how to extract whole xml structure from soap envelope using tshark?

edit

I am using following command: tshark.exe -r test.pcap -T fields -Y xml -e frame.number -e xml.tag -e xml.cdata -E separator=@ > out.txt

but this gives me all xml tags and cdata but not in xml structure. I want whole xml structure. is there any work around??

Any help would be highly appreciated.

Thanks you
