How to capture multiple regex matches, from a single line, into the $matches magic variable in Powershell?

You can do this using Select-String in PowerShell 2.0 like so:

Select-String F\d\d -input $string -AllMatches | Foreach {$_.matches}

A while back I had asked for a -matchall operator on MS Connect and this suggestion was closed as fixed with this comment:

"This is fixed with -allmatches parameter for select-string."

I suggest using this syntax as makes it easier to handle your array of matches:

$string = "blah blah F12 blah blah F32 blah blah blah" ;$matches = ([regex]'F\d\d').Matches($string);$matches[1].Value; # get matching value for second occurance, F32

I see 2 scenarios that are handled differently:

1. extracting all matches of a single pattern
2. extracting single match of multiple patterns

1. extract all matches of one pattern: select-string + -allmatches

• e.g. regex: (?<=jobs).*
• counter-intuitive but you need to use Select-String to handle this like I am to get ids of nomad jobs from the output exemplified below

$m = "Watch the deployment in realtime at: https://nomad.foo.net/ui/jobs/20e183af-8243-11eb-a2af-0a58a9feac2a08:23Watch the deployment in realtime at: https://nomad.foo.net/ui/jobs/20e130e9-8243-11eb-a2af-0a58a9feac2a"$r = "(?<=jobs/).*"$l = Select-String $r -InputObject $m -AllMatches |     Foreach {$_.matches.Value}20e183af-8243-11eb-a2af-0a58a9feac2a20e130e9-8243-11eb-a2af-0a58a9feac2a$l[0]>>> 20e183af-8243-11eb-a2af-0a58a9feac2a

2. extract a single/first match of one/multiple patterns: capture groups and $Match[]

▶ $s = "Hello World from Mr Pavol"▶ $r = "(World).*(Pavol)"▶ $s -match $rTrue▶ $MatchesName                           Value----                           -----2                              Pavol1                              World0                              World from Mr Pavol
