I need a expression to extract some alternatives. The input is: asd11sdf33sdf55sdfg77sdf I need the 11 33 and 55 but not 77. I tried first: .*(((11)|(33)|(55)).*)+.* So I got only 55. But with lazy (non greedy) .*?(((11)|(33)|(55)).*)+.* I got only 11. How to get all? regards Thomas JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)
