If I wanted to use sweep in particular, then I'd probably just let the OS get the path for me. I'd also set the not installed to a date, that way the EA can be set as a date format rather than having mixed responses. You can then do date is newer than....
#!/bin/bash
the_sweep=`which sweep`
if [ $? = 0 ]
then
get_release=`$the_sweep -v | awk -F ":" '/Released/ {print $NF}'`
result=`/bin/date -j -f " %d %b %Y" "${get_release}" "+%Y-%m-%d"`
else
result="1984-01-24"
fi
echo "<result>$result</result>"
exit 0
Otherwise as suggested by @stevewood it's just a case of running pretty much that line, surrounded by some error checking. Could use different hours:mins:secs or a different date to distinguish between the two alternative cases, instead of the same default date.
#!/bin/bash
default_date="1984-01-24"
if [ -e /Library/Sophos Anti-Virus/VDL/vvf.xmfl ]
then
result=`awk -F """ '/VirusData Version/ {print $(NF-1)}' /Library/Sophos Anti-Virus/VDL/vvf.xml`
if [ $? != 0 ]
then
result="$default_date"
fi
else
result="$default_date"
fi
echo "<result>$result</result>"
exit 0
I'm also a fan of bash rather than sh. Although they both report as being bash...
mymac:~ root# bash --version
GNU bash, version 3.2.53(1)-release (x86_64-apple-darwin13)

mymac:~ root# sh --version

..they aren't and bash has more to offer eg. sh can't do process substitution. Taking the above sophos as an example. Run this as sh and it will fail.
#!/bin/bash
the_sweep=`which sweep`
if [ $? = 0 ]
then
# Use process substitution to make variables available outside loop
while read line
do
case "$line" in
"Released"*)
result_date=`/bin/date -j -f " %d %b %Y" "${line##*:}" "+%Y-%m-%d"`
;;
"Virus data version"*)
result_version="${line##*:}"
;;
"Data file name"*)
break
;;
esac
done < <($the_sweep -v)
result="$result_date :$result_version"
else
result="Not installed"
fi
echo "<result>$result</result>"
sh scripts should be able to be run as bash, bash scripts may or may not be able to be run as sh.
