Copy part of a rich text to another document

Hi!I have a rich text item like this

1w .- 23/01/2005 → TEXT

5t .- 23/07/2004 → TEXT → DOCLINK

2x .- 24/01/2003 → TEXT

4r .- 22/01/2002 → TEXT → DOCLINK

7a .- 21/01/2002 → TEXT → DOCLINK

I need to find everything that is created before year 2002 and copy to another document. Not every line have a doclink, because of this i need to find the date 22/01/2002 (in this example) and copy everythis after this.

I hope you understand me and i´m sorry for my english

Thanks
