need of explanation of find and replace with option regex
-
thanks for another suggest of a possible solution, but I tested it and I’m not still getting any findings,
but I have compared your Debuginfo with mine and found following differences:Notepad++ v7.5.4 (64-bit)
Build time : Jan 1 2018 - 01:50:29
Path : C:\Program Files\Notepad++\notepad++.exe
Admin mode : OFF
Local Conf mode : OFF
OS : Windows 8.1 (64-bit)
Plugins : DSpellCheck.dll mimeTools.dll NppConverter.dll
and NppExport.dll is failingI think perhaps, that the bold marked parts makes the differences between working and not working.
But how can I change the bold marked settings?I don’t think, the reason lies in the italic marked settings (Bitsize or OS)
And how can I insert a screenshot in this reply?
Coppy and paste doesn’t work and I don’t find any button to insert an image …
I’d like you to see my inserts and settings for comparing.
I could give you only my debuginfo, because I could copy the text with option “copy debug info into clipboard”I see forward to your response,
many thanksAndrea

Hi Andrea,
the forum doesn’t have an option to upload images but the
used html renderer (markdown) knows a syntax to embed external images.
So what most do is to upload the image to a hoster like imgur.com and then,
once the image has been created, right-click on the image and do save image address
and use the syntaxto embed it into the post.
I don’t think the bolded lines have any effect on it but who knows.
Admin mode is ON if you right-click to the npp shortcut and do
run as administrator, if you don’t do it -> OFFLocal Conf mode is ON if you have a file doLocalConf.xml
in the same folder where your notepad++.exe is, if you don’t have that file -> OFF
The file is empty, only its existence is needed to switch from off to on.
It basically informs npp that it should not use/create the user config files under
%APPDATA% but rather use the ones in the install directory.The export plugin gives the additional features to copy the text in rtf and/or html format.
Did you try Peters suggestion as well?
Or could you provide more, obfuscated if needed real data to see if something else
breaks the regex?Cheers

Hi Peter,I tested your version with $ at the end of the last line too,
but I got the same errormessage again.
In my answer to Claudia I put the debuginfo perhaps it will help, but I don’t know where I can make the alterations for the bold marked information (admin mode and local conf mode). -
At this point it is probably best to do what @Claudia-Frank suggested and post some real data. I describe how to reasonably do that (post some data) in this thread. Try to avoid a straight paste of data into a posting as you did in the first post in this thread, as often data contains special markdown commands.
Another possibility is to use a site like www.textuploader.com and then post the link in a reply here. Of course, as Claudia said if your data is “sensitive” you may want to replace any sensitive info with different (but format-equivalent) dummy data first.

@Peter Jonesthanks for the tip with the link to imgur and other webdrives, here is the image:

I tested it with Peter’s suggestion as well and I got the same errormessage.
I can give you the whole file, because it is no secret - it’s the latest taxlist for wages and you can get it in the the web. But it is too big for my purpose and you can get it only as an pdf-file. I converted it into a textfile and try to shorten it, because I’m only interested in taxclass I (not married, no bonus for children, no additional tax for church/religion)
Befor I can import it to an xls(x) file, there is a want for a slight trimming for a better import, because there are too many irregularities for import.And here is the file

Thank you for your support to all

Use
to embed it – the initial exclamation point will allow the forum to render the image, saving us from having to click to the site:
In the first image, you can see that your roman-numeraled lines are all indented. The regex assumed that theIIwere the first characters on the line. It’s easy to fix:(?s)^[\x20\x09]*II\x20.+?Steuerklasse\x20VI$The
[\x20\x09]*will match 0 or more spaces or tabs between the start-of-line and theII, so it won’t matter whether it’s space-indented, tab indented, or not indented. (I wanted to use the\wwhitespace escape, but it also matches newline, even with(?-s:\w*).)If there’s any possibility of trailing spaces after the
VI, you might want to use
(?s)^[\x20\x09]*II\x20.+?Steuerklasse\x20VI[\x20\x09]*$ -
See why posting actual data is a good thing? It allowed the whitespace on the lines before the
IIto be seen by readers of this thread! :-)
And the problem to be detected and solved–quickly! :-D -

Image just posted is of dubious value; @PeterJones already posted it as well as solved your original problem…or is there something new to keep this going?

here is the new embeding of the image:
Thanks to Peter for this tip
I tested the new suggestions, but I get always Can’t find the next …
It seems, as if Notepad++ think the searching syntax is part of a text, not an order.
I tried it with option advanced (in German “erweitert”) and with option regex (in German “reguläre Ausdrücke”) I was trying Peters last two expressions one by one by copy and paste, the problem is not solved …here is the last sample:

Hello, @andre-seyfarth,
Not totally sure that I’ve found out the problem, but I would advice to tick, in the Suchen dialog, the
Am Ende von vorne beginnenoption (Wrap aroundoption in English )With that option set, when you begin your search, for instance, at the middle of your file, The regex engine first searches occurrences from that location to the very end of your file. Then, it go back to the very beginning of the file and continue searching until the initial location of your cursor, before the search/replace operation !
Best Regards,

@guy038
I tried that option too, but I got no result …
Is there a setting in the programm itself, which is restraining the search-routine to recognize the syntax as a syntax and not as a part of a normal text?
Thats my hunch, that the searchroutine of np++ can’t recognize the syntax anyway or simply ignores the fact, that it is a syntax ;-)Here is the new sample with option Wrap around:
thanks for your patience to all, I don’t know, why all your suggestions don’t work in my version of npp++
when I use the same options you have suggested and insert the syntax into the field “search what” by copy and paste.
I compare the syntax, which you have written down with the one I have put it copy and by paste into the field every time before I push the button “Find next”. I don’t dare to push the button “replace” because I don’t want to purge the file.kind regards

