Fair point. Neither do I. But your next comment:

is not suitable, because it assumes that the substring "docs" appears 
only once in the string.

In a more realistic example, you don't know what the string contains, 
only that it is delimited by dots and that you want to replace the n-th
field (whatever it contains) with "wiki".
