Perl Regex：匹配这个组，但没有这个模式

Question

我需要提取一些以双引号开头和结尾的文本 " 但如果它检测到多个双引号则不会提取。

我尝试使用不同的 look-arounds，positive/negative look-aheads 和 look-behinds，但它会导致错误。

在我上面的示例中，我想排除数据

"XxXXXXX - ""                                """"XX""""""",

和

"XxXXXXX - ""XXXXX XXXXXXXX 1.4.90          """"X2""""""",

免于匹配。

我在这里看到了其他一些答案，但是每当我使用负向后视时，我都会收到错误消息，正向前视和负向前视都没有问题，但它不起作用。

Edit:
I've added some examples regex in the link provided, and also more example data. However, I still don't want to match data above by the current regex.

Answer 1

使用这个怎么样：

"([^"]+?)"(,|$)

可以看到here 还有 here

Thanks for this one. Strange, I think I've tried this one before. But didn't get the result I've expected. Maybe it's because I didn't wait for it to be matched again.
