Matching part of regex in substrings

edit: see Matching part of regex in substrings

I don't know if title is good but let me give some examples.

this is the pattern i came up with:

/(---+\s*([^\s-]+)\s*---+)(.*?)(---+\s*[^\s-]+\s*---+)/gs

These are scenarios:

--- content ---

lorem ipsum dolor sit amet
--- --- --- --- --- ---
Suspendisse nec dui in orci ullamcorper porttitor. 
Sed lobortis dui ut placerat tempor. Donec lacus nibh, porta vitae mattis ac, facilisis dictum ipsum.

--- content ---

--- sub-content 1 ---

lorem ipsum dolor sit amet
--- --- --- --- --- ---
Suspendisse nec dui in orci ullamcorper porttitor. 
Sed lobortis dui ut placerat tempor. Donec lacus nibh, porta vitae mattis ac, facilisis dictum ipsum.

--- sub-content 1 ---

--- sub-content 1 2 3 ---

lorem ipsum dolor sit amet
--- --- --- --- --- ---
Suspendisse nec dui in orci ullamcorper porttitor. 
Sed lobortis dui ut placerat tempor. Donec lacus nibh, porta vitae mattis ac, facilisis dictum ipsum.

--- sub-content 1 2 3 ---

I can match if space count known but couldnt figured out where space count between non-space characters unknown. Basically i want to match all strings as long as there is a non-space character between first and end ---XXX---

You may use the following regex with a multiline flag (note you do not need any flag if you use the pattern in Ruby):

^(---+\s+([^\s-].*?)\s+---+)$(.*?)^(---+\s+([^\s-].*?)\s+--+)$

See the regex demo. I added line start/end anchors ^ and $ and changed [^\s-]+ that did not allow any intraword hyphens to [^\s-].*? that requires a char other than whitespace and a hyphen and then anything up to the trailing hyphens.
