  We present splitting functions in the triple collinear limit at
next-to-leading order. The computation was performed in the context of massless
QCD+QED, considering only processes which include at least one photon. Through
the comparison of the IR divergent structure of splitting amplitudes with the
expected known behavior, we were able to check our results. Besides that we
implemented some consistency checks based on symmetry arguments and
cross-checked the results among them. Studying photon-started processes, we
obtained very compact results.
