increment numbering

I need some help... I have attribute text….the description of the text is this.

SD-X-L1-FACP5/Z1

DD-X-L1-FACP5/Z2

MCP-X-L1-FACP5/Z3

SF-X-L2-FACP5/Z5

Now what I need is to renumber it incrementally and it should goes like this.

SD-1-L1-FACP5/Z1

DD-2-L1-FACP5/Z2

MCP-3-L1-FACP5/Z3

SF-4-L2-FACP5/Z5

My problem is theres a lot of tagging like this one & It change every time, every day its very difficult to do it one by one so If I have a lisp that can be use in this situation it’s a big help for me.
