Regex Expressions for value extraction from URL param string

Question

I have a string where I'd like to extract some values with regex.

Whole string:

event=B:Rel&time=1511879856&date=20171128-143736&ref=57b3e1ab741d5a017ab8009033350b18&dir=out&src_if=GW1&dst_if=PRI1

I would like to isolate the values between the = and the next & creating this result set for the string given above.

B:Rel
1511879856
20171128-143736
57b3e1ab741d5a017ab8009033350b18
out
GW1
PRI1

Thanks for the help!

This way the matches would contain = and & You should try non-capturing groups: stackoverflow.com/questions/36619162/… — Björn

It seems to be a query string. What language are you using? Probably there is an easier way to do what you need. Also, why do you want those values in a single string? — Washington Guedes

Try this:

[^=]+=([^&]+)(?:&|$)

Depending on your language, you could split the input on this regex:

&?[^=]*=
