Hi, I don't know if this is any more efficient than the method you're using, but... I've attached a workspace that uses a Grepper with the expression ^([^S]*)(.*)$ to split out the first part of the string from the symbol code then does a ListExploder to generate the individual features. There are a couple intermediate steps to clean up the text list before doing the ListExploder.
There are a few cases where features get dropped by the ListExploder, but as long as each feature entering this workspace has at least two items (ID and SYMBOL) in the list, you should be OK. Note for Safe: This would be a lot easier there was a ListPopper transformer (from either end). Not sure how this would work with multi-attribute lists though.

I was to output everything but the last element of a list. The last element of the list will differ from the other elements in that it will always begin with S e.g. 3102, 3128, S013 Length of the list will vary. Here's a bit more detail. I have (Irish) ntf data with point data with an attribute feature_code_list. Basically this same as UK ntf data but points and lines are not represented on multiple layers so this needs to be handled. Let's say for example the value of this feature_code_list attribute for one point is 3102, 3128, S013 I want to output 2 point features Associating the symbol information S013 with each point. The attribute beginning with S is the symbol information. It will always be the last element in the list. I can do this for a list of 3 elements in a convoluted manner using a tester to compute length of lists etc. What I've been doing in the is computing the length of the list getting the index number of the last element of the list: length of list -1 and using a tester to compute if the length of the list > 2 and the index number is >=2 Instead of hardcoding the value 2 I can using a value based on the length of the feature list so that the method will work where the FEATURE_CODE_LIST attribute contains more or less than 3 pieces of information. There should be a better way to do this. Will the above method impact on performace? Here are my ideas: Would using a grepper transformer to check if the list attribute contains a character S? I tried using Attribute Classifier but don't think integer will do the trick. Or what is the best method to use the listexploder, exploding everything but the last element of the list? Any thoughts would be appreciated. Thanks A Get the maximum benefit from your FME, FME Objects, or SpatialDirect via our Professional Services team. Visit www.safe.com/services for details. Yahoo!
