javascript正则表达式，以匹配2个html注释标签之间的所有内容

Question

I have to create a regex which will match anything (including line breaks) between 2 html specific comment tags. Here is an example for some html:

<!-- build-remove-start -->
<!-- bower:js -->
<script src="../bower_components/jquery/dist/jquery.js"></script>
<!-- endbower -->
<!-- build-remove-end -->

<!-- inject:vendor:js -->
<!-- endinject -->

I would like to match every thing between <!-- build-remove-start --> and <!-- build-remove-end --> not including the comment tags (I mean not to remove the comments tags, only what's inside).
I have tried:
<!-- build-remove-start -->[\\s\\S]<!-- build-remove-end -->
But it doesn't work. Here is a link to test the regex:

Answer 1

You need to add * after [\\s\\S] .

/<!-- build-remove-start -->([\s\S]*?)<!-- build-remove-end -->/gmi

Also I recommend adding ? after * so it makes it lazy. This way you can have the example below, othwerise the this won't be removed line will be matched.

<!-- build-remove-start -->
//remove this
<!-- build-remove-end -->

This won't be removed

<!-- build-remove-start -->
//Remove this
<!-- build-remove-end -->
