Object factory... Is that how it's called??

Hello,
I'm quite new to smalltalk, and I'm developping on Squeak. As part of my studies I must create a serializer, wich translates an object to a xml file, and vice versa.
My question is, how should I do to create an instance of, for example, a 'toto' class (yes, it is a String, readen from the xml file)??
If anyone can help me, it would be great! Thanks by advance!

PS: Mr Ducasse, c'est ma question bonus ça!

you should have a look at SIXX which is a XML serializer for squeak and
you'll probably find ideas in it...

otherwise maybe:
(Smalltalk at: 'toto' asSymbol ifAbsent:[^nil]) to get the class from a
String

SIXX provides a simple solution to serialise and deserialise XML
objects. Check the website.

Better yet:

Smalltalk classNamed: 'Toto'

(btw, regular class names are always capitalized)

(Smalltalk at: #Toto) new

Good but you need more than one question :)
But you saw these squeakers are nice and they already replied to you
without RTFM kinds of absurd and aggressive
behavior.

The deal was that if they ask questions on any squeaking mailing-list
they get more credits :)
