Search for a text between two strings in a file using regex

Here is my sample file data:

Quote:
##
## SSL Virtual Host Context

SSLInsecureRenegotiation Off

Seconds before invalid OCSP responses are expired from the cache

<VirtualHost _default_:443>
SSLInsecureRenegotiation Off
RewriteOptions Inherit
SSLInsecureRenegotiation Off
RewriteOptions Inherit

# General setup for the virtual host
DocumentRoot "/web/htdocs"
ServerName www.example.com:443
ServerAdmin you@example.com
ErrorLog "|/web/bin/rotatelogs /web/logs/sslerror_log.%Y-%m-%d 86400 combined"
TransferLog "/web/logs/access_log"

# SSL Engine Switch:
SSLEngine on

SSLCertificateFile "/web/conf/server.crt"

# ECC keys, when in use, can also be configured in parallel
<FilesMatch "\.(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory "/web/cgi-bin">
AllowOverrideList None

# SSLInsecureRenegotiation Off

</Directory>

CustomLog "/web/logs/ssl_request_log" \
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

SSLInsecureRenegotiation On
# BEGIN ANSIBLE MANAGED BLOCK
<FilesMatch "^.*\.(css|html?|js|pdf|txt|xml|xsl|gif|ico|jpe?g|png)$">
Require all granted
</FilesMatch>
# END ANSIBLE MANAGED BLOCK
</VirtualHost>
My requirement is to have a regex expression that is able to search for visible starting string "SSLInsecureRenegotiation Off" between strings "<VirtualHost " and "</VirtualHost>".

In the sample data two lines should be matched.

Below is what I tried but it does not match the two lines within the Virtual Tags.

Code:
(?<=<VirtualHost ).*^[^#]*SSLInsecureRenegotiation.*Off.*(?=</VirtualHost>)

Can you please suggest how ?

Mason::Manual::Setup(3pm)				User Contributed Perl Documentation				 Mason::Manual::Setup(3pm)

NAME
Mason::Manual::Setup - Setting up Mason SETUP
Web development The most common use of Mason is to generate dynamic web content. Poet is a web framework designed specifically to work with Mason. Given an HTTP request, Poet generates a corresponding Mason request, and uses the output from Mason to form the HTTP response. Poet takes care of the web development details that are outside of Mason's domain, such as server integration and configuration. Poet::Manual::Tutorial shows how to set up a Poet/Mason site in great detail. Mason can also be used in the popular web frameworks Catalyst and Dancer, as a drop-in replacement for their default template engines. See Catalyst::View::Mason2 and Dancer::Template::Mason2. Non-web development Mason can be used to generate any kind of dynamic content. I have personally used it to generate Apache configuration files, emails, and C++ code. To use Mason from a script or library, use the Mason::Interp API: my $interp = Mason->new( comp_root => '/path/to/comps', data_dir => '/path/to/data', ... ); my $output = $interp->run( '/request/path', foo => 5 )->output(); If you want to process a directory with a mix of Mason templates and static files, check out Any::Template::ProcessDir. To try out Mason syntax from the command line, use the mason script: % mason 2 + 2 = <% 2+2 %> ^D 2 + 2 = 4 LOGGING
Mason uses Log::Any to log various events, such as the start and end of each request. You can direct thesse logs to the output of your choice; see Log::Any::Adapter. If you don't specify anything then the logs will go into the void. SEE ALSO
