Binding energies of the $^3P_0$ and $^3P_2$ levels of the $1s^2\,2s\,2p$electron configuration in berylliumlike xenon are rigorously evaluated using abinitio QED approach. All relevant one- and many-electron QED contributions areaccounted for up to the second order of the perturbation theory. Theinterelectronic-interaction effects of the third and higher orders areconsidered within the Breit approximation. Nuclear recoil effect is taken intoaccount as well. In addition, we study all possible levels of the configuration$1s^2\,2s\,2p$, namely $^1P_1$ and $^3P_{0,1,2}$, by means of theconfiguration-interaction Dirac-Fock-Sturm method in berylliumlike neon, iron,and xenon. In this case the QED effects are treated approximately within themodel QED approach. The obtained theoretical predictions are compared with theresults of previous relativistic calculations and high-precision measurements.
