我有很多网址,大约100K。
它看起来像这样:

我听说正则表达式是这样做的一种方式,所以我现在已经花了好几个小时来讨论这个问题,而且我即将耗尽时间。
有人可以帮助我吗?

答案 0 :(得分:2)
您可以使用:
(blog.example.com/\w+\/?).*
将其放入查找中并确保在搜索模式中选择“正则表达式”。
在替换中,放:
\1
并替换所有。
答案 1 :(得分:0)
这是要搜索的正则表达式。
^([.\w]+\/\w+\/?).*
这是替代品。
\1
让我们分解吧。正则表达式看起来像是在呼叫调制解调器,除非你仔细分解它们。
^ only match strings starting at the beginning of a line.
( begin gathering a bunch of stuff so we can replace it with \1
[.\w]+ accept a sequence of either dots or characters that appear in words
\/ accept a /
\w+ accept a sequence of characters that can appear in words
\/? accept a /, optionally (hence the ?)
) the end of the parenthesis started above
.* accept the rest of the string.
请注意,我使用+字符表示重复,因为它匹配一个或多个字符。我可以使用*,并在正则表达式的最后一项中这样做。匹配零次或多次重复。
