Reduce the number of lines in script

Hello All,

I have created a script which will show the errors from a log file in between a particular section.

Code:
v1=$(sed -n "/Main Report/,/Main Report End/p" input | grep -i 'Unable to find'
v2=$(sed -n "/Main Report/,/Main Report End/p" input | grep -i 'Unable to add'

if [ -z "$v1" ]
then
echo "All report deployed properly"
else
echo "List of report failed to deploy in Main Report due to Null pointer exception"
echo "$v1"
fi 

if [ -z "v2"]
then
echo "All Report Deployed Properly"
else
echo "List of report failed to deploy in Main Report due to xml issue"
echo "$v"
fi 

v3=$(sed -n "/Second Report/,/Second Report End/p" input | grep -i 'Unable to find'
v4=$(sed -n "/Second Report/,/Second Report End/p" input | grep -i 'Unable to add'

if [ -z "$v3" ]
then
echo "All report deployed properly"
else
echo "List of report failed to deploy in Second Report due to Null pointer exception"
echo "$v3"
fi 

if [ -z "v4"]
then
echo "All Report Deployed Properly"
else
echo "List of report failed to deploy in Second Report due to xml issue"
echo "$v4"
fi

Is there a way I can use some loop to reduce these code lines. The error are same but in different part of logs.

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
atf-sh(3) BSD
