Halogen solution are great oxidising agents right? But when you dissolve halogens(chlorine, bromine) in water, ionic compounds are formed
Cl₂+h₂0  HOCL+HCL.
There aren't any chlorine molecules to act as oxidising agents since only HOCL and HCL present.I am quite confused by this. Thanks in advance

Cl₂+h₂0  HOCL+HCL

More precisely

Cl₂ + H₂O  HOCl + HCl

- this is an equilibrium reaction, so there is always some free chlorine available.

Besides, OCl^- is a strong oxidizing agent as well.

the reaction mentioned by you is a disproportionation reaction in which Cl2 is undergoing oxidation and reduction.Cl2 ----> HOCl is oxidation  and Cl2---> HCl is reduction.HCl is stable but HOCl has Cl in +1 oxidation state which is very unstable.It has very high tendency to undergo reduction and hence acts like very strong oxidizing agent.
