I have a piece of text which is in the following format: "1. Question blah blah blah. goes on blah blah blah blah. Answer: Answer blah, blah goes on like this blah blah. 2. One more question. blah blah goes on like this again. Answer: Again and again, over and over." Now taking a piece of text, I have to break it down to pairs of question and answer sets so that they can be saved in to question model - which has a question and answer attribute. A single piece of text saved in a Post model needs to be parsed into a number of question models. The problem is that the text is very idiosyncratic, with numerous line breaks and carriage returns inside each question and answer but the numbering and the "Answer:" segments are present accurately. From what I read through various sources, this can be accomplished through regular expressions but I am not able to figure out how to go about this. Could someone explain how this can be accomplished for this particular case?

In a nutshell you tell it to scan until it finds text matching a particular pattern (in your case the beginning of question and beginning of answer markers), and it tells you all the text it consumed in between.
