Hi,

I am a newbie and the answer to this might be too simple.  
How do I improve the example below and reduce the number of passes  
over the string?

string = “This is an example string. The purpose is to save the  
delimiter during split. Does this work. Great!!!.”

re = /(.\s+)(\D)/  
string.gsub!(re,’\1’+’#’+’\2’)  
b = string.split(’#’)  
puts b

Thanks  
Ajith
