[JDEV] Re: JabberCOM .OnMessage 'Tag' Parameter help

[David Banes]

Hi Peter,

Thanks, I'm using Delphi, what else :)

I've got a good handle on the IXMLTag and using iterators, what I'm not 
skilled up on is actually getting the interface from the Tag parameter. 
Preseumable I have to cast it, pass it or do something else to it as 
it's passed in as an OleVariant and I need it to be an IXMLTag. 

All I probably need (I hope) is a single line of code as an example as I 
exhauste the help and Delphi's 'help' on Interfaces and IDispatch.

Regards 

David.
