I have a dataset with a large number of attributes I want to write to KML. Since most of the fields for any one record will be empty I'd like to check each field of each record and remove the field if it does not contain data. The search criteria for each field are the same so I'd like to loop the attributes from an array of some sort.
I've looked at lists and looping in custom transformers but I can't quite see a path.
Any suggestions would be greatly appreciated,
Alan

The nullattributereplacer would be the first I would try.
hope this helps
Thank you both for the tips.
Unfortunately the nullattributereplacer will only insert a value into an otherwise null attribute. It won't remove the attribute entirely.
The NullAttributeRemover will remove the attributes but many of my fields contain a value for "NULL" such as -999999. Those it will not remove. I'll see if I can further customize it to look for and remove such values.
Again, thanks to you both,
Alan
