Need to extract specific text from a big unstructured log file (Text File ) in Perl
===

I need to extract information from a text file (log file), the log file looks as below,

=========================================================================
**MIN**      : 8586519095               DN              : 8586519095
ESN      : fefad172                 Account Type    : enabled
MEID     : 00000000000000
MS Status: inactive                 Authen. Capable : n
-------------------------------------------------------------------------
Origination Type: international     Restrict Digits :
Termination Type: unrestricted      Roaming CoS     : 0
-------------------------------------------------------------------------

-------------------------------------------------------------------------
VLR Address
    MSC ID:
    Identification Number
        Nature of Address :         Numbering Plan  :
        Encoding Format   :         Address         :
    SSN:                            Point Code      :
    System Capability     :         TRANS Capability  :
    WIN Capability  :           **Last Access Time:**
-------------------------------------------------------------------------

I have to just extract the MIN field and Last access time field (recurrently) from the file, I have used Perl before to extract information on Large XML files using XML modules. Is there anything similar for Text files ? 

Thanks in advance for the help.
