How to interpret a string as a multiline cell of expressions

Question

I need a string like the following:

"2+2
\"Hello
world\"
3+3"

to be evaluate like

2+2
"Hello 
world"
3+3

Note that ToExpression evaluates that string as

2+2;
"Hello 
world";
3+3

that is that it prints only the last line.

Answer 1

If I understand your question correctly, the following code

str = "2+2
\"Hello
world\"
3+3";
ToExpression[str, InputForm, Print /@ List[##] &];

does what you want. Alternatively, you can use

ToExpression[str, InputForm, List]

and decide what to do with the list later. The documentation for ToExpression states:

ToExpression[input, form, h]

wraps the head h around the expression produced before evaluating it.
