Replace query string with regular expression?

Question

I have a query string parameter looks like below:

Nr=AND(OR(abc:def),OR(ghi:jkl),OR(mno:pqr).....so on)

I wanted to replace this query string to get the values inside the OR condition delimited between colon.

any help will be appreciated.!!

Answer 1

The below regex would capture the text inside OR function and stored it into two separate groups using : as delimiter,

OR\(([^:]*):([^)]*)\)

Explanation:

• OR\\( Matches literal OR( .

• ([^:]*) NOt of : character zero or more times. Finally it stores the matched characters into group1.

• : A literal :

• ([^)]*) Not of a literal ) character zero or more times. Finally it stores the matched characters into group2.

• \\) Matches a literal ) character.
