Как правильно проитерировать ноды в yq?

source_data() {
cat<<EOF
- name1: "some_name1_text"
  some1_1: "some1_1_text1"
  some1_2: "some1_2_text2"
- some_node2: "some_node2_1_text"
  some2_1: "some2_1_text1"
  some2_2: "some2_2_text2" 
- xxx: "xxx_text"
  some2_1: "some2_1_text1"
  some2_2: "some2_2_text2" 
EOF
} 

parse() {
  local index=0
  while source_data | yq ".[$index]" -e > /dev/null 2>&1; do
    echo "Item $index:"
    source_data | yq ".[$index]"
    ((index++))
  done
}

source_data | yq | parse
