Lazy Quantifier Needed

Resurrecting this question because the regex in the accepted answer doesn't seem quite correct to me. Why? Because

(?<=This is)(.*)(?=sentence)

will match my first sentence. This is my second in This is my first sentence. This is my second sentence.

See demo.

You need a lazy quantifier between the two lookarounds. Adding a ? makes the star lazy.

This matches what you want:

(?<=This is).*?(?=sentence)

See demo. I removed the capture group, which was not needed.

DOTALL Mode to Match Across Line Breaks

Note that in the demo the "dot matches line breaks mode" (a.k.a.) dot-all is set (see how to turn on DOTALL in various languages). In many regex flavors, you can set it with the online modifier (?s), turning the expression into:

(?s)(?<=This is).*?(?=sentence)

For example     lt  This is        sentence    Regexr  I used lookbehind    lt    and look ahead      so that  This is  and  sentence  is not included in the match  but this is up to your use case  you can also simply write This is    sentence   The important thing here is that you activate the  dotall  mode of your regex engine  so that the   is matching the newline  But how you do this depends on your regex engine   The next thing is if you use    or      The first one is greedy and will match till the last  sentence  in your string  the second one is lazy and will match till the next  sentence  in your string   Update  Regexr  This is  s     sentence   Where the   s  turns on the dotall modifier  making the   matching the newline characters   Update 2      lt  is             s       is matching your example  This is  a simple  sentence   See here on Regexr

RegEx to match everything between two strings using the Java approach   List lt String gt  results   new ArrayList lt  gt       For storing results String example    Code will save the world     Let s use Pattern and Matcher objects to use RegEx         Pattern p   Pattern compile  Code         world        java util regex Pattern  Matcher m   p matcher example                          java util regex Matcher    Since Matcher might contain more than one match  we need to loop over the results and store it   while m find         Loop through all matches    results add m group       Get value and store in collection      This example will contain only  will save the  word  but in the bigger text it will probably find more matches
