Javascript doesn't have DOTALL flag in its regex engine.

But Javascript way to make dot match newlines is:

string.match(/<block>([\s\S]*?)<\/block>/ig);

[\s\S] in place of . matches any character including newlines.

You must replace the dot . by [\s\S] because the dot doesn't match newlines.

/<block>([\s\S]*?)<\/block>/g

An alternative is to use [^<]* if no other tags are nested:

/<block>([^<]*)<\/block>/g

However a code like this:

<block> abcd
    <block>efgh</block>
</block>

will fail with the first pattern, and you can't solve the problem with javascript regexes.
