Delete a group of Dicom tags at once

Question

I have a dicom sequence that contains several “Item” (fffe,e000).

Each item contains two tags (300a,004a) & (300a,00b8)

One of the tags (type string -has a value of “xyz”) I want to remove belongs inside the "item" group

I would like to delete entire "item".

This is what I have tried so far

//look for specific string e.g. “xyz”

  for(int i = 0; i < count; i++)

{

    if(tagName == "xyz")

{

//tag found , now remove complete item ()

 var remove = DicomTag.Parse("300a,004a");

 openedDicom.Dataset.Remove(remove);

openedDicom.Save(Path.Combine(dirPath, "Test.dcm"));

}}

Is there a better way to do this rather than one at a time, basically remove complete Item, only the correct item?