The screenshot you showed is back to using the old regex, which didn’t allow for spaces before the
II, and required a newline at the end (so won’t match the very last occurrence) – we already showed that was wrong for your data, and explained why. Please try it again with one of the new ones, like(?s)^[\x20\x09]*II\x20.+?Steuerklasse\x20VI[\x20\x09]*$. -
I know you haven’t asked for it, but I assume if you ever make my regex match, you’ll soon be noticing something I saw.
If you use the regex
(?s)^[\x20\x09]*II\x20.+?Steuerklasse\x20VI[\x20\x09]*$on the file quoted here (which is a simplified version of your file):111,11I Header II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VI 111,11I Header II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 NoMatch VI 111,11I Header II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VI 111,11I Header II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 NoMatch VI 111,11I Header II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VIThen the second match will be the second and third “paragraph” (as shown in the left side of the image below). (I have defined “paragraph” to mean the entire 6-line grouping)
However, if you modify the regex to
(?s)^[\x20\x09]*II\x20(?:.(?!^[\x20\x09]*II\x20))+?Steuerklasse\x20VI[\x20\x09]*$, it will match just the third “paragraph”, as seen in the lower-right, which I am assuming what you’ll eventually want.
Explanation: the
.+?from the original regex will match any character, one or more times. By replacing that with(?:.(?!^[\x20\x09]*II\x20))+?, I am able to restrict it to match any character, one or more times, as long as that character isn’t followed byIIat the beginning of a line. To break it down:(?:___)= this wrapper says “match___as a group, but (if also using a replace string) don’t capture it into the$1”. (You don’t say whether you’re ever going to try a Replace to go with this Find What, so I thought I’d make it safe(?:___)+?= match one of more of this group, but make it as short as possible (so if you’ve got two matching "paragraph"s in a row, it won’t be greedy and will only highlight one “paragraph” at a time)- Moving inside, the dot
.still matches one character. .(?!___)= this second parenthetical is a “negative lookahead assertion” (as indicated by the?!). Together, this means "look for any one character, as long as it’s not followed by the___. The lookahead does not “use up” any characters, so.(?!___)still only matches one character- By using
^[\x20\x09]*II\x20(which was what we used to define the start-of-match, earlier) as the___in the negative lookahead, we are saying “we don’t want our standard start-of-match sequence to be anywhere inside our match”.
(I had seen this problem before I made yesterday’s post, but I didn’t have a solution at that point, so wasn’t going to mention it. :-) I thought I was going to have to hand it off to @guy038 if @Andrea-Seyfarth asked about it… but I thought of the negative lookahead while lying awake in bed before my alarm went off this morning. I tried it as soon as I could, and it worked… Hopefully this helps.)

Hello, @andrea-seyfarth, @peterjones and All
Here are two regexes :
Regex A :
(?s)^\h*II\x20.+?\R\h*VI\x20(?-s).+\R?Regex B :
(?s)^\h*II\x20((?!Header).)+?Steuerklasse\x20VI(\R|\z)that I tested against the text below :
111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VI VII 777.77 Steuerklasse VII VIII 888.88 Steuerklasse VIII 111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 ----- NO MATCH 1 ----- VI VII 777.77 Steuerklasse VII VIII 888.88 Steuerklasse VIII 111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VI VII 777.77 Steuerklasse VII VIII 888.88 Steuerklasse VIII 111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 ----- NO MATCH 2 ----- VI VII 777.77 Steuerklasse VII VIII 888.88 Steuerklasse VIII 111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 ----- NO MATCH 3 ----- VI VII 777.77 Steuerklasse VII VIII 888.88 Steuerklasse VIII 111,11I Header I 000.00 II 222,22 III 333.33 IV 444.44 V 555.55 Steuerklassen V und IV VI 666.66 Steuerklasse VI
The regex
Acatches the entire FIVE lines, beginning with Roman numberIIand beginning with Roman numberVI( with possible horizontal blank characters before ), whatever their contentsAnd the regex
Bcatches the entire FIVE lines, beginning with Roman numberII( with possible horizontal blank characters before ) and ending with the string Steuerklasse VI, ONLY IF the stringHeadercannot be found, at any position, of the smallest multi-lines sequence of characters, after the regex\h*II\x20till the regexSteuerklasse\x20VI!So, Peter, as you can see, I used the negative look-ahead
(?!Header), which is tested at any position of the.=> the syntax((?!Header).)+?. Note also, by I preferred to get the entire lines, with their End of Line chars ! So, when the replacement zone is empty, it does not remain any blank line, afterwards :-))I also, used the alternative
(\R|\z), just in case the very last line would be a lineVI 666.66 Steuerklasse VI, without any line-break !Best Regards,

The word “Header” was my invention, and not in any of @Andrea-Seyfarth’s examples, so that shouldn’t be used for a regex we suggest to her. Sorry for muddying the waters with my example file.
I like your cleaner
\hfor the horizontal space (that escape sequence hadn’t yet stored in my long-term regex memory; some day, maybe even today, it will).Thanks for continually sharing your regex expertise with us. I’m always amazed by your expressions, and the quality of your explanations.
Hopefully, we’ve helped Andrea in the process. :-)
