Wireshark-dev: [Wireshark-dev] Call XML and JSON dissectors with new HTTP Content-Type

Hi all,

Web Integration Service (http://www.omg.org/spec/DDS-WEB/1.0/Beta2/) is a new service that sends/receives DDS traffic (RTPS) over HTTP. The serialization is not directly RTPS but a conversion handled internally, that can be XML or JSON.

I would like to add support to show the content of the HTTP packets as it is done for XML. The Content-Type is "application/dds-web+xml". If I change it to "application/xml" internally, it works sweet.

How can I make Wireshark apply the XML dissector when receiving "application/dds-web+xml"? I have been inspecting the code but I want some advice since this is an important dissector.

I will implement this for myself, and once it is stable and I make sure it doesn't change, I will push the changes to the community.

Also, knowing how to implement the equivalent for JSON would be awesome.

Thanks,
Juanjo Martin
