How to remove content present in between specific pattern ?

Hi,

I have a file with following pattern. We are looking to filter out only specific content from this file.

Code:
 
sample
 
BLAdmins    Server.*
LinuxAdmins    Server.*
Policy Name: Recommended Default ACL Policy
Everyone    ACLPushJob.Read
Everyone    ACLTemplate.Read
Everyone    AuditJob.Read 
 
End of Policy: Recommended Default ACL Policy
 
Policy Name: Admin ACL Policy
BLAdmins    ACLPushJob.Read
BLAdmins    ACLTemplate.Read
BLAdmins    AuditJob.Read 
 
End of Policy: Admin ACL Policy

We wish to write content from sample file to another file by removing everything in between "Policy Name:" and "End of Policy:".

so the expected output will be as below

Code:
 
new_sample
BLAdmins    Server.*
LinuxAdmins    Server.*



Regards,
Litu

NAME
Perl::Critic::Policy::ControlStructures::ProhibitUntilBlocks - Write "while(! $condition)" instead of "until($condition)". AFFILIATION
This Policy is part of the core Perl::Critic distribution. DESCRIPTION
Conway discourages using "until" because it leads to double-negatives that are hard to understand. Instead, reverse the logic and use "while". until($condition) { do_something() } #not ok until(! $no_flag) { do_something() } #really bad while( ! $condition) { do_something() } #ok This Policy only covers the block-form of "until". For the postfix variety, see "ProhibitPostfixControls". CONFIGURATION
This Policy is not configurable except for the standard options. SEE ALSO
