How to recursively delete objects - amazon-web-services

Question

I would like to delete all .JPEG files from specified path at S3 bucket. For example, lets say that I have structure on S3 cloud service similar to following:
Obj1/
Obj2/
Obj3/
image_1.jpeg
...
image_N.jpeg
Is it possible to specify Obj1/Obj2/Obj3 as DeleteObjectsInput's prefix and recursively delete all .JPEG files that contain such prefix.
Here is my code:
func (s3Obj S3) Delete() error {
sess := session.Must(session.NewSession(&aws.Config{
Region: aws.String(s3Obj.Region),
}))
svc := s3.New(sess)
input := &s3.DeleteObjectsInput{
Bucket: aws.String(s3Obj.Bucket),
Delete: &s3.Delete{
Objects: []*s3.ObjectIdentifier{
{
Key: aws.String(s3Obj.ItemPath),
},
},
Quiet: aws.Bool(false),
},
}
result, err := svc.DeleteObjects(input)
if err != nil {
if aerr, ok := err.(awserr.Error); ok {
switch aerr.Code() {
default:
glog.Errorf("Error occurred while trying to delete object from S3. Error message - %v", aerr.Error())
}
} else {
glog.Errorf("Error occurred while trying to delete object from S3. Error message - %v", err.Error())
}
return err
}
glog.Info(result)
return nil
}
sObj3.ItemPath represents Obj1/Obj2/Obj3 path from example above. As a result of this function I do not get any error. I actually get the following message:
Deleted: [{
Key: "Obj1/Obj2/Obj3"
}]
But when I check my S3 cloud service, nothing is done. What am I doing wrong?
EDIT
I've changed my code so my Delete function accepts list of objects from which I make a list of s3.ObjectIdentifier. There is roughly 50 .JPEG files in that list, and for some reason following code ONLY DELETES LAST ONE. I am not sure why.
func (s3Obj S3) Delete(objects []string) error {
sess := session.Must(session.NewSession(&aws.Config{
Region: aws.String(s3Obj.Region),
}))
svc := s3.New(sess)
var objKeys = make([]*s3.ObjectIdentifier, len(objects))
for i, v := range objects {
glog.Info("About to delete: ", v)
objKeys[i] = &s3.ObjectIdentifier{
Key: &v,
}
}
input := &s3.DeleteObjectsInput{
Bucket: aws.String(s3Obj.Bucket),
Delete: &s3.Delete{
Objects: objKeys,
Quiet: aws.Bool(false),
},
}
result, err := svc.DeleteObjects(input)
if err != nil {
if aerr, ok := err.(awserr.Error); ok {
switch aerr.Code() {
default:
glog.Errorf("Error occurred while trying to delete object from S3. Error message - %v", aerr.Error())
}
} else {
glog.Errorf("Error occurred while trying to delete object from S3. Error message - %v", err.Error())
}
return err
}
glog.Info(result)
return nil
}
