I’m not hard coding the string, I’m reading it from an XML. So, whatever I do, I need to do it by manipulating the string.

E.g. if the string I read contains

Foo "Bar” Foo

your suggestion means  I have to programmatically change that to

Foo \quotation{Bar} Foo

which is too complicated, given that I don’t have regular expression replace at my disposal.

I might be able to change al “ instances into something else by walking through the string and building a new one.
