Here is pure bash/ksh93 solution. Not used any external commands like awk, perl, grep, sed, ...
If you have too old bash, update it. Older bash parser has bug (ex. 4.1) , it can't parse correctly subprocess case syntax.
Code:
while read line
do
# grep using case
case "$line" in
\<jvmEntries*) ;;
*) continue ;;
esac
# sed using builtin properties
line=${line// =/=}
line=${line//= /=}
# parse line elements to the array using delimiter $IFS
elem=($line)
# create var=value lines and source it
. /dev/stdin <<< $(
for e in ${elem[@]}
do
# grep only xxx=xxx and xxx="xxx" values
case "$e" in
-*) continue ;;
*:*=*) continue ;; #
*=\"*\") ;; # set value
*=\"*) continue ;; #
*=*) ;; # set value ...
*) continue ;; # something else
esac
# this was interesting element, take it
echo "$e"
done
)
# show the variables
echo "initialHeapSize $initialHeapSize"
echo "maximumHeapSize $maximumHeapSize"
done < some.xml

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
