transformer to cut the value of an attribute

The AttributeSplitter is probably what you're looking for, it can take either a delimiter or a format string. A format string is what you'll need

Just to expand on the above as last time I looked it did not appear to be clearly documented.

If you have a 10 character string and you wanted to cut into 2 characters 4 characters 4 characters

in the format string box type 2s4s4s

The first 2 characters get stored in _list{0}, the first group of 4 in _list{1} and the second group of 4 in _list{2}

If you want to do this as the data is being read, I would suggest the CSV format reader (if there is a delimiter character between fields) or the CAT format reader (if the data is aligned to particular columns).

Have a look at the SubstringExtractor. It is doing exactly what you are describing.

Unfortunately there is no delimiter so I have to split these items on there fixed position in the attribute.

Because of the <spaces>* the outcome of the FormatString does not match the data anymore. Variating with the other parameters will do no good.

The list is represented as

So my best option for now seems to be the SubstringExtractor.

Thanks all for your imput.

Yes, I made a mistake in the FormatString, After correcting the AttributeSplitterParameter is works. Thnks all.
