匹配时，一个单词优先于另一个单词吗？

Question

I have the following list.

ID    AllStatuses
1001  {failed|processing|success}
1002  {failed}
1003  {success|failed}
1004  {processing|success}
1005  {failed|processing}

My requirement is to display the most optimistic status alone. Like so

ID    Best Status
1001  success
1002  failed
1003  success
1004  success
1005  processing

Is there a way I can do this with one regex query rather than say check for each one in order and return where i'd have a worst case scenario of three regex checks for statuses with the most optimistic status in the end?

Answer 1

Regex: \{.*(success).*|\{.*(processing).*|\{.*(failed).* Substitution: $1$2$3

Details:

• .* matches any character zero or more times
• () Capturing group
• | Or

Go code:

var re = regexp.MustCompile(`\{.*(success).*|\{.*(processing).*|\{.*(failed).*`)
s := re.ReplaceAllString(sample, `$1$2$3`)

Output:

ID    AllStatuses
1001  success
1002  failed
1003  success
1004  success
1005  processing
