查找字符串所在行下面的内容不是固定的。
上面代码能实现。
用正则应该更快一些，
FullDetectTime.*?\r([\s\S]*?)\n\s*\r
但是不知道正则这样用对不对！

FullDetectTime\V+\R([\s\S]+)

使用a版的正则，如果最后面有空白行的话，也会匹配到空白行。
FullDetectTime\V+\R([\s\S]+)\n\s*\r
我在后面加上红色的就把空白行去掉了，不知道这样处理对不对？

另外A版常用\V，请教A版，\V \R是什么意思呢？一般怎么用呢？一般的教程这两个都是小写的

我 ...

如果要排除最末可能有的空行可以

FullDetectTime\V+\R([\s\S]+?)\s*$

正则里面大小写都是有不同意义的，\V是指非垂直空格，即非回车换行的所有字符；\R是指回车换行，但如果是单独的回车或换行也能匹配。这些帮助文档里都有说明。正则的写法可以千变万化，没有固定的模式或组合，达到目的就行。当然，数据量较大时不同的写法效率可能天壤之别。

谢谢a版的解惑，a版的正则功力真是深厚！
