using (Metadata metadata = new Metadata(Constants.InputDocx))
{
// Remove all the properties satisfying the predicate:
// property contains the name of the document author OR
// it refers to the last editor OR
// the property value is a string that contains the substring "John" (to remove any mentions of John from the detected metadata)
var affected = metadata.RemoveProperties(
p => p.Tags.Contains(Tags.Person.Creator) ||
p.Tags.Contains(Tags.Person.Editor) ||
p.Value.Type == MetadataPropertyType.String && p.Value.ToString().Contains("John"));
