I would need a regex to match my files named "something".Title"numberFrom1to99".mp4 on Windows' File Explorer, my first approach as a regex newbie was something like
"..mp4"
, but it didn't work, so i tried
"*.Title[1-9][0-9].mp4"
, that also did not work.
I would also like a tip on how to search regex related advices on Stackoverflow archive but also on the web, so that i can be specific, but without having the regex in the searching bar interact.
Thank you!
EDIT
About the second part of the question: in the question itself there is written "..mp4" but i wrote "asterisk"."asterisk".mp4, is there any universal way to write regex on the web without it having effect and without escaping the characters? (in that way the backslash shows inside the regex, and that could be misunderstood)
Try something like this:
(.*)\.[A-za-z]+\d+\.mp4
See this Regex Demo to get an explanation on the regex.
Use regex101.com to test your regexs
Here it is:
^[\s\S]*\.Title[1-9][0-9]?\.mp4$
I suggest regexr.com to find many interesting regexes(Favourites tab) and simple tutorial.

I'm using Notepad++ and need to update a file where there are various differences in earlier sections of the string of text and think Wildcards may help here. From the research I've done thus far, it isn't clear what syntax would be used for this.
Here's an example of the original string:
"EEID","SUPLIFE","Voluntary Life Insurance","500000.00","500000.00",0,276,10.62.0,0,0,"20151112","","A","","","","",""
I'd like to find a way to add wildcards in the places noted below as WILDCARD:
"EEID","SUPLIFE","Voluntary Life Insurance","WILDCARD","WILDCARD",WILDCARD,WILDCARD,WILDCARD,WILDCARD,WILDCARD,WILDCARD,"20151112","","A","","","","",""
The final output would then look like the following after the find/replace with wildcards to add VLIFE:
"EEID","SUPLIFE","Voluntary Life Insurance","500000.00","500000.00",0,276,10.62.0,0,0,"20151112","","A","VLIFE","","","",""
Thanks,
Brandon
Tested in Notepad++ and appears to work:
("EEID","SUPLIFE","Voluntary Life Insurance",([^,]+,){8}"","A",)("")(.*)
and replace pattern:
\1"VLIFE"\4
Regex101 example
I am trying to write a regex in C++ that would match any of the following statements:
0=250
26000=0.86M
0=250|18000=300
0=250|18000=300|26000=0.86M
I wrote the following and checked with regexr.com:
(([0-9]+=[0-9]+)|((\|[0-9]+=[0-9]|.[0-9]+)[Mm]))((\|[0-9]+=[0-9]+)|((\|[0-9]+=[0-9]|.[0-9]+)[Mm])?)+
It looks like it is working, but I do not understand one thing. I thought I needed double backslashes before ".", like:
(([0-9]+=[0-9]+)|((\|[0-9]+=[0-9]\\.[0-9]+)[Mm]))((\|[0-9]+=[0-9]+)|((\|[0-9]+=[0-9]\\.[0-9]+)[Mm])?)+
as I was advised in my other post. However, according to the online tester, this is not correct.
Can someone explain please?
Thanks a lot!
This depends on the flavor of regex that you are using. Regex doesn't have universal rules, and some of the main differences are what characters need to be escaped when.
I don't know what flavor your online tester was, but here is what c++ 11 uses for regex: http://www.cplusplus.com/reference/regex/ECMAScript/
You will need to escape all literal . and | characters in your regex according to this.
I'm lousy at regular expressions but occasionally they're the only thing that's the right solution for a problem.
Is there something in the .NET framework that allows you to input an unencoded string and get a pattern from it? Which you could then modify as required?
e.g. I want to remove a CDATA section that contains a file from some XML but I can't work out what the right pattern is for <![CDATA[hugepileofrandombinarydataherethatalsoneedstogo]]> and I don't want to ask for help each time I'm stuck on a regex pattern.
Such tools exist, google by "regex generator".
But, as suggested in comments, better learn regex. Simple patterns are easy. Something like <!\[.*?]]>
in your case.
There are Regex Design tools like expresso...
http://www.ultrapico.com/expresso.htm
It's not perfect but as there is no suitable .Net component the text to regex page at txt2re.com is the best I've seen for those people who occasionally need to build a regex to match a string but don't have the time to relearn regex each time they want to use one.
I am trying to make an if-then-else statement using RegEx. I want to match the text if it contains Monty and also contains Python. Also the text should get matched if Monty is not present in the text.
RegEx
(?(?=Monty)(?(?=Python).*|)|^.*).*$
Kindly help!
How about this:
(^(?!.*Monty(?!.*Python.*).*).*$|^.*Python.*Monty.*$)
This passes my tests, but let me know if it works for you.
I am not versed in lookahead regex but just tried to build the regex from what I understood from above description. Check the link to see if this is what you are trying to do.
try this instead
((?=Monty)((?=Python).*|)|^.*).*$
I tried to make regex syntax for that but I failed.
I have 2 variables
PlayerInfo[playerid][pLevel]
and
Character[playerid]
and I want to catch only the second variable,I mean only the world what don't contain PlayerInfo, but cointains [playerid]
"(\S+)\[playerid\]" cath both words and (\S+[^PlayerInfo])\[playerid\] jump on some variables- they contais p,l,a,y ...
I need to replace in notepad++,all variables like Text[playerid] to ExClass [playerid][Text]
Couple Pluasible solutions.
List item
Notepad has a plugin called python script. Running regex from there
gives full regex functionality, the python version anyway, and a lot
of powerful potential beyond that. And I use the online python regex tester to help out.
RegRexReplace plugin helps create regex plugins in Notepad++, so when you do hit a limitation, you find out a lot quicker.
Or of course default to your alternate editor (I'm assuming you have
one?) or this online regex tool is absolutely amazing. You
can perform the action on the text online as well.
(I'd try to build a regex for you, but I'm a bit lost as to what you're looking for. Unless the Ivo Abeloos got it. If you're still coming up short, maybe a code example along with values displayed?)
Good luck!
It seems that Notepad++ support negative lookbehind since v6.
In notepad++ you could try to replace (.+)\[(.+)\] with ExClass\[\2\]\[\1\]
Try to use negative lookbehind.
(?<!PlayerInfo)\[playerid\]
EDIT: unfortunately notepad++ does not support negative lookbehind.
I tried to make a workaround based on the following naive idea:
(.[^o]|[^f]o)[playerid]
But this expression does not work either. Notepad++ seems to fail in alternative operator. Thus the answer is: it is impossible to do exactly what you want. Try to solve the problem in other way or use alternative tool.
