我正在尝试将 Regex 用于我正在做的工作项目。我有一组看起来像这样的数字:

我想只用一个或两个正则表达式语句来获得每行中的第 10 个数字(165)。该数字偶尔会从 165 更改,因此我无法对其进行硬编码。到目前为止,我有:
([+-]{0,1}[0-9]{1,5})
([+-]{0,1}[0-9]{1,5})
([+-]{0,1}[0-9]{1,5})
([+-]{0,1}[0-9]{1,5})
([+-]{0,1}[0-9]{1,5})
([+-]{0,1}[0-9]{1,}[.]{0,1}[0-9]{0,5})|([+-]{0,1}[.]{1,1}(?=[0-9])[0-9]{0,5}))
([+-]{0,1}[0-9]{1,}[.]{0,1}[0-9]{0,5})|([+-]{0,1}[.]{1,1}(?=[0-9])[0-9]{0,5}))
([+-]{0,1}[0-9]{1,}[.]{0,1}[0-9]{0,5})|([+-]{0,1}[.]{1,1}(?=[0-9])[0-9]{0,5}))
([+-]{0,1}[0-9]{1,}[.]{0,1}[0-9]{0,5})|([+-]{0,1}[.]{1,1}(?=[0-9])[0-9]{0,5}))
([+-]{0,1}[0-9]{1,5})
这显然不是 1 或 2 步,而是 10 加,它给了我 9 分,我不想要。
这个问题已经解决了,但是现在又出现了一个新问题:
我以为:
(?#<INS:5>)
^.{53}([+-]?\d+)
\.\.\.\. \.\.\.
(?#<INS:5>)
^.{53}([+-]?\d+)
\.\.\.\. \.\.\.
(?#<INS:5>)
^.{53}([+-]?\d+)
\.\.\.\. \.\.\.
解决了我的问题,但事实证明此代码在以下情况下会中断:
9486 9 68 -133 9562 -0.0 -0.1 0.0 -0.2 106 60.00 .... ...
9455 3 63 -129 9521 -0.0 -0.1 0.0 -0.2 106 60.00 .... ...
9417 3 64 -132 9485 -0.0 -0.1 0.0 -0.2 89 60.00 .... ...
9367 3 60 -129 9431 -0.0 -0.1 0.0 -0.2 89 60.00 .... ...

9111 4 62 -127 9177 -0.0 -0.1 0.0 -0.2 89 60.00 .... ...
9041 -0 58 -126 9099 -0.0 -0.1 0.0 -0.2 89 60.00 .... ...
8969 6 57 -129 9032 -0.0 -0.1 0.0 -0.2 89 60.00 .... ...
8887 9 60 -132 8956 -0.0 -0.1 0.0 -0.2 73 60.00 .... ...
8802 5 62 -131 8869 -0.0 -0.1 0.0 -0.2 73 60.00 .... ...
8720 1 64 -132 8785 -0.0 -0.1 0.0 -0.2 73 60.00 .... ...
8634 9 66 -137 8710 -0.0 -0.1 0.0 -0.2 73 60.00 .... ...
当第 10 个数字低于 100 时,代码失败。有没有办法让它在 10 秒和 1 秒内不会中断?
