = $1;
        my $i = 1;
        while (<FH> !~ /^\"\@ENDQUERY\"/) {
            print $_;
            #$data{$query}->{$i}->{$_} unless ($_ eq "");
            $i++;
        }
    }
}

My question: why is $_ not getting the next line of FH in the 2nd while loop? The print statement I have there prints the first pattern matched (e.g. @QUERY:FOO, @QUERY:BAR) for each line of data enclosed by @QUERY/@ENDQUERY until it reaches @ENDQUERY.

Thanks for any help,

AH
