regexp来匹配。 和空白行

Question

i'm new to regexp and I'm stuck with trivial parsing task; Giving following structure i need regexp that matches all text between empty lines, so i could iterate through array of matches, and parse each item as a question

id1. "question title 1"
* variant one
* variant two
* three // comment

id2. "question title 2"
+ variant one
+ two
+ three

id3. "Anoter question title"
another variant

Answer 1

You can use \\. ".* \\. ".* this will give you . "question title 1" as one of the match. You can read from fourth char to last but one.

I couldn't figure out a way to match both question and answer line using regular expression. Because, this regular expression will match multiple lines but \\. "[\\s\\S]+ \\. "[\\s\\S]+ but it will match until end of the string matching all questions and answers into a single string.

If we assume that the answers will always start with either + or *, Another alternative is to use (\\. ".*)|([\\*\\+].*) This will match both questions and answers. However questions and answers will be separate matches.

Another way is to split the string using id. " id. " This will give each of your question and answer into another string. However you may have to remove the " at the end of the question manually.

Another way I can imagine is splitting entire string using ^\\s*$ . This will split the string using blank line and give you both question and answer as one single group. I hope this helps.
