g
1st Alternative
".*?"(*SKIP)(*FAIL)
" matches the character " with index 3410 (2216 or 428) literally (case sensitive)
.
matches any character (except for line terminators)
*? matches the previous token between zero and unlimited times, as few times as possible, expanding as needed (lazy)
" matches the character " with index 3410 (2216 or 428) literally (case sensitive)
(*SKIP) acts like (*PRUNE), except that if the pattern is unanchored, the bumpalong advance is not to the next character, but to the position in the subject where (*SKIP) was encountered
(*FAIL) verb synonymous with (?!). Forces a matching failure at the given position in the pattern
2nd Alternative
(\w+)
1st Capturing Group
(\w+)
\w
matches any word character (equivalent to [a-zA-Z0-9_])
+ matches the previous token between one and unlimited times, as many times as possible, giving back as needed (greedy)
