case statement in chameleon zpt

[george hu]

Hi, I'm wondering how can I write a switch/case block like bellow:

<tal:block tal:switch="x">

   <tal:case="0 or 1"> 

      <div> ..... </div>

   <tal:case="2">

      <div> ....</div>

</tal:block>

it seems that  case doesn't support logic operator (and /or /not)here. So, is there any way I can do it in the switch?

Thanks

(0 or 1) evaluates to 1, so if x == 0 you won't get a hit.

If you must use switch here I think you're going to have to repeat yourself:

<div tal:switch='x'>

  <p tal:case='0'>zero or one</p>

  <p tal:case='1'>zero or one</p>

  <p tal:case='2'>two</p>

</div>

Or you could use tal:condition --

<div>

  <p tal:condition='x in (0,1)'>zero or one</p>

  <p tal:condition='x == 2'>two</p>

</div>

Can I use x in (0,1) in tal:condition, coz I think the switch is more concise here.
