How to use regexp to extract the digit within { customer:490 } bought a car { car:6441 }

Question

I have a json object with value in this pattern: { customer:1501 } bought a car { car:6333 } How to use regexp to extract the digit of customer and car. I am very new to regex, I can only extract the string between the curly braces. I am not sure should I do it separately, i.e. extract the string between the curly braces than extract the digits after "customer:" or "car:". Please help

You can use this regex to match the curly braces and match customer or car and then the digits, and capture your digits from group1,

{\s*(?:customer|car):(\d+)\s*}

Explanation of regex:

{ - Match a literal {
\s* - Match optional whitespace
(?:customer|car): - Match either customer or car literally followed by a colon
(\d+) - Matched one or more digits and capture it in group1
\s*} - Match optional space then closing curly bracket }
