Grep specific records from a file of records that are separated by an empty line

Hi everyone.

I am a newbie to Linux stuff. I have this kind of problem which couldn't solve alone. I have a text file with records separated by empty lines like this:
Code:
ID: 20
Name: X
Age: 19

ID: 21
Name: Z

ID: 22
Email: xxx@yahoo.com
Name: Y
Age: 19

I want to grep records that have both 'Email' and 'Age' like in the last one and put that record in another file. How to do that?

Thanks in advance
Atrisa

Email::Folder(3pm)					User Contributed Perl Documentation					Email::Folder(3pm)

NAME
Email::Folder - read all the messages from a folder as Email::Simple objects. SYNOPSIS
use Email::Folder; my $folder = Email::Folder->new("some_file"); print join " ", map { $_->header("Subject") } $folder->messages; METHODS
new($folder, %options) Takes the name of a folder, and a hash of options If a 'reader' option is passed in then that is used as the class to read in messages with. messages Returns a list containing all of the messages in the folder. Can only be called once as it drains the iterator. next_message acts as an iterator. reads the next message from a folder. returns false at the end of the folder bless_message($message) Takes a raw RFC822 message and blesses it into a class. By default this is an Email::Simple object but can easily be overriden in a subclass. For example, this simple subclass just returns the raw rfc822 messages, and exposes the speed of the parser. package Email::RawFolder; use base 'Email::Folder'; sub bless_message { $_[1] }; 1; reader read-only accessor to the underlying Email::Reader subclass instance PERL EMAIL PROJECT
