Are SharePoint Designer Workflows Using Custom Features or Solutions (iLoveSharePoint)

Needed to audit a farm to see if a CodePlex solution was being used in SharePoint Designer workflows.  In my case, I needed to see where the iLove SharePoint  solution was being used. The script below is only targeted at one web and is looking for word “ILoveSharePoint” in the XML.

#load the SP snapin....
Function GetFiles($folder)
{ 
   foreach($file in $folder.Files)
   {
	   if($file.Name.Split('.')[-1] -eq "xoml")
	   {	
	   		$web2 = Get-SPWeb $file.Web.Url
			$wFile = $web2.GetFileOrFolderObject($web2.URL +"/"+ $file.URL)
		
		if ($wFile.Exists -eq "True")
		{
			1$wXml = (New-Object System.Text.UTF8Encoding).GetString($wFile.OpenBinary());
			if($wXml.RootWorkflowActivityWithData.ns0.Contains("ILoveSharePoint"))
			{
				Write-Host $folder
			}
		} 
	   }   
	}

   # Use recursion to loop through all subfolders.
   foreach ($subFolder in $folder.SubFolders)
   {
       Write-Host "`t" -NoNewline
       GetFiles($Subfolder)
   }
 }

$web1 = Get-SPWeb "http://SomeWebURL"
$list1 = $web1.Lists["Workflows"]

GetFiles($list1.RootFolder)
