PowerShell - HTML parsing: get information from a website

Question

Update, Script is working with PowerShell V3.0, Thanks @ Doug

I want to use the following PowerShell script to get flight status information from Lufthansa. I can see flight status information in the browser, but I haven't found any way to access this information with my script.

I want to get the following information from the website:

• flight status
• time (departure, arrival)
• airport (departure, arrival)
• Flight Number (Only Lufthansa)

Script:

$flight = " LH3396" $url = "http://bing.com?q=flight status for $flight" $result = Invoke-WebRequest $url $elements = $result.AllElements | Where Class -eq "ans" | Select -First 1 -ExpandProperty innerText   #[string[]]$resultArray  $resultArray = @()  foreach($element in $elements.Split("`n")){     if($element.Length -gt "2")     {$resultArray += $element} }
