Reading zip archive files for content - powershell

Question

I created the following code, but it is not actually reading any of the .zip or .prd files as expected, but the other parts are working. Might you help me figure out why it is not actually reading the zip files in the ForEach loop?
#Set variables for subversion paths
$ScriptPath = (Split-Path $myinvocation.MyCommand.path -Parent)
#$Package = $ScriptPath
#Create folder for temporary copy of SVN directory
New-Item C:\MyTemp-type directory -ErrorAction SilentlyContinue -Force
New-Item C:\Results -type directory -ErrorAction SilentlyContinue -Force
Test-Path $profile
New-item –type file –force $profile
#Set variables for subversion paths
$CurrentSVNPath = "http://MySVNPath"
$TempSVNPath = "C:\MyTemp"
$ResultsFilePath = "C:\Results"
#Download a local copy of the SVN Repository
# Wait for command to finish before moving forward
#$SVNDownloadJob = Start-Job {SVN Checkout $CurrentSVNPath $TempSVNPath}
$SVNDownloadJob = Start-Job {TortoiseProc.exe /command:update /path:"C:\SVN_Repo" /closeonend:1 | Out-Null}
Wait-Job $SVNDownloadJob
Receive-Job $SVNDownloadJob
#Find pattern to search for within all files from where this script is run
#If you do not want to look for the standard pattern uncomment/comment the $Pattern variables
#$Pattern = Read-Host 'What pattern are you looing for?'
$Pattern = "Simulate=`"true`""
$SearchPattern = “Simulate=`”true`””
$PackageList = Get-ChildItem –Path $ScriptPath –Recurse –filter “*.zip, *.prd”
#Start searching all folders where this script exists for 'Simulate=true'
$k =foreach ($file in Get-ChildItem -Path $ScriptPath -Recurse | Select-String -pattern $Pattern | Select-Object -Unique path) {$file.path}
$k > "$($ResultsFilePath)\SimulateEqualsTrueZipFiles.txt"
Foreach ( $Package in $PackageList) {
Read-Archive -$_.Path -Format Zip | `
Where-Object { $_.Name -like "*.zip" } | `
Expand-Archive -PassThru | select-string $SearchPattern | Select-Object -Unique path {$file.path}
$k > "$($ResultsFilePath)\SimulateEqualsTrueZipFiles.txt"
}

You can get the contents of Zip Folder by using below cmdlets
$ZipFile="Path"
$AllFile=Get-ChildItem $ZipFile -Recurse -Filter '*.zip'
$ObjArray = #()
foreach ($item in $AllFile){
$FullName=$item.FullName
$RawFiles = [IO.Compression.ZipFile]::OpenRead($FullName).Entries
$FullPathName=$FullName+"\"+"$RawFile"
foreach($RawFile in $RawFiles) {
$object = New-Object -TypeName PSObject
$Object | Add-Member -MemberType NoteProperty -Name FileName -Value $RawFile.Name
$Object | Add-Member -MemberType NoteProperty -Name FullPath -Value $FullPathName
$Object | Add-Member -MemberType NoteProperty -Name CompressedLengthInKB -Value ($RawFile.CompressedLength/1KB).Tostring("00")
$Object | Add-Member -MemberType NoteProperty -Name UnCompressedLengthInKB -Value ($RawFile.Length/1KB).Tostring("00")
$Object | Add-Member -MemberType NoteProperty -Name FileExtn -Value ([System.IO.Path]::GetExtension($RawFile.FullName))
$Object | Add-Member -MemberType NoteProperty -Name ZipFileName -Value $zipfile
$ObjArray += $Object
}
}
Make sure dot net 4.5 is installed before running the above cmdlets.
