Parsing robocopy log file to PSCustomObject - parsing

Question

I'm trying to create a PSCustomObject from a robocopy log file. The first piece is pretty easy but I'm struggling with the $Footer part. I can't seem to find a good way to split up the values.
It would be nice if every entry has it's own Property, so it's possible to use for example $Total.Dirs or $Skipped.Dirs. I was thinking about Import-CSV, because that's just great on how it allows you to have column headers. But this doesn't seem to fit here. There's another solution I found here but it seems a bit of overkill.
Code:
Function ConvertFrom-RobocopyLog {
Param (
[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=0)]
[String]$LogFile
)
Process {
$Header = Get-Content $LogFile | select -First 10
$Footer = Get-Content $LogFile | select -Last 7
$Header | ForEach-Object {
if ($_ -like "*Source*") {$Source = (($_.Split(':'))[1]).trim()}
if ($_ -like "*Dest*") {$Destination = (($_.Split(':'))[1]).trim()}
}
$Footer | ForEach-Object {
if ($_ -like "*Dirs*") {$Dirs = (($_.Split(':'))[1]).trim()}
if ($_ -like "*Files*") {$Files = (($_.Split(':'))[1]).trim()}
if ($_ -like "*Times*") {$Times = (($_.Split(':'))[1]).trim()}
}
$Obj = [PSCustomObject]#{
'Source' = $Source
'Destination' = $Destination
'Dirs' = $Dirs
'Files' = $Files
'Times' = $Times
}
Write-Output $Obj
}
}
Log file:

You can clean this up more but this is the basic approach I would take.
Function ConvertFrom-RobocopyLog {
Param (
[Parameter(Mandatory=$true,ValueFromPipelineByPropertyName=$true,Position=0)]
[String]$LogFile
)
Process {
$Header = Get-Content $LogFile | select -First 10
$Footer = Get-Content $LogFile | select -Last 7
$Header | ForEach-Object {
if ($_ -like "*Source*") {$Source = (($_.Split(':'))[1]).trim()}
if ($_ -like "*Dest*") {$Destination = (($_.Split(':'))[1]).trim()}
}
$Footer | ForEach-Object {
if ($_ -like "*Dirs*"){
$lineAsArray = (($_.Split(':')[1]).trim()) -split '\s+'
$Dirs = [pscustomobject][ordered]#{
Total = $lineAsArray[0]
Copied = $lineAsArray[1]
Skipped = $lineAsArray[2]
Mismatch = $lineAsArray[3]
FAILED = $lineAsArray[4]
Extras = $lineAsArray[5]
}
}
if ($_ -like "*Files*"){
$lineAsArray = ($_.Split(':')[1]).trim() -split '\s+'
$Files = [pscustomobject][ordered]#{
Total = $lineAsArray[0]
Copied = $lineAsArray[1]
Skipped = $lineAsArray[2]
Mismatch = $lineAsArray[3]
FAILED = $lineAsArray[4]
Extras = $lineAsArray[5]
}
}
if ($_ -like "*Times*"){
$lineAsArray = ($_.Split(':',2)[1]).trim() -split '\s+'
$Times = [pscustomobject][ordered]#{
Total = $lineAsArray[0]
Copied = $lineAsArray[1]
FAILED = $lineAsArray[2]
Extras = $lineAsArray[3]
}
}
}
$Obj = [PSCustomObject]#{
'Source' = $Source
'Destination' = $Destination
'Dirs' = $Dirs
'Files' = $Files
'Times' = $Times
}
Write-Output $Obj
}
}
I wanted to make a function to parse the footer lines but $Times is a special case since it does not have all the same columns of data.
With $Times the important difference is how we are doing the split. Since the string contains more than one colon we need to account for that. Using the other paramenter in .Split() we specify the number of elements to return.
$_.Split(':',2)[1]
Since these logs always have output and no blanks row elements we can do this assuming that the parsed elements of $lineAsArray will always have 6 elements.
Sample Output
Source : \\SHARE\Source\
Destination : \\SHARE\Target\
Dirs : #{Total=2; Copied=0; Skipped=2; Mismatch=0; FAILED=0; Extras=0}
Files : #{Total=203; Copied=0; Skipped=203; Mismatch=0; FAILED=0; Extras=0}
Times : #{Total=0:00:00; Copied=0:00:00; FAILED=0:00:00; Extras=0:00:00}
So if you wanted the total files copied you can now use dot notation.
(ConvertFrom-RobocopyLog C:\temp\log.log).Files.Total
203

Not that clear what you want to do, but this will go some way to showing you how to get the stats into an array of objects
$statsOut = #()
$stats = Get-Content $LogFile | select -Last 6 | select -first 4
$stats | % {
$s = $_ -split "\s+"
$o = new-object -type pscustomobject -property #{"Name"=$s[0];"Total"=$s[2];"Copied"=$s[3];"Skipped"=$s[4];"mismatch"=$s[5]};
$statsOut += ,$o
}
Gives:
[PS] > $statsOut | ft -Auto
mismatch Name Skipped Total Copied
-------- ---- ------- ----- ------
0 Dirs 2 2 0
0 Files 203 203 0
0 Bytes 0 0 0
