How to delete a worksheet if it doesn't exist in a list

Hi

I have a spreadsheet that creates a seperate worksheet for every item in a list, I want to then be able to change this list of data so that if I delete a line of data out of the list I could run a seperate macro that looks at the existing worksheets and deletes any that is not on that list.

Is this possible?

Due to the Data I am trying to analyse it is impossible for me to post this to a public forum, if you have any ideas on how this could be done if you could post an example of code I will happily interpret it... I would need to create a mock up outside of the work environment however...
