If you are still looking for all the object tags rather than VI tags consider the examples below as it is LV version agnostic (or at least agnostic since the VI file format standard this tool supports). One thing to note is the method mentioned above assumes printable characters are in the tag name.
Using the low level VI manipulation vi explorer from here https://github.com/flarn2006/VILab is a good way to see this. I think you are better off keying off "Tag Name" since tag names technically don't have to be printable ASCII.
See example snip where DEADBEEF in hex would not be printable.
