匹配特定句子之外的单词

Match word outside of specific sentence

我想知道是否可以匹配句子外的单词。

这是我目前使用的正则表达式:

/(exchange|occasion|second hand)/im

现在我只想匹配这句话之外的这些词:

Shown prices, for exchange of ocassions are only for indication.

但我不确定该怎么做。

您可以像这样在交替的 LHS 上使用 PCRE verb (*SKIP)(*FAIL) to match and skip anything

/Shown prices, for exchange of ocassions are only for indication\.(*SKIP)(*F)|\b(exchange|occasion|second hand)\b/i
