[xml] xmlCopyProp

[Uwe Fechner <uwe fechner 4commerce de>]

Hello Daniel,

the current version of xmlCopyProp (from the cvs) doesn't work.

It crashes, if called with null as target.

(I passed a property without parent and without namespace.
The same, if I called it with a property with parent
and without namespace.)

Could you have a look at it, please?

Best regards:

Uwe
