Is there WSDL support in the current version of wireshark? I have a problem that bit for me quite a while because the analyzer didn't decoded the WSDL/XML data. It is just displayed as TCP data generically. In the frame below, you can see 9080 in the HEX data and you can see that the decoding ends at the TCP layer by looking at the Detail data.
