How to fix the regex pattern for splitting string

Question

I need to separate comparison operators (==, !=, >, <, >=, <=) from the string value.

I can have following possible combinations

== 1
== 100.24
== 120/numberOfRows
<= 1/3
>= 2232

I tried below regex pattern but it not working as expected.

    Pattern = "(<[=>]?|==|=<|=>|>=?|\\&\\&|\\|\\|) (\\w*\\.?\\w+\\.?\\/?\\w+)".r

Why not just """(<[=>]?|=[<>=]|>=?|!=|&&|\|\|)\s+(.+)""".r? — Wiktor Stribiżew

You can use

"""(<[=>]?|=[<>=]|>=?|!=|&&|\|\|)\s+(.+)""".r

See the regex demo. Details:

(<[=>]?|=[<>=]|>=?|!=|&&|\|\|) - <, <=, <>, =<, =<, =>, ==, >, >=, !=, && or ||
\s+ - 1+ whitespaces
(.+) - Group 2: any one or more chars, other than line break chars, as many as possible.
