Need to assign value to a variable and export it at the same time
I have a file a.xml contaning:
<customerId>999</customerId>
<aaa>09876</aaa>
Now I want to extract the value '999' and save it in a variable and then export the variable. Something like the below:
export CUSTOMER_ID=cat a.xml |grep customerId |awk -F ">" '{print $2}' |awk -F "<" '{print $1}'
Whereas
cat a.xml |grep customerId |awk -F ">" '{print $2}' |awk -F "<" '{print $1}' is giving the expected result i.e. 999
But when I want to save it in a variable, it is not working

version::next
Version::Next(3pm) User Contributed Perl Documentation Version::Next(3pm)
NAME
Version::Next - increment module version numbers simply and correctly
VERSION
version 0.002
SYNOPSIS
use Version::Next;
my $new_version = next_version( $old_version );
DESCRIPTION
This module provides a simple, correct way to increment a Perl module version number. It does not attempt to guess what the original
version number author intended, it simply increments in the smallest possible fashion. Decimals are incremented like an odometer. Dotted
decimals are incremented piecewise and presented in a standardized way.
If more complex version manipulation is necessary, you may wish to consider Perl::Version.
USAGE
This module uses Sub::Exporter for optional exporting. Nothing is exported by default.
"next_version"
my $new_version = next_version( $old_version );
Given a string, this function make the smallest logical increment and returns it. The input string is very minimally checked that it
resembles a version number. Given "undef", the function returns 0.
Decimal versions are incremented like an odometer, preserving the original number of decimal places. If an underscore is present
(indicating an "alpha" version), its relative position is preserved. Examples:
0.001 -> 0.002
0.999 -> 1.000
0.1229 -> 0.1230
0.12_34 -> 0.12_35
0.12_99 -> 0.13_00
Dotted-decimal versions have the least significant element incremented by one. If the result exceeds 999, the element resets to 0 and the
next most significant element is incremented, and so on. Any leading zero padding is removed. Examples:
v1.2.3 -> v1.2.4
v1.2.999 -> v1.3.0
v1.999.999 -> v2.0.0
v1.2.3_4 -> v1.2.3_5
v1.2.3_999 -> v1.2.4_0
