[Zope] Delete quotes in strings

[Frank Zorge]

Hi,
Does anyone know how to delete quotes in strings, for instance delete the
quotes in: 'hello'. I tried to use string.replace but I don't get the syntax
right.
<dtml-call "REQUEST.set('var',_.string.replace(var,''',' ')">
Or maybe there's a better way?

Thanks
