  We propose an exotic scenario that topological superconductivity can emerge
by doping strongly interacting fermionic systems whose spin degrees of freedom
form bosonic symmetry protected topological (SPT) state. Specifically, we study
a 1-dimensional (1D) example where the spin degrees of freedom form a spin-1
Haldane phase. {Before doping, the charge and spin degrees of freedom are both
gapped.} Upon doping, {the charge channel becomes gapless and is described by a
$c=1$ compactified bosonic conformal field theory (CFT), while the spin channel
remains gapped and still form a bosonic SPT state. Interestingly,} an
instability toward $p$-wave topological superconductivity is induced coexisting
with the symmetry protected spin edge modes that are inherited from the Haldane
phase. This scenario is confirmed by density-matrix renormalization group
simulation of a concrete lattice model, where we find that topological
superconductivity is robust against interactions. We further show that by
stacking doped Haldane phases an exotic 2D anisotropic superconductor can be
realized, {where the boundaries transverse to the {chain-}direction are either
gapless or spontaneously symmetry-broken due to the Lieb-Schultz-Mattis (LSM)
anomaly.}
