Perl Regex matching multiple lines

I need a way to extract data from

Code:
X 4T  Solution 21 OCT 2011 37 .00
to account 12345678 User1 user2
X 4T  Solution  Solution Unlimited 11 Sep 2009 248 .00
to account 87654321 user3 user4

I need it to extract 'X' '37.00' and account number 12345678.

I have extracted above stuff from another data files and need to process on the result.

So what code I have is

Code:
if (/START OF STUFF/../End of Stuff/) 
{
   if  ( /^X/../\D+\w\s+20[0-9][0-9]\s\d\.\d\n\d+/ ) {
   print $_."\n";
   }
}

I can extract the complete lines But i need only the matching one
Any suggestions...

MU-EXTRACT(1)						      General Commands Manual						     MU-EXTRACT(1)

NAME
mu_extract - display and save message parts (attachments), and open them with other tools. SYNOPSIS
mu extract [options] <file> mu extract [options] <file> <pattern> DESCRIPTION
mu extact is the mu sub-command for extracting MIME-parts (e.g., attachments) from mail messages. It works on message files, and does not require the message to be indexed in the database. For attachments, the file name used when saving it, is the name of the attachment in the message. If there is no such name, or when saving non-attachment MIME-parts, a name is derived from the message-id of the message. If you specify a pattern (a case-insensitive regular expression) as the second argument, all attachments with filenames matching that pat- tern will be extracted. The regular expressions are Perl-compatible (as per the PCRE-library). Without any options, mu extract simply outputs the list of leaf MIME-parts in the message. Only 'leaf' MIME-parts (including RFC822 attach- ments) are considered, multipart/* etc. are ignored. OPTIONS
-a, --save-attachments save all MIME-parts that look like attachments. --save-all save all non-multipart MIME-parts. --parts=<parts> only consider the following numbered parts (comma-separated list).The numbers for the parts can be seen from running mu extract without any options but only the message file. --target-dir=<dir> save the parts in the target directory rather than the current working directory. --overwrite overwrite existing files with the same name; by default overwriting is not allowed. --play Try to 'play' (open) the attachment with the default application for the particular file type. On MacOS, this uses the open program, on other platforms is uses xdg-open. You can choose a different program by setting the MU_PLAY_PROGRAM environment variable. EXAMPLES
To display information about all the MIME-parts in a message file: $ mu extract msgfile To extract MIME-part 3 and 4 from this message, overwriting existing files with the same name: $ mu extract --parts=3,4 --overwrite msgfile To extract all files ending in '.jpg' (case-insensitive): $ mu extract msgfile '.*.jpg' To extract an mp3-file, and play it in the the default mp3-playing application. $ mu extract --play msgfile 'whoopsididitagain.mp3' BUGS
