如何使用记事本++对文本行进行分组

Question

I find Notepad++ regex to be very different from regex in Microsoft Word. I was wondering how I can group several lines of text using Notepad++. I have a text file with 100+ URLs. They are written one URL address per line. I would like to group all of them by tens by removing the carriage returns from every first to 9th line, but retaining the carriage return on every 10th line and adding another carriage return thereafter. For example:

I want this:

http://website1.com
http://website2.com
http://website3.com
http://website4.com
http://website5.com
http://website6.com
http://website7.com
http://website8.com
http://website9.com
http://website10.com
http://website11.com
http://website12.com
http://website13.com
http://website14.com
http://website15.com
http://website16.com
http://website17.com
http://website18.com
http://website19.com
http://website20.com
http://website21.com
http://website22.com
http://website23.com
http://website24.com
http://website25.com
http://website26.com
http://website27.com
http://website28.com
http://website29.com
http://website30.com

to look like:

http://website1.comhttp://website2.comhttp://website3.comhttp://website4.comhttp://website5.comhttp://website6.comhttp://website7.comhttp://website8.comhttp://website9.comhttp://website10.com

http://website11.comhttp://website12.comhttp://website13.comhttp://website14.comhttp://website15.comhttp://website16.comhttp://website17.comhttp://website18.comhttp://website19.comhttp://website20.com

http://website21.comhttp://website22.comhttp://website23.comhttp://website24.comhttp://website25.comhttp://website26.comhttp://website27.comhttp://website28.comhttp://website29.comhttp://website30.com

Any help would be appreciated!

Answer 1

Ok, I have found a way:

There is a such possibility, but only with 6 entries in a row (longest regex is not parsed by the Notepad++).

1)So, open the file and remove from it all newlines characters, so the text will be a long-long line.

2)Open replace dialog, insert in the "Find what" field the next :

(http://[^\\:]*\\.comhttp://[^\\:]*\\.comhttp://[^\\:]*\\.comhttp://[^\\:]*\\.comhttp://[^\\:]*\\.comhttp://[^\\:]*\\.com)

and in the "Replace With" the next:

\1\r\n

Put the cursor at the first position in the text and press "Replace all"

So, the regex contains this (http://[^\\:]*\\.com){6} (the regex is repeated 6 times). If you work with Unix and you need unix-type new line style, replace this : \\1\\r\\n with this \\1\\n
