[CWB] Empty XML tags not showing in CQP

[Javier Pueyo]

Thank you Stefan,

When I read your second suggestion I had a light-bulb moment and decided to
make "inf" an attribute of the "turn" tag (it is much better structurally
and now I can show "turn_inf"  in CQP, and hopefully visualize it in
CQPWeb):

-S turn+id+inf

CORPUS> show +turn_inf;
CORPUS> <turn> [word=".*"];

0:      <<turn_inf E>okay> ya son las horas ah

Unfortunately, I cannot apply the same solution to other empty tags I use
in my corpus (like <silence/>, <noise/>, etc), since they may appear in any
position within a given speech turn.

But being able to visualize "inf" was really important. Thanks for the clue!

Javier
