Regular expressions on strings with multiple newlines

im banging my head against a wall with this. Im sure theres an easy way
to solve this.

Say i have this string

"xxx cfghyrfhyuijhcdf xxxx"

and i want all letters between the x`s

i would write something like this

/x*?(.*?)x*/

but if there are some unknown number of newlines seperating those
letters like so

"xxx cfg\nhyrfh\nyuij\nhcdf xxxx"

that reg fails

I tried

/x*?(.|\n)*?x*/

but match[1] can return a "" if it reaches a newline first rather than
the full sequence of letters and newlines (i dont mind having the
newlines returned)

I know i can simply gsub all hte newlines out of the string first but
just wondering if theres a way round this with a regexp

"xxx cfg\nhyrfh\nyuij\nhcdf xxxx" =~ /x*?(.*?)x*/m

=> 0
Notice the m.
