Double Quotations: escape character for xml?

I’m pretty new to xml concept. Anyway I was playing around with xml/flash and thought of use the double quotations with escape character to see the effect something like this xml file: example="blah blah blah “blah” and example=‘blah blah blah’s blah’ but Flash seem doesn’t support the escape method. Is there any method that flash/xml will support the escape character?
