will this have damaged the cat? - rip
I ran out of petrol (tried to start this morning and jerking) i got about half a mile before it could not start at all.

I put some petrol in, and reset the ecu by taking off the negative battery lead. car is xantia 1.8 16v

Will i have done any damage to the cat or any other components? its running back to normal now.

usually the cat only gets damaged if you have had some major backfiring going on but otherwise if it is running ok now it should be fine.

When the car runs low on petrol the mixture gets too weak to ignite properly and so you get 'misfiring'. Some unburned petrol therefore reaches the cat and actually oxidises in the cat. This is harmful to the cat. Realistically though, you are unlikely to have damaged it - they can usually stand a bit of minor mistreatment and 1/2 mile of misfiring shouldn't have harmed it.
