[Webtest] Waitfor a regexp result (not supported?)

[Roberto Corda]

Hi all,

I want to write a script like this (pseudo-code)

START

<wait for>
  <regexp text="<something>"  result="value"/>
  <available "#{value}" />
</wait>

END

In other terms I want to repeat regexp until something is found. I think that 
this feature is not supported. Do you have any suggest in which part webtest 
program I have to analize?

Thanks i nadvance R.
