Question

我想写一个正则表达式，除了引号之间的单词之外的所有内容。例如：

 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."

所以我想要一个与以下字符串匹配的正则表达式：

Lorem ipsum
坐下来，奉献
ELIT。 Nunc ultrices varius odio，
aliquet vitae。

我只有以下表达式匹配引号内的子串：

([\"'])(?:\\\1|.)*?\1

Answer 1

这个正则表达式有效：

([^"]+?)(".*?"|$)

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)

如果您使用的是PCRE，则可以使用

([\"'])(?:\\.|(?!\1)[^\\])*?\1(*SKIP)(*F)|(?:[^\\"']|\\.)+

请参阅its demo。

<强>详情

([\"'])(?:\\.|(?!\1)[^\\])*?\1 - 带有转义引用支持的"..."或'...'子字符串：
- ([\"']) - 第1组（简称\1）："或'
- (?:\\.|(?!\1)[^\\])*? - 0次出现（由于*?懒惰而导致的）：
  - \\. - 转义序列
  - | - 或
  - (?!\1)[^\\] - 除\以外的任何字符和第1组中的引用字符
- \1 - 与第1组中的值相同（"或'）
(*SKIP)(*F) - 省略当前匹配并使引擎从当前匹配结束位置继续进行下一场比赛的PCRE动词
| - 或
(?:[^\\"']|\\.)+ - 出现1次或多次：
- [^\\"'] - \，'或"
- \\. - 转义序列。
