How to import a ConvertFrom-String TemplateContent from file with PowerShell? - string

Question

Creating the file from the console:
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> #'
>> UserPrincipalName : {UserPrincipalName*:LeeG#lazydev.com}
>> DisplayName : {DisplayName:Lee Gu}
>> Title : {Title:jr engineer}
>> UserType : {UserType:Member}
>> IsLicensed : {IsLicensed:True}
>>
>> UserPrincipalName : {UserPrincipalName*:MeganB#lazydev.com}
>> '# | Out-File full_template.psd1
PS /home/nicholas/powershell>
PS /home/nicholas/powershell> cat ./full_template.psd1
UserPrincipalName : {UserPrincipalName*:LeeG#lazydev.com}
DisplayName : {DisplayName:Lee Gu}
Title : {Title:jr engineer}
UserType : {UserType:Member}
IsLicensed : {IsLicensed:True}
UserPrincipalName : {UserPrincipalName*:MeganB#lazydev.com}
PS /home/nicholas/powershell>
but how is that file data imported?
This looks to be a "here string" but the usage, in particular, of the colon isn't clear from the documention I've referenced on data files for PowerShell.

Answer 1

I used a string as input with code below for testing
$properties = #"
UserPrincipalName : {UserPrincipalName*:LeeG#lazydev.com}
DisplayName : {DisplayName:Lee Gu}
Title : {Title:jr engineer}
UserType : {UserType:Member}
IsLicensed : {IsLicensed:True}
"#
$reader = [System.IO.StringReader]::new($properties)
$table = [System.Collections.ArrayList]::new()
$pattern = "\{(?<name>[^:]+):(?<value>[^}]+)"
while(($line = $reader.ReadLine()) -ne $null)
{
$match = $line | Select-String -Pattern $pattern
$name = $match.Matches.groups['name'].value
$value = $match.Matches.groups['value'].value
$newRow = New-Object -TypeName psobject
$newRow | Add-Member -NotePropertyName Name -NotePropertyValue $name
$newRow | Add-Member -NotePropertyName Value -NotePropertyValue $value
$table.Add($newRow) | Out-Null
}
$table
From a file
$input_filename = "c:\temp\test.txt"
$pattern = '\{(?<name>[^:]+):(?<value>[^}]+)'
$match = Select-String -Path $input_filename -Pattern $pattern
$table = [System.Collections.ArrayList]::new()
$newRow = New-Object -TypeName psobject
foreach($row in $match.Matches)
{
$name = $row.groups[1].value
$value = $row.groups[2].value
Write-Host "name = " $name "value = " $value
$newRow | Add-Member -NotePropertyName $name -NotePropertyValue $value
}
$table.Add($newRow) | Out-Null
$table | Format-Table
