DIESEL - String Extraction

[Martin Schmid]

I have a string variable that will either be atomic, i.e.: XXX Or it will have 3 values, separated by spaces: XXX YYY ZZZ The lengths are not constant.

Can I use diesel to evaluate if there are spaces, have it extract the 1st, 2nd, or 3rd value, or if it is atomic, just return the value?

Thanks,
MS
