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

pvm_export
EXPORT(3PVM) EXPORT(3PVM)
NAME
pvm_export, pvm_unexport - Mark environment variables to export through spawn
SYNOPSIS
C int cc = pvm_export( char *name )
int cc = pvm_unexport( char *name )
Fortran Not available
PARAMETERS
name Name of an environment variable to add to or delete from export list.
DESCRIPTION
The routines pvm_export and pvm_unexport are provided for convenience in editing environment variable PVM_EXPORT, while maintaining the
colon-separated list syntax it requires. The variable can be modified by other means, and at the same time by the pvm_export functions.
pvm_export checks to see if a name is already in PVM_EXPORT before including it, and exporting a name more than once is not considered an
error. Likewise, pvm_unexport will not complain if you specify a name not in PVM_EXPORT.
EXAMPLES
C:
/* PVM_EXPORT=SHELL:HOME */
pvm_export("DISPLAY");
pvm_export("TERM");
pvm_unexport("HOME");
/* PVM_EXPORT=SHELL:DISPLAY:TERM */
ERRORS
No error conditions are currently returned by pvm_export and pvm_unexport.
