PowerShell: cannot pipe output to file in combination with -Outputformat XML and -File

Question

Script file c:/chgpwd.ps1

Param(
    [parameter(Mandatory=$true)]
    [string] $user,
    [parameter(Mandatory=$true)]
    [string] $oldPass,
    [parameter(Mandatory=$true)]
    [string] $newPass
)
write-host "before"
$Computername = $env:COMPUTERNAME
([adsi]"WinNT://$Computername/$user").ChangePassword("$oldPass", "$newPass")
write-host "after"

When executing this via

powershell -OutputFormat XML -ExecutionPolicy bypass -File c:\chgpwd.ps1 'myuser' 'a' 'b' 2>&1 > C:\out.xml

Note: the user exists but its new password (b) does not match the password policy

the output file (C:\out.xml) won't contain any xml, but the xml will be shown in the console out.

For now I only get the content (out.xml)

powershell : Exception calling "ChangePassword" with "2" argument(s): "The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements. " At line:1 char:1 + powershell -OutputFormat XML -ExecutionPolicy bypass -File C:\chgpwd.ps1 ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo> > : NotSpecified: (:) [chgpwd.ps1], MethodInvocationException + FullyQualifiedErrorId : CatchFromBaseAdapterMethodInvokeTI,chgpwd.ps1.ps1

Is there a way I get the xml ouput in the file?

I would have expected the xml which is rendered to the console out to be in the out file (if piped). For parsing the error message xml would be better. — tobi

i have not used the -OutputFormat switch before, but you may be able to use export-clixml

try {
    1/0
} catch {
    $_ | Export-Clixml C:\temp\text.xml
    start C:\temp\text.xml
}

Thanks for the quick answer: I tried this and it works fine, but in case of a syntax error in the script this won't help or if a required parameter is missing or if it cannot find the file. Especially in my case the script comes from third party.
