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)

The program contains text of this type:
A B Ccccc
A Ccccc
ACcccc
ABCcccc
I need only such text to remain:
Ccccc
I wrote a replacement function, but I just can’t pick up a pattern
How to make such a pattern?

No need for regex, nor VBA. It seems you simply are looking for the position of the last upper-case letter and then to extract from there:
Formula in B1 (with Excel O365):
=MID(A1,MAX(SEQUENCE(LEN(A1))*(EXACT(UPPER(MID(A1,SEQUENCE(LEN(A1)),1)),MID(A1,SEQUENCE(LEN(A1)),1)))),LEN(A1))
If you don't have Excel O365:
=MID(A1,MAX(ROW(A1:INDEX(A:A,LEN(A1)))*(EXACT(UPPER(MID(A1,ROW(A1:INDEX(A:A,LEN(A1))),1)),MID(A1,ROW(A1:INDEX(A:A,LEN(A1))),1)))),LEN(A1))
You probably need to enter as array through: CtrlShiftEnter
If you must go through VBA and regex then a pattern like:
[A-Z][^A-Z]*$

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 would like to search for everything before the string http://thepaperwall.com/wallpapers/ but not including that string.
I would also like to search for everything after .jpg but not including .jpg.
So my final string should look like this:
http://thepaperwall.com/wallpapers/cityscape/small/small_642331afcd78d0840485bb352d99b289b50e8467.jpg
How can I do this?

You can use look-behind and look-ahead to get a string position between 2 other strings:
(?<=http://thepaperwall.com/wallpapers/).*(?=\.jpg)

You need a non-capturing group:
(.*)(?:http:\/\/thepaperwall\.com\/wallpapers\/.*\.jpg)(.*)

i want to parse the values between -. but for some data like 1st url contains -- so in that case i need to get the gap only and the next one i am able to get **camry** successfully by using *(site_data,'[^-]+',1,2)*. but i want to handle the gap as well.

Please help on this.

You can extract the string along with the hyphens, and then trim the hyphens.
trim('-' from regexp_substr(site_data,'-[^-]*-'))
Alternatively, you can also use regexp_replace function.
regexp_replace(site_data,'(-([^-]*)-)|(.)','\2')

How do you find the first word after a string literal via regex?
I.e.
I want to extract "DAQJ7PS" from the line:
ERROR service.PostService - Failed to save post DAQJ7PS

/ERROR service\.PostService - Failed to save post (.+)/
will give you the result in the first capturing group. This can be tuned if you have more specific requirements.
