Wireshark · Wireshark-dev: Re: [Wireshark-dev] XML Dissection in Wireshark

[Sachin Gupta <sachgupta@xxxxxxxxx>]

Hi,

I made a Generic Wireshark Plugin which parses the XML protocol files and dissect the protocol packets, but due to some legal reasons I was not able to release it to Wireshark. 

You can define XML tags to define the protocols and the fields, use some XML to C++ parser (like I used tiny xml parser) and then

make a plugin which will read a specific directory for all the XML files at startup and make parsers for the protocols.

regards

Sachin

Hi,

1. Make sure that the XML dissector preferences are set correctly.
2. Look in the dtds subdirectory where the installed DTD's are stored.
   Use them as examples. Add your DTD here and start Wireshark to
   get it to load.

Thanks,
Jaap
