I need quick help with regex I have
'http://127.0.0.1:5000/register'
and want to replace it with
`${process.env.API_URL}/register`
doing this regex:
'http://127.0.0.1:5000/.*'
takes the whole thing
Use a capture group to copy the part after /
Find: 'http://127.0.0.1:5000/(.*)'

How to end regex on first search [duplicate]

My regex is matching too much. How do I make it stop? [duplicate]

Closed 4 years ago.
I have the following string:
<center>DB Results:</center><center><b><br>ripster.ultima</b></center><center><b><br>raghav.jhavar</b></center></center></td></tr></table>
I want to extract "ripster.ultima" and "raghav.jhavar", so I used the following regex:
(?<=<center><b><br>)(.*)(?=<\/b><\/center>)
Now, this works in some cases, but not in all: https://regex101.com/r/imO8A8/4
In the link above, the first example is a single line. When I put in a single line, it does not select the individual strings. However, if its separated by a new line as seen in the second example, the strings I want are highlighted.
How do I get the strings in the first example?
You don’t need to group the first and the last patterns
<center><b><br>(.*?)<\/b><\/center>
