^ is the regex indicating the beginning of the line.

This will change the prefix from 'x' to 'test'. As far as I know, you can only change the prefix and not the suffix. So the split files will be testaa, testab and so on

Code:
sed -n /^D/p file | split -l2 - test

With logcheck-test you can easily write and test new rules.
