Look at the text2pcap program in the wireshark distribution as an example.

You could also use text2pcap. If you can write a program to convert
your XML to a text-file hex-dump, then you can execute text2pcap to
convert that to a pcap file.

I can export the data out of proprietary file to a XML-file. Wireshark doesn`t understand that format so I have the 3 options posted at the wireshark wiki (PacketInput). Because of my limited time, I think it will be the best way if  I´ll choose the way to convert the XML-file to a file which wireshark understands (libpcap). But I do not understand how to convert it, I mean how do I add the global header etc? I will convert it from XML file to *.txt file and then?
