I have string :
/url?q=http://www.bbc.com/indonesia/berita_indonesia&sa=U&ved=0ahUKEwjhqsr6h73OAhVDu48KHTR1AKsQFghDMAs&usg=AFQjCNEv3lNjzDNxPjfpqOtOb0ApNzvCCA
I want to get the result like this :
http://www.bbc.com/indonesia/berita_indonesia
How can I do with using RegEx ?
Thanks
The first capturing group of the following expression will extract the part you want. \?q=([^&]+)
You can extract it with following regex:
/(http:\/\/.+)/
the first (and only) capturing group contains value of url.
Here you can see it in action and adjust for your prefferred language.
EDIT: this pattern will capture whole URL along with following query string. Do you need url with path and without query string?

I am having the following String
{'Sample': '#it{tq}', 'Yield': 0.011063753491221462, 'Error': 0}
and I would like to extract the value from 'Sample', that means '#it{tq}'. I tried that using a regular expression: 'Sample':(\s*.+?\s)
but its giving me: '#it{tq}', including that comma at the end. Does anyone know how to erase the comma at the end?
this regular expression should do the job.
regex: 'Sample':\s*('[^']*')
https://regex101.com/r/DL5Ltq/2
how about using this:
'Sample': '(.*?)',
beware that the regex in the accepted answer cannot process the case having single quote escape text inside the capture group like this: {'Sample': '#it'{tq}'}.
If you use (.*?), it greedily process any single character inside two single quote.

I want to select first two characters appearing on a given string like below.
in below example i would like the result to show "CJ" only.
";2;14;1;1;CJ;1;CT;1;DG;1;DJ;1;DT;1;QF;1;QG;1;QH;1;TA;1;TG;1;TK;1;TR;1;TW;1;TX";
([a-zA-Z]{2})
(): Capture the string into a group
[a-zA-Z]: Match any letter, upper or lower case
{2}: Match exactly 2 times
Make sure the "global" flag is not enabled ("global" allows returning multiple matches, not just the first)

this is part of my ansible hosts files:
[Arista]
Ars-898z.cnd0 arista_host=Ars-898z.cnd0.example.com
Ars-898y.mex0 arista_host=Ars-898y.mex0.exmaple.com
I want to somehow use filtering or regex to extract only cnd or mex (the string between first and second dot) in my ansible playbook and save it a variable such as "dcname" and use it create a folder.
Please let me know how I can do it. I have already searched stackoverflow but did not get any similar questions for ansible
How about this?
(?<=\.)[^.]+(?=\.[^.]*\.[^.]*$)
Regex101 demo.
Here is a more flexible solution:
(?<=\.)[^.]+(?=(?:\.[^.]*){3}$)
The 3 can be adjusted. It is the number of dots '.' that come after the matched substring. If you enter 2, you get "cnd0", if you enter 3, you get "cnd0 arista_host=Ars-898z".
Another demo.

I'm having another issue where I want to extract values from a string. Please take a look.
string anotherTest = "Hello World [A12345 **(05,00,45)**] - [518.6Z] [51.5]"
I would like the result to return "A12345" "518.6Z" "51.5".
What I highlighted in bold is what I'm having issue with.
I'm using c# and I've tried [(\D?\d+.?\d+\D?)] ... which is fine if I don't have what's in parentheses.
You need to extract the first word from a [ ... ] substring. Use groups:
.*?(\[([^\[\] ]+).*?\])*
Then extract second group from all the captures (depending on your langauge)
