How to avoid false matches when using Powershell hash table keys-CodePudding

The example is:

$testLines = "050 BLACK Michael Douglas 32 Kellogs Court Wondertown Fitter","056 WHITE Brian Dennis 101 Wood Street Wondertown Court Worker"
 
# hash table for linking a street type to the street name using an underscore
$streetTypeHash = @{
    ' Drive ' = '_Drive, ';
    ' Street ' = '_Street, ';
    ' Court Worker ' = ' Court Worker ';  # include any term that may be mistakenly referenced. Ensure it remains unchanged.
    ' Court ' = '_Court, ';
}

# read the street type (e.g Street, Road, Drive, Court etc) & join with underscore to street name
for ($i = 0; $i -lt $testLines.Count; $i  ) {
  foreach ($Key in $streetTypeHash.Keys) {
        if ($testLines[$i] -match $Key) {
          $testLines[$i] = $testLines[$i] -replace $Key, $($streetTypeHash[$Key])  
        }
  }

  $testLines[$i]

The second line of output shows the problem:

050 BLACK Michael Douglas 32 Kellogs_Court, Wondertown Fitter
056 WHITE Brian Dennis 101 Wood_Street, Wondertown_Court, Worker

My understanding is: the first available match is 'Court'. Regardless of whether any other characters are part of the key string. Therefore it is not possible to use this approach to negate false matches. I have tried using another hash table:

$notStreetTypeHash = @{
  ' Court Worker ' = ' Court Worker ';
}

But using the respective keys, of these two hash tables, to find -match & -notMatch was not working.

Any suggestion appreciated.

If I'm understanding correctly, you could just simplify the whole process to:

$testLines = @(
    "050 BLACK Michael Douglas 32 Kellogs Court Wondertown Fitter"
    "056 WHITE Brian Dennis 101 Wood Street Wondertown Court Worker"
)

$testLines -replace '\s(Drive|Street|Court)\s(?!Worker)', '_$1, '
