split() can be asked to include it, though it puts it in a separate  
field:

 >> data = " This is a declarative sentence. And is this a question?  
Yes! "
=> " This is a declarative sentence. And is this a question? Yes! "
 >> data.split(/([.!?])\s+/)
=> [" This is a declarative sentence", ".", "And is this a question",  
"?", "Yes", "!"]

Hope that helps.
