I just want to regurgitate this in my own words to make sure I'm grasping this
concept.
I can create an outer loop (e.g. ":Outerloop") inside the Process{} block. Then
if the Validate-Name fails I can instead execute a "Break :Outerloop" to end
that object's processing, but the Process{} block will continue executing on
additional objects being passed through the pipeline. So in essence you're
defining the scope of the break. Right?

If you do a break in the outer loop (or mainline) of a process{} block, you
will exit the process block.
Using a named break or continue is a good solution with low overhead.

Here is something MBS showed me a little while ago. See if it might give you an
idea.
Function GetBadStreamingIPAddresses
{
Param([string]$ComputerName)
#loop through the configured streaming ip address and compare
to the physical configured ip addresses
#if a streaming ip address is not in the list of physical ip
addresses, it is a bad streaming ip address
ForEach ($Stream in ($Script:StreamingIPAddresses | Where
{$_.Servername -eq $ComputerName})) {
$exists = $false
:outerLoop ForEach ($ServerNIC in
$Script:NICIPAddresses.Item($ComputerName))
{
ForEach ($IP in $ServerNIC)
{
# there could be
more than one IP
If
($Stream.IPAddress -eq $IP)
{
$Exists = $true
break :outerLoop
}
}
}
if (!$exists)
{
$obj1 = New-Object -TypeName
PSObject
$obj1 | Add-Member -MemberType
NoteProperty -Name ServerName -Value $ComputerName
$obj1 | Add-Member -MemberType
NoteProperty -Name IPAddress -Value $Stream.IPAddress
$Script:BadIPs += $obj1
}
}
}

Subject: [powershell] Breaking Process { } Block:
I am doing some testing and not sure the best way to accomplish the desired
outcome.
I have a script with several functions. One advanced function will take a CSV
file and generate AD users. I have a sub-function to validate names:
function Validate-Name ([string]$field) {
if ($field -notmatch "[^\p{L}^\p{Pd}\s/']") {
return $false
} else {
return $true
}
}
During the Process{} block, I'd like to attempt to validate the first/last name
and bail out for just the one user and continue attempting for any subsequent
entries in the CSV file. My main question is there a best practice, or agreed
general guideline for handling this? Do you wrap everything in an If statement
before proceeding? Or do you have a Break/Return/Exit within the process block?
I thought Exit/Return/Break end the entire function, but reading up I'm not
sure if using Break to exit the Process{} block would also exit the parent
function. I'm interested in how others handle this.
I'd like to be able to break out of processing that one row, then continue
processing the CSV file:
Process {
If (Validate-Name $FirstName) {
# Log failure (TBD)
Break
}
}
Process {
If (Validate-Name $FirstName) {
# Log failure (TBD)
Exit
}
}
Process {
If (Validate-Name $FirstName) {
$failed = $true
}
If ($failed) {
# Log failure (TBD)
} Else {
#Process user Add
}
}
