RecTV/2/key=Animation

RecTV/2/key=Animation/0 => All animation

RecTV/2/key=Animation/1

Family Guy The Simpsons

RecTV/2/key=Animation/1/key=Family Guy/0 all Family Guy which are an animation

RecTV/4/key=101/2/key=Comedy/0 All comedy on channel 101 ... ...

BTW, it seems unneeded to declare ProcessRoot?, ProcessAll?, ProcessItem?, ProcessKey?, ProcessContainer? in class UPnpCDSExtensionResults as virtual as they are never user in child class

Due to the sub grouping I have only 3 case: processAvailableGroup (title, genre ...) processGroup (genre=Animation ...) processResult which return a list of recordings

In fact, ProcessItem? is needed but the other are very specific to the organization of the upnp extension and we can not generalize Xavier

[Xavier Hervy <xavier.hervy@…>]

No change apart for coding convention and update description on top of the cpp file

This patch does not take care of utf8 yet and might not work if a key contain a / I will send a new patch later one

[robertm]

Xavier, you mentioned a patch to fix the UTF-8 and slash-escaping 19 months ago, still working on this?

[robertm]

Closing as stale, Xavier, if you still have interest and want to work through the issues you mentioned above, please feel free to reopen this ticket with a new patch and I will do my best to corral someone to look at it.
