Powershell - Regular Expression Multiple Matches

Question

Maybe my reasoning is faulty, but I can\'t get this working.

Here\'s my regex: (Device\\s#\\d(\\n.*)*?(?=\\n\\s*Device\\s#|\\Z))

Try it: http://

Answer 1

With your existing regex, to get a list of all matches in a string, use one of these options:

Option 1

$regex = [regex] '(Device\s#\d(\n.*)*?(?=\n\s*Device\s#|\Z))'
$allmatches = $regex.Matches($yourString);
if ($allmatches.Count > 0) {
    # Get the individual matches with $allmatches.Item[]
} else {
    # Nah, no match
} 

Option 2

$resultlist = new-object System.Collections.Specialized.StringCollection
$regex = [regex] '(Device\s#\d(\n.*)*?(?=\n\s*Device\s#|\Z))'
$match = $regex.Match($yourString)
while ($match.Success) {
    $resultlist.Add($match.Value) | out-null
    $match = $match.NextMatch()
}
