ConvertFrom-String

Another way to parse log files is to use the ConvertFrom-String cmdlet, with which you can create a pattern file. You can easily extract two lines from your log file and replace the desired values with {%Name%:%Value%}. The following example demonstrates this approach for the dism.log log file:

#Reading content of log file - last 50 lines
$targetData = Get-Content C:\Windows\Logs\DISM\dism.log -Tail 50

#2 example lines of code - replaced pattern values with {%Name%:%Value%}
$TemplateContent = @'
