regex: match line and proceeding lines until match but include contents before and after match -

i trying scan log file until match1 shows proceed match lines after match1 until match2 found. but! need match contents before match1 on same line , contents after match2 on same line.

so far using following mutliline flag cannot figure out how gather before , after content on respected lines of matches.

match1(.*)match2

2015-05-05 17:08:25 name: line should not included   2015-05-05 17:08:25 name: match1   2015-05-05 17:08:25 name: contents , stuff   2015-05-05 17:08:25 name: match2 more stuff   2015-05-05 17:08:25 name: line should not included   

i want match:

2015-05-05 17:08:25 name: match1   2015-05-05 17:08:25 name: contents , stuff   2015-05-05 17:08:25 name: match2 more stuff   

note: beginning of each line not numbers , there complete blank lines between intended match.

using multiline option (/m or (?m) in flavors) , not using singleline option (/s or (?s)), can match with

.*match1[\s\s]*?match2.*
