如何匹配除一组连续字符之外的任何字符？

Question

我正在尝试匹配字符所有字符，直到模式A0343443（A[0-9]+）

输入：

A546454 : This and that happened at C:\User\John\Documents\folder. There was an error reading 
the file
B546454 : This and that happened at C:\User\John\Documents\folder. There was an error reading the file
A595949: This other thing happened at C:\User\John\Documents\....

期望的输出：

A546454 : This and that happened at C:\User\John\Documents\folder. There was an error reading the file
A595949: This other thing happened at C:\User\John\Documents\....

由于行结尾不确定，我希望在到达A[0-9]+或B[0-9]+时结束 我尝试了积极的前瞻：

^(?=A[0-9]+)

但是在首个A

时失败了

即。 Alot of chocolate导致它停止。

有什么想法吗？

谢谢

由于您的行以A或B开头，因此您可以使用否定前瞻。

^(?!B[0-9]+).+$
