search for certian words in a string - regex

Question

I´m struggling in a simple report script.
for example
$report.FullFormattedMessage = "This is the deployment test for Servername for Stackoverflow in datacenter onTV"
$report.FullFormattedMessage.GetType()
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True String System.Object
Now I want to pick some certians words out like...
$dc = should be the 'onTV'
$srv = should be the 'Servername'
$srv = $report.FullFormattedMessage.contains... or -match ?? something like this?
The trick with .split()[] is not working for me because the $report looks different some times. How could I do that?

Answer 1

oh ok I found a solution, I dont know if this is best... but I show you:
$lines = $report.FullFormattedMessage.split()
$dc= ForEach ($line in $lines){
$line | Where-Object {$_ -match "onTV*"}
}
$srv= ForEach ($line in $lines){
$line | Where-Object {$_ -match "Server*"}
}

Answer 2

I'd probably do something like
$report.FullFormattedMessage = "This is the deployment test for Servername for Stackoverflow in datacenter onTV"
$dc = if ($report.FullFormattedMessage -match '\b(onTV)\b') { $Matches[1] } # see details 1
$srv = if ($report.FullFormattedMessage -match '\b(Server[\w]*)') { $Matches[1] } # see details 2
# $dc --> "onTV"
# $srv --> "Servername"
Regex details 1
\b Assert position at a word boundary
( Match the regular expression below and capture its match into backreference number 1
onTV Match the characters “onTV” literally
)
\b Assert position at a word boundary

\b Assert position at a word boundary

Server Match the characters “Server” literally
[\w] Match a single character that is a “word character” (letters, digits, etc.)
