Populates a new list from a series of attributes. The attributes to be used are specified by the expression parameter. Each attribute's index in the list is specified by the order of the attribute in the sorted result of the regular expression.
See the StringSearcher for more information on regular expressions.
The geometry of each feature entering the transformer is not changed.
For example, if the expression parameter is set to "^bob", and a feature entered the transformer with the following attributes:
bob0 = 'cat'
bob1 = 'dog'
bob2 = 'rooster'
anotherAttr = 'carrot'
then, presuming that the list name specified was "somelist", the feature would now look like:
bob0 = 'cat'
bob1 = 'dog'
bob2 = 'rooster'
anotherAttr = 'carrot'
somelist{0} = 'cat'
somelist{1} = 'dog'
somelist{2} = 'rooster'
Parameters
Source Attribute Expression
Specify an attribute expression from which to form the list.
List Name
The name for the new list.
