保存的图案后立即替换数字 [英] Replacing digits immediately after a saved pattern

问题描述

搜索的模式类似于text9

我搜索(text)9

我想用\15代替，这样我会得到text5，但是它只是给了我text.

I want to replace with \15 so that I would get text5 but instead it's just giving me text.

除数字外，其他任何字符都有效.

Any other character works except for digits.

推荐答案

事实证明，PCRE样式的反向引用不起作用.

As it turns out, the PCRE-style back-references do not work.

因此，您必须使用\015替换为第一个捕获组(\01)和5捕获的文本.

So, you have to use \015 to replace with the text captured with the first capturing group (\01) and 5.

由于不能有超过99个捕获组，并且\之后的两个数字都被当作后向参考组号，因此\01被解释为对第一个组的参考，其余为文字数字.

Since there cannot be more than 99 capturing groups, and both the digits after \ are treated as back-reference group number, \01 is interpreted as the reference to the first group, and the rest are literal digits.
