Is there any better way to dump data? (http)

I'm using tshark to get html pages out of a capture file, and checking how many of those contain a specific element. Currently I'm using the following params:

tshark.exe -r test.pcap -o "tcp.desegment_tcp_streams:TRUE"  -R "tcp.stream==13 and http" -T pdml > test.session13.pdml

and get the html documents themselves inside a data-text-lines element spread over many field elements in the output pdml. Which means that I need to concatenate the data in those elements to get the whole html back together. That's not a great problem, I just wonder, is there a better way to do so? Meaning, letting tshark itself output the complete html?

thanks!
