Treat the string as multiple lines. That is, change "^" and "$" from
matching the start of the string's first line and the end of its last
line to matching the start and end of each line within the string.
I almost always use /xms for my REs. This allows for significant
readability - at the cost of significant number of lines. Check out
Damian Conway's "Perl Best Practices" Regular Expression chapter.
