var v interface{}
if err := yaml.UnmarshalWithOptions(b, &v, yaml.UseOrderedMap()); err != nil {
	log.Fatal(err)
}

q := query.New(
	query.CaseInsensitive(),
	query.CustomExtractFunc(yamlextractor.MapSliceExtractFunc()),
).Index(0).Key("FOO")
got, err := q.Extract(v)
if err != nil {
	log.Fatal(err)
}
fmt.Println(got)
