Hello everybody,

I just have one tricky issue - how can FME detect attribute value, which is composed strictly by white spaces, e.g. ? Its not empty value in DB view, but it is hardly detected. Any idea please?

It doesnt matter on count of white spaces.

Thank You so much!

Lubo

Use a StringSearcher, select the attribute and the following parameters. Then you will have a list called _allWhitespaces with all the whitespaces together. So if the attribute has 3 whitespaces the list will consist of 3 elements
