Escaping for path with powershell

I have started to make the plunge into converting our VBS to Powershell scripts and have had pretty good luck so far..

However, I am running into an issue with our Apache Log detection script.  It works great under VBS, but Powershell does a great replacement, but still doubles the path..

For example: d:\\logs\\some_server.log  and I need this to be parsed as: d:\logs\some_server.log

$tomcat = Get-Service tomcat* | select -Expand name
Write-Host $tomcat

$description=Get-wmiobject win32_service | where-object {$_.name -match $tomcat} | Foreach-Object {$_.Description}
$PathName=Get-wmiobject win32_service | where-object {$_.name -match $tomcat} | Foreach-Object {$_.PathName}

$TomcatVer = $description.split(" ")[2]
$TomcatPath = $PathName.Substring(0,$PathName.lastindexofany("\bin\")-3)

Write-Host $TomcatVer
Write-Host $TomcatPath

$Serverxml = $TomcatPath + "conf\server.xml"
Write-Host $Serverxml

$sxmls = Get-Content $Serverxml #-encoding String
foreach ($sxml in $sxmls)
{
If ($sxml.contains("appBase"))
{
$LogPath = $sxml.split("=")[1]
$LogPath =$LogPath.Split(" ")[0]
$LogPath = $LogPath -replace([Char](34), "")
}
}

$FL = $LogPath + "\some_server\WEB-INF\classes\log4j.properties"
If ($TomcatVer = "6.0")
{
$LogPath = $TomcatPath + "\webapps\OurApplication"
$FL = $LogPath + "\WEB-INF\classes\log4j.properties"
}

$FLSs = Get-Content $FL
foreach ($FLS in $FLSs)
{
If ($FLS.contains("log4j.appender.LOGFILE.File"))
{
$LogPath = $FLS.Split("=")[1]
$LogPath = $LogPath.Trim()
If ($LogPath.contains("\\"))
{
Write-Host "LogPath "$LogPath
$Separator = [Char](92)+[Char](92)
Write-Host "Separator "$Separator
# Did find: http://stackoverflow.com/questions/548060/replacing-escape-characters-in-powershell
#-replace '\\\\(\w+)\\(\w+)\$', '$1'
$NewLogPath=$LogPath -replace ('\\(.)\1', "\")
Write-Host "first "$NewLogPath
##Still Shows: first  d:\\logs\\aa_server.log
}
If ($LogPath.contains("/"))
{
Write-Host "LogPath "$LogPath
$Separator = "/"
Write-Host "Separator "$Separator
$NewLogPath=$LogPath -replace ($Separator, "\")
Write-Host "second "$NewLogPath
}
}
}

Your usage of lastindexofany in line 8 is wrong. That methods checks for the occurance of ANY of the characters you provide, not of a substring. It will search for '\', 'b', 'i', or 'n'.
But that is not the issue.

I would use -replace '\\\\', '\' for removing the double backslashes.

Very cool!  I know I read about doubling up the slashes, but I had to get it in front of me again..  Also, a good solution in the sense you don't have to use RegEXP...

$LogPath = "d:\\logs\\some_server.log"
$LogPath.replace('\\','\')

Should also work..

Of course that should also work.
[String]::Replace does not use RegExp, hence no escaping necessary.
-replace uses RegExp, and '\' is a special character needing escaping.
