Import-Clixml
Imports a CLIXML file and creates corresponding objects in PowerShell.
Syntax
Import-Clixml
[-Path] <String[]>
[-IncludeTotalCount]
[-Skip <UInt64>]
[-First <UInt64>]
[<CommonParameters>]Import-Clixml
-LiteralPath <String[]>
[-IncludeTotalCount]
[-Skip <UInt64>]
[-First <UInt64>]
[<CommonParameters>]Description
The Import-Clixml cmdlet imports objects that have been serialized into a Common Language
Infrastructure (CLI) XML file. A valuable use of Import-Clixml on Windows computers is to import
credentials and secure strings that were exported as secure XML using Export-Clixml.
Example #2 shows how to use Import-Clixml to
import a secure credential object.
The CLIXML data is deserialized back into PowerShell objects. However, the deserialized objects aren't a live objects. They are a snapshot of the objects at the time of serialization. The deserialized objects include properties but no methods.
The TypeNames property contains the original type name prefixed with Deserialized.
Example #3 show the
TypeNames property of a deserialized object.
Import-Clixml uses the byte-order-mark (BOM) to detect the encoding format of the file. If the
file has no BOM, it assumes the encoding is UTF8.
For more information about CLI, see Language independence.
Examples
Example 1: Import a serialized file and recreate an object
This example uses the Export-Clixml cmdlet to save a serialized copy of the process information
returned by Get-Process. Import-Clixml retrieves the serialized file's contents and recreates an
object that is stored in the $Processes variable.
Get-Process | Export-Clixml -Path .\pi.xml
$Processes = Import-Clixml -Path .\pi.xmlExample 2: Import a secure credential object
In this example, given a credential that you've stored in the $Credential variable by running the
Get-Credential cmdlet, you can run the Export-Clixml cmdlet to save the credential to disk.
Important
Export-Clixml only exports encrypted credentials on Windows. On non-Windows operating systems
such as macOS and Linux, credentials are exported in plain text.
$Credxmlpath = Join-Path (Split-Path $Profile) TestScript.ps1.credential
$Credential | Export-Clixml $Credxmlpath
$Credxmlpath = Join-Path (Split-Path $Profile) TestScript.ps1.credential
$Credential = Import-Clixml $CredxmlpathThe Export-Clixml cmdlet encrypts credential objects by using the Windows
Data Protection API. The encryption ensures
that only your user account can decrypt the contents of the credential object. The exported CLIXML
file can't be used on a different computer or by a different user.
In the example, the file in which the credential is stored is represented by
TestScript.ps1.credential. Replace TestScript with the name of the script with which you're
loading the credential.
You send the credential object down the pipeline to Export-Clixml, and save it to the path,
$Credxmlpath, that you specified in the first command.
To import the credential automatically into your script, run the final two commands. Run
Import-Clixml to import the secured credential object into your script. This import eliminates the
risk of exposing plain-text passwords in your script.
Example 3: Inspect the TypeNames property of a deserialized object
This example shows importing an object stored as CLIXML data. The data is deserialized back into a PowerShell object. However, the deserialized object aren't a live objects. They are a snapshot of the objects at the time of serialization. The deserialized objects include properties but no methods.
$original = [pscustomobject] @{
Timestamp = Get-Date
Label = 'Meeting event'
}
$original | Add-Member -MemberType ScriptMethod -Name GetDisplay -Value {
'{0:yyyy-MM-dd HH:mm} {1}' -f $this.Timestamp, $this.Label
}
$original | Get-Member -MemberType ScriptMethod
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
Label NoteProperty string Label=Meeting event
Timestamp NoteProperty System.DateTime Timestamp=1/31/2024 2:27:59 PM
GetDisplay ScriptMethod System.Object GetDisplay();
$original | Export-Clixml -Path event.clixml
$deserialized = Import-CliXml -Path event.clixml
$deserialized | Get-Member

GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
Label NoteProperty string Label=Meeting event
Timestamp NoteProperty System.DateTime Timestamp=1/31/2024 2:27:59 PMNote that the type of the object in $original is System.Management.Automation.PSCustomObject,
but the type of the object in $deserialized is
Deserialized.System.Management.Automation.PSCustomObject. Also, the GetDisplay() method is
missing from the deserialized object.
Parameters
-First
Gets only the specified number of objects. Enter the number of objects to get.
| Type: | UInt64 |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-IncludeTotalCount
Reports the total number of objects in the data set followed by the selected objects. If the cmdlet
can't determine the total count, it displays Unknown total count. The integer has an
Accuracy property that indicates the reliability of the total count value. The value of
Accuracy ranges from 0.0 to 1.0 where 0.0 means that the cmdlet couldn't count the
objects, 1.0 means that the count is exact, and a value between 0.0 and 1.0 indicates an
increasingly reliable estimate.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-LiteralPath
Specifies the path to the XML files. Unlike Path, the value of the LiteralPath parameter is used exactly as it's typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.
| Type: | String[] |
| Aliases: | PSPath, LP |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Path
Specifies the path to the XML files.
| Type: | String[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Skip
Ignores the specified number of objects and then gets the remaining objects. Enter the number of objects to skip.
| Type: | UInt64 |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
Inputs
You can pipe a string containing a path to this cmdlet.
Outputs
This cmdlet returns objects that were deserialized from the stored XML files.
Notes
When specifying multiple values for a parameter, use commas to separate the values. For example,
<parameter-name> <value1>, <value2>.
