Hi Nepomuk,
Thank you so much for your reply.
I am trying to connect to a UPNP device (dish VIP222) and set the channel to a channel I got from a MySQL data base to read the information generated by the UPNP device about that channel and store it into my database.
I have some XML code that can help me connect to the UPNP device and set the channel but I do not know how to use it on a C++ program which already had the part of...

I already downloaded the XSD for linux, XECERS-C,and EXPAT. I have the XML files and code and want to create a C++ code but I do not know and can not find out how to use the XSD tool in order to create the C++ code. Can any one tell me what do I need to do now.
Thank you so much
