removing certain paragraphs for matching patterns
Hi,
I have a log file which might have certain paragraphs.
Switch not possible Error code 1234
Process number 678
Log not available Error code 567
Process number 874
.....
......
......
Now I create an exception file like this.
cat text.exp
Error code 1234
Process number 874
What I want is to read my original file but exclude any paragraphs that might contact the keywords written in the exception file. How can I do that?

dancer::error
Dancer::Error(3pm) User Contributed Perl Documentation Dancer::Error(3pm)
NAME
Dancer::Error - class for representing fatal errors
SYNOPSIS
# taken from send_file:
use Dancer::Error;
my $error = Dancer::Error->new(
code => 404,
message => "No such file: `$path'"
);
Dancer::Response->set($error->render);
DESCRIPTION
With Dancer::Error you can throw reasonable-looking errors to the user instead of crashing the application and filling up the logs.
This is usually used in debugging environments, and it's what Dancer uses as well under debugging to catch errors and show them on screen.
ATTRIBUTES
code
The code that caused the error.
This is only an attribute getter, you'll have to set it at "new".
title
The title of the error page.
This is only an attribute getter, you'll have to set it at "new".
message
The message of the error page.
This is only an attribute getter, you'll have to set it at "new".
exception
The exception that caused the error. If the error was not caused by an exception, returns undef. Exceptions are usually objects that
inherits of Dancer::Exception.
This is only an attribute getter, you'll have to set it at "new".
METHODS
/SUBROUTINES
new
Create a new Dancer::Error object.
title
The title of the error page.
type
What type of error this is.
code
The code that caused the error.
message
The message that will appear to the user.
exception
The exception that will be useable by the rendering.
backtrace
Create a backtrace of the code where the error is caused.
This method tries to find out where the error appeared according to the actual error message (using the "message" attribute) and tries to
parse it (supporting the regular/default Perl warning or error pattern and the Devel::SimpleTrace output) and then returns an error-
higlighted "message".
tabulate
Small subroutine to help output nicer.
dumper
This uses Data::Dumper to create nice content output with a few predefined options.
render
Renders a response using Dancer::Response.
environment
A main function to render environment information: the caller (using "get_caller"), the settings and environment (using "dumper") and more.
get_caller
Creates a strack trace of callers.
_censor
An internal method that tries to censor out content which should be protected.
"dumper" calls this method to censor things like passwords and such.
_html_encode
Internal method to encode entities that are illegal in (X)HTML. We output as UTF-8, so no need to encode all non-ASCII characters or use a
module. FIXME : this is not true anymore, output can be any charset. Need fixing.
