I have this regex string:
("prodcssstart.*prodcssend","xx")
and my file like this:
prodcssstart
<!--<link href="content/bundles/css.min.css" rel="stylesheet" />-->
prodcssend
But when I run it then it fails to find the expression.
Can someone suggest what I might be doing wrong, I've simplified it so much but I am thinking maybe there is a problem with the .* that I use to match everything. Any help would be much appreciated.
First of all, you can't parse HTML with regex.
But in your case the problem is most likely caused by newlines, because by default the dot doesn't match the newline. You need to pass the proper switch to disable this (e.g. re.DOTALL in Python and s in Perl).
You could come up with a tempered greedy token solution:
prodcssstart
(?:(?!prodcssend).)*
prodcssend
Breakdown:
look for prodcssstart
match any character as long as it is not followed by prodcssend
match prodcssend
See a demo on regex101.com (mind the different modifiers!).

I want to negate the outcome of the regex pattern, so that it should return everything except the regex outcome.
Sample String:
SMTP:test.abc#xyz.com;smtp:test.123#xyz.biz;sip:test.123#xyz.biz
I have written a below regex which gives output as- test.abc#xyz.com
(?<=SMTP:)(.*?)(?=;)
Now i want everything except the above outcome i.e
SMTP:;smtp:test.abc#xyz.biz;sip:test.abc#xyz.biz
I am trying to negate but it is not working.
Any help is much appreciated.
It might be overcomplicated, but if you need multiline matching and a smtp account can be in the beginning of a line, this:
(SMTP:)|(;[^(SMTP)]*)|(^[^(SMTP)]*)
would match:
SMTP:
anything after a ; up until another SMTP
anything at the beginning of a line (no need of ;) up until another SMTP
Have a look at some tests here.
This can break down if an email name contains SMTP in it, but I hope you won t have any.
Another approach is use your matching regex, (?<=\SMTP:)(.*?)(?=\;), and keep deleting what it matches from the string.

The problem in Akeneo seems to be that simple regex combinations not working. I think the functionality (a single or group regex combination) is not integrated/implemented proper in Akeneo. If there is anybody out there who knows a trick to do a regex combination please let me know.
Tried to figure out how to make regex with | OR working in Akeneo "attributes".
the simple Example not working either a syntax error or no matching in Akeneo:
find this "323"
or find "123456"
\d{3}|\d{6}
Can anybody help?
According to the documentation, you need to use regex literal notation, and anchor the match both at the start and end of the string (so, add a grouping):
/^(\d{6}|\d{3})$/
Here, / are regex delimiters, ^ matches the start of string, (...) is a capturing group that contains two alternatives, six digits or three digits, and then end of string anchor, $, follows.

How to process search results using regex?
E.g., I have a file with many strings like AB.
I want to get: 'AB'.
The letters always differ.
So I would search for the regex pattern ^\w+\n and want to use the search result, let me use '$#' to depict it, to get '$#'.
Regex:
(?<=:)([^,]+)
REplacement string:
'$1'
DEMO
Just to clarify: You want 71:A,72:BC,73:ABD to become 71:'A',72:'BC',73:'ABD' right?
Do a find/replace in whatever language or program you are using:
Find: (\w+)
Replace: '$1'
This finds ANY multi-letter string in your file and puts ' around it. if you only want to do the ones with [number:string] you will need to use a look-ahead like (?=\d+:) in front of the (\w+). So the whole Find would then look like (?=\d+:)(\w+), similar to what Avinash Raj has posted.

I'm searching for a pattern for matching numbers with hyphen at the end like this :
125,000-
1.234,567-
60,000-
Just try with following regex:
/\d[.,\d]*-/
Or even:
/\d([.,]?\d+)*-/
NOTE Aleš Krajník's answer is basically the same as the answer I finally came to, except that his uses non-capturing grouping (as captures are not required)... he should get the votes IMHO as he was first
Note that in the following answer I'm assuming that , comma is the decimal separator, and that the . point is the thousands separator (eg for European numbering).
I believe the following is "correct":
^\d{1,3}(.\d{3})*(,\d+)?-$
This matches eg:
1-
12-
123-
123.456-
123.456.789-
1,0-
1,01-
1,001-
1,0001-
123.456,01-
123.456.789,0001-
etc
But will not match eg
1234-
123,-
123.4-
123.1,001-
123.45-
1..1..1-
1.1.1-
1,1,1-
.,-
etc.
The exact regex should read: \d{1,3}(?:\.\d{3})*(?:,\d+)?-
Try something like this:
[0-9.,]+-
\d{1,3}(?:[,]\d{3})*- takes internationalisation into account. The one below allows strings like 1..9 to match, which really should not.

I hate to ask specific question, but i need the regex code for matching strings like :
{block any_single_word_here}
Anything Here
{/block}
Your original query is very close, albeit a little verbose. It can be shortened to:
/{block (.+?)}(.+?){\/block}/
(The ? modifier stops the + from being "greedy", so you don't have to explicitly stop the match at the next } or {.)
Next you have to consider that . won't match newlines by default. You can change this with the /s flag:
/{block (.+?)}(.+?){\/block}/s
Here's a demo.
And here's the documentation from man perlre:
s
Treat string as single line. That is, change "." to match any character whatsoever, even a newline, which normally it would not match.
In javascript (added escape to end of lines in original string) I added a \s* (zero or more spaces) to your regex and it outputs a match for any_single_word_here and Anything Here fine...
alert( "{block any_single_word_here}\
Anything Here\
{/block}".match(/\{block ([^\}]+)\}\s*([^\{]+)?\{\/block}/) )
For simpler regex, remove the unneccessary escaping, and just capture with . rather than complex [^\}]
/{block (.+)}\s*(.+){\/block}/
Does this do the job?
/\{block \w+\}\r?\n.*?\r?\n\{\/block\}/i
