OK, I never noticed there are two sections. Any way to dump only one?

My initial goal was to find a specific pattern in the RR cache. This
seems to work, thanks for the help:
findincache() {
if [ -z "$1" ]; then
echo "Usage: findincache PATTERN"
return 1
fi
pat="$1"
TMP=$(mktemp -d)
cur="$(pwd)"
cd "$TMP"
sudo unbound-control dump_cache | csplit - /END_RRSET_CACHE/ > /dev/null
egrep "$pat" xx00
cd "$cur"
rm -rf $TMP
}
% findincache nlnetlabs |head -n 2
nlnetlabs.nl. 10149 IN NS ns.nlnetlabs.nl.
nlnetlabs.nl. 10149 IN NS sec2.authdns.ripe.net.
% findincache 'renater\.fr\.\s+[0-9]+\s+IN\s+AAAA'
ns1.renater.fr. 15 IN AAAA 2001:660:3001:4002::2
ns2.renater.fr. 15 IN AAAA 2001:660:3001:4002::9
