Я бы немного изменил регулярное выражение, потому что смешивать именованные захваты с нумерованными захватами не рекомендуется, поэтому оно становится таким:
'^\{(?<type>[a-z]+)(?:-\[(?<target>[CF]{1,2})\])?(?:\[(?<tab>\d+)\])?\}_(?<string>.*)'
Затем вы можете использовать его, как показано ниже, для замены значения tab
:
$line = '{initError-[cf][3]}_Invalid nodes(s): [3]'
$newTabValue = 12345
$line -replace '^\{(?<type>[a-z]+)(?:-\[(?<target>[CF]{1,2})\])?(?:\[(?<tab>\d+)\])?\}_(?<string>.*)', "{`${type}-[`${target}][$newTabValue]}_`${string}"
Результатом будет:
{initError-[cf][12345]}_Invalid nodes(s): [3]
Детали регулярного выражения:
^ Assert position at the beginning of the string
\{ Match the character “{” literally
(?<type> Match the regular expression below and capture its match into backreference with name “type”
[a-z] Match a single character in the range between “a” and “z”
+ Between one and unlimited times, as many times as possible, giving back as needed (greedy)
)
(?: Match the regular expression below
- Match the character “-” literally
\[ Match the character “[” literally
(?<target> Match the regular expression below and capture its match into backreference with name “target”
[CF] Match a single character present in the list “CF”
{1,2} Between one and 2 times, as many times as possible, giving back as needed (greedy)
)
\] Match the character “]” literally
)? Between zero and one times, as many times as possible, giving back as needed (greedy)
(?: Match the regular expression below
\[ Match the character “[” literally
(?<tab> Match the regular expression below and capture its match into backreference with name “tab”
\d Match a single digit 0..9
+ Between one and unlimited times, as many times as possible, giving back as needed (greedy)
)
\] Match the character “]” literally
)? Between zero and one times, as many times as possible, giving back as needed (greedy)
\} Match the character “}” literally
_ Match the character “_” literally
(?<string> Match the regular expression below and capture its match into backreference with name “string”
. Match any single character that is not a line break character
* Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
