Parse and manipulate HTML Files

What is the best way to load html files from a file system, parse it, manipulate the DOM then save it back to a file?

I am trying following code but is does not seem to work because the type is Microsoft.PowerShell.Commands.WebResponseObject and not the Microsoft.PowerShell.Commands.HtmlWebResponseObject which provides for the $html.ParsedHtml property.

$uri = “C:\temp\EventLog.html”
$html = Invoke-WebRequest -Uri $uri
$html | Get-Member

I could be wrong but I don’t think that Invoke-Webrequest will have access to the dom. you may have to use

$ie = new-object -ComObject “InternetExplorer.Application”
$uri = “C:\temp\EventLog.html”
$result = $ie.document.body # depending on what you wanted to get to.

and don’t forget to kill the ii session when you have finished.
