ShrkBite,
You beat me to it man. Instead of Aircraft Carrier, should have Zeppelins with aircraft attached (now let me go read to see if we can find any historical craft to seed this with)
I don't think any of the airships (rigid, semi-rigid or non-rigid) used by any country during WW1 were capable of launching planes from them. The first time a parasitic fighter was launched from an airship was in 1932 over New Jersey when USS Akron launced and recovered first in a N2Y trainer and then later in the Curtiss XF9C-1 Sparrowhawk, which was specifically designed as a parasitic fighter for use onboard 'flying aircraft carriers' that were to be used for recce/scout duties.
Here is a photo of the USS Akron that shows the 'trapeze' launching system and a Sparrowhawk in Akron's internal hanger.

Normally, the landing gear on the Sparrowhawk would have been removed for normal operations but in the above photo, the gears are still attached in case the pilot was unable to hook up on the trapeze and had to land at the base below during flight testing.
