正则表达式组名称值包含 2 个以上的单词

  • 772

这段代码运行良好

$pop = New-Object -ComObject wscript.shell
$string = "John Adams, Age: 204, Email: [email protected]"
# Regular expression pattern with named groups
$regex = '(?<Name>\w+\s\w+),\sAge:\s(?<Age>\d+),\sEmail:\s(?<Email>[^\s]+)'
# Apply the regex match
if ($string -match $regex) {
    # Access the groups using automatic variable $matches
    $name = $matches['Name']
    $age = $matches['Age']
    $email = $matches['Email']
    $pop.popup("Name: $name`nAge: $age`nEmail: $email",5,"Success",4096)
} else {
    $pop.popup("No Matches found.",4,"Oh Oh",4096)
}
Exit

但是如果我将字符串改为以 John Quincey Adams 开头，名称组只会返回 Quincey Adams。我知道可以添加一个额外的 \w+\s，但是有没有办法以通用的方式将任意数量的单词名称捕获到组中？

    (?:\s\w+)*您可以在捕获组中添加一个可选的非捕获组Name，请参阅：https://regex101.com/r/itimND/1。

    $pop = New-Object -ComObject wscript.shell
$string = 'John Quincey Adams, Age: 204, Email: [email protected]'
# Regular expression pattern with named groups
$regex = '^(?<Name>\w+\s\w+(?:\s\w+)*),\sAge:\s(?<Age>\d+),\sEmail:\s(?<Email>[^\s]+)'
# Apply the regex match
if ($string -match $regex) {
    # Access the groups using automatic variable $matches
    $name = $matches['Name']
    $age = $matches['Age']
    $email = $matches['Email']
    $pop.popup("Name: $name`nAge: $age`nEmail: $email", 5, 'Success', 4096)
}
else {
    $pop.popup('No Matches found.', 4, 'Oh Oh', 4096)
}

    也许如果通过拆分来解析字符串会更容易：

    $pop = New-Object -ComObject wscript.shell
$string = 'John Quincey Adams, Age: 204, Email: [email protected]'
$name, $age, $email = $string -split ',\s*'
$pop.popup("Name: $name`n$age`n$email", 5, 'Success', 4096)
