Regex: Match everything between characters or new line

I am trying to come up with a regex that would identify instances of abc=123456|123456 from the following snippet:

xyz=abcdef|abcdef||abc=123456|123456||cat=dog|dog||foo=bar|bar||
xyz=abcdef|abcdef||abc=123456|123456
xyz=abcdef|abcdef||abc=123456|123456||
abc=123456|123456||xyz=abcdef|abcdef||

The requirement here is that the match string can have a trailing double pipe or it could not have it.

I am currently using this:

/abc=(.*?)+((?=\|\|)|(?=\r|\n))/

But this seems to break with the OR condition for end of match.

Appreciate any help in advance.

You may use end of the line anchor instead of \r or \n and you have to remove the + which exists just after to (.*?). With +, it does a greedy match and the capturing group must contain an empty string.

\babc=(.*?)(?=\|\||$)

or

\babc=(.*?)(?=\|\||\r|\n)
