If the arrowhead always consists of two lines shorter than the shaft, an easy way is to calculate length of all the lines with LengthCalculator, sort them by length descending with Sorter, and select the first one for each identical ID with Sampler or DulicateFilter.

i have tested before but I have still no luck .
Bcs some of them is connected as arrow head and line (as one object )
so if I want to calculate the length ,it calculate for the whole line with arrowahead .they are not seperated .
