Question

I’m trying to split all the words in a string into an array in AS3. The obvious answer of course would be to simply do this:

str.split(/\s/);

The problem here is that I need to be able to tell whether the split occurred on a newline or a space. I’m trying to put the words of a string into draggable boxes, and I want the ones after a newline to go, well, on a new line.

Any idea the best way to go about this? Clearly, the above split method will get rid of the crucial newline character that will tell me what I need to know. Should I use a regex.exec with a while loop, or is there any way to use split to preserve the characters I need?

Answer 1

Example string :

     This is an example string  
     with spaces as well as newlines 
     and needs a regex

1/ Split the string on newline, get array#1.

array#1 = [ “This is an example string”,”with spaces as well as
newlines”,”and needs a regex” ]

2/ For each element in array#1 , split based on your current regex which will break the strings
only on spaces as newlines have already been dealth with, this 2-D array is array#2

   array#2  = [ 
                ["This","is","an","example","string"] ,
                ["with","spaces","as","well","as","newlines"],
                ["and","needs","a","regex"]
              ]

3/ Process elements of array#2 as you want.
