"^"                    Assert position at the beginning of a line (at beginning of the string or after a line break character) (line feed)
"("                    Match the regex below and capture its match into backreference number 1
Match this alternative (attempting the next alternative only if this one fails)
"("             Match the character “(” literally
"[ivxcdlm]"      Match a single character from the list “ivxcdlm” (case insensitive)
"+"           Between one and unlimited times, as many times as possible, giving back as needed (greedy)
")"             Match the character “)” literally
"|" 
Or match this alternative (attempting the next alternative only if this one fails)
"("             Match the character “(” literally
"[a-z]"          Match a single character in the range between “a” and “z” (case insensitive)
