问题
I want to write a regex what matches everything except words between quotes. Ex.:
Lorem ipsum "dolor" sit amet, consectetur "adipiscing" elit.
Nunc ultrices varius odio, "ut accumsan nisi" aliquet vitae.
"Ut faucibus augue tortor, at aliquam purus dignissim eget."
So I want a regex what matches the following strings:
- Lorem ipsum
- sit amet, consectetur
- elit. Nunc ultrices varius odio,
- aliquet vitae.
I only have the following expression that matches substrings inside quotes:
([\"'])(?:\\\1|.)*?\1

This regex works:
([^"]+?)(".*?"|$)

1st Capturing Group ([^"]+?)
Match a single character not present in the list below [^"]+?
+? Quantifier — Matches between one and unlimited times, as few times as possible, expanding as needed (lazy)
" matches the character " literally (case sensitive)
" matches the character " literally (case sensitive)
.*? matches any character (except for line terminators)
*? Quantifier — Matches between zero and unlimited times, as few times as possible, expanding as needed (lazy)
" matches the character " literally (case sensitive)

If you are using PCRE, you may use
([\"'])(?:\\.|(?!\1)[^\\])*?\1(*SKIP)(*F)|(?:[^\\"']|\\.)+
See its demo.
Details
([\"'])(?:\\.|(?!\1)[^\\])*?\1- a"..."or'...'substring with escaped quote support:([\"'])- Group 1 (referred to with\1): a"or'(?:\\.|(?!\1)[^\\])*?- 0+ occurrences (as few as possible due to*?being lazy) of:\\.- an escape sequence|- or(?!\1)[^\\]- any char other than\and the quote char in Group 1
\1- Same value as in Group 1 ("or')
(*SKIP)(*F)- PCRE verbs that omit the current match and make the engine proceed to the next match from the current match end position|- or(?:[^\\"']|\\.)+- 1 or more occurrences of:[^\\"']- a char other than\,'or"\\.- an escape sequence.
