If not specified, uses default context. .PARAMETER ParentList Indicates the list which the list items are contained. .PARAMETER FolderUrl Indicates the folder URL. .PARAMETER Scope Indicates the scope of retrievals. - FilesOnly: Only the files of a specific folder. - Recursive: All files of all folders. - RecursiveAll: All files and all subfolders of all folders. If not specified, only the files and subfolders of a specific folder. .PARAMETER ViewFields Indicates the collection of view fields. .PARAMETER Query Indicates the XML representation of query. .PARAMETER RowLimit Indicates the number of items. This parameter is used for item pagination. .PARAMETER Position Indicates the starting position. This parameter is used for item pagination. .PARAMETER Identity Indicates the list item ID. .PARAMETER IdentityGuid Indicates the list item GUID. .PARAMETER Retrievals Indicates the data retrieval expression. .EXAMPLE Get-SPClientListItem .EXAMPLE Get-SPClientListItem -Scope "Recursive" -ViewFields "ID", "Title" -Query "<OrderBy><FieldRef Name='Title'/></OrderBy>" -RowLimit 10 .EXAMPLE Get-SPClientListItem -Identity 7 .EXAMPLE Get-SPClientListItem -IdentityGuid "77DF0F67-9B13-4499-AC14-25EB18E1D3DA" .EXAMPLE Get-SPClientListItem -Retrievals "Title" #> [CmdletBinding(DefaultParameterSetName = 'All')] param ( [Parameter(Mandatory = $false, ParameterSetName = 'All')] [Parameter(Mandatory = $false, ParameterSetName = 'Identity')] [Parameter(Mandatory = $false, ParameterSetName = 'IdentityGuid')] [Microsoft.SharePoint.Client.ClientContext] $ClientContext = $SPClient.ClientContext, [Parameter(Mandatory = $true, Position = 0, ValueFromPipeline = $true)] [Microsoft.SharePoint.Client.List] $ParentList, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [string] $FolderUrl, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [ValidateSet('FilesOnly', 'Recursive', 'RecursiveAll')] [string] $Scope, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [string[]] $ViewFields, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [string] $Query, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [int] $RowLimit, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [Microsoft.SharePoint.Client.ListItemCollectionPosition] $Position, [Parameter(Mandatory = $true, ParameterSetName = 'Identity')] [Alias('Id')] [int] $Identity, [Parameter(Mandatory = $true, ParameterSetName = 'IdentityGuid')] [Alias('UniqueId')] [guid] $IdentityGuid, [Parameter(Mandatory = $false)] [string] $Retrievals ) process { if ($ClientContext -eq $null) { throw "Cannot bind argument to parameter 'ClientContext' because it is null." } if ($PSCmdlet.ParameterSetName -eq 'All') { $Caml = New-object Microsoft.SharePoint.Client.CamlQuery if ($PSBoundParameters.ContainsKey('FolderUrl')) { $Caml.FolderServerRelativeUrl = $FolderUrl } $XmlDocument = New-Object System.Xml.XmlDocument $ViewElement = $XmlDocument.AppendChild($XmlDocument.CreateElement('View')) if ($PSBoundParameters.ContainsKey('Scope')) { $ViewElement.SetAttribute('Scope', $Scope) } if ($PSBoundParameters.ContainsKey('ViewFields')) { $ViewFieldsElement = $ViewElement.AppendChild($XmlDocument.CreateElement('ViewFields')) foreach ($ViewField in $ViewFields) { $FieldRefElement = $ViewFieldsElement.AppendChild($XmlDocument.CreateElement('FieldRef')) $FieldRefElement.SetAttribute('Name', $ViewField) } } if ($PSBoundParameters.ContainsKey('Query')) { $QueryElement = $ViewElement.AppendChild($XmlDocument.CreateElement('Query')) $QueryElement.InnerXml = $Query if ($QueryElement.FirstChild.Name -eq 'Query') { $QueryElement = $QueryElement.FirstChild } } if ($PSBoundParameters.ContainsKey('RowLimit')) { $RowLimitElement = $ViewElement.AppendChild($XmlDocument.CreateElement('RowLimit')) $RowLimitElement.InnerText = $RowLimit } if ($PSBoundParameters.ContainsKey('Position')) { $Caml.ListItemCollectionPosition = $Position } $Caml.ViewXml = $XmlDocument.InnerXml $ClientObjectCollection = $ParentList.GetItems($Caml) Invoke-SPClientLoadQuery ` -ClientContext $ClientContext ` -ClientObject $ClientObjectCollection ` -Retrievals $Retrievals Write-Output @(, $ClientObjectCollection) } if ($PSCmdlet.ParameterSetName -eq 'Identity') { $PathMethod = New-Object Microsoft.SharePoint.Client.ObjectPathMethod( ` $ClientContext, ` $ParentList.Path, ` 'GetItemById', ` [object[]]$Identity) $ClientObject = New-Object Microsoft.SharePoint.Client.ListItem($ClientContext, $PathMethod) Invoke-SPClientLoadQuery ` -ClientContext $ClientContext ` -ClientObject $ClientObject ` -Retrievals $Retrievals Write-Output $ClientObject trap { throw 'The specified list item could not be found.' } } if ($PSCmdlet.ParameterSetName -eq 'IdentityGuid') { $Caml = New-object Microsoft.SharePoint.Client.CamlQuery $Caml.ViewXml = ` '<View Scope="RecursiveAll">' + ` '<RowLimit>1</RowLimit>' + ` '<Query>' + ` '<Where>' + ` '<Eq>' + ` '<FieldRef Name="UniqueId"/>' + ` '<Value Type="Guid">' + $IdentityGuid + '</Value>' + ` '</Eq>' + ` '</Where>' + ` '</Query>' + ` '</View>' $ClientObjectCollection = $ParentList.GetItems($Caml) Invoke-SPClientLoadQuery ` -ClientContext $ClientContext ` -ClientObject $ClientObjectCollection ` -Retrievals $Retrievals if ($ClientObjectCollection.Count -eq 0) { throw 'The specified list item could not be found.' } Write-Output $ClientObjectCollection[0] } } } |
