  We propose a novel scheme for resolving the contribution of inner- and
outer-valence electrons in XUV-initiated high-harmonic generation in neon. By
probing the atom with a low energy (below the 2s ionisation threshold)
ultrashort XUV pulse, the 2p electron is steered away from the core, while the
2s electron is enabled to describe recollision trajectories. By selectively
suppressing the 2p recollision trajectories we can resolve the contribution of
the 2s electron to the high-harmonic spectrum. We apply the classical
trajectory model to account for the contribution of the 2s electron, which
allows for an intuitive understanding of the process.
