You are pushing multiple references to the same hash. You need to create a new hash for each page. A small change that does that is to change

    if($data =~ /^page$/)   {
                push(@pagesArray,\%hash);
    }
[download]

to:

    if($data =~ /^page$/)   {
        push @pagesArray, {%hash};
        %hash = ();
    }
[download]

which simply creates a copy of the hash.
