Today my colleague Johannes Milling wrote an awesome post: Export SharePoint List Data To XML Directly from the GUI He uses the old and forgotten RPC-based web service owssvr.dll (that has existed since SharePoint 2003). This url pattern is used to get the xml-formatted list data for a specific ListView: [source] http://<site_url>/_vti_bin/owssvr.dll?Cmd=Display&List=&View=&Query=*&XMLDATA=TRUE [/source] To automate this I have written a PowerShell function. All the details are in the comments: [source language=“PowerShell”] function Export-OIPSPListDataAsXml { <# .Synopsis Exports list items as xml .DESCRIPTION This function uses a built-in hidden service owssvr.dll in SharePoint .PARAMETER Web SPWeb or a url for the SPWeb object where the list resides .PARAMETER ListName List Name (List Title) .PARAMETER ViewName Name of the List View to export the data .EXAMPLE Export-OIPSPListView -Web http://myawesomesite -ListName “Teddy Bears” -ViewName “All Items” .EXAMPLE Export-OIPSPListView -Web $webInstance -ListName “Top Links” -ViewName “All Items” .Notes Name: Export-OIPSPListDataAsXml Author: Anatoly Mironov Last Edit: 2014-09-11 Keywords: SPList, SPWeb, SPListView, Xml .Link http://chuvash.eu #> [CmdLetBinding()] param( [Parameter(Mandatory=$true)] [Microsoft.SharePoint.PowerShell.SPWebPipeBind]$Web, [Parameter(Mandatory=$true)] [string]$ListName, [Parameter(Mandatory=$true)] [string]$ViewName) $spWeb = $Web.Read() $list = $spWeb.Lists[$ListName] if (!$list) { throw “List $ListName on web $($spWeb.Url) could not be found” } $view = $list.Views[$ViewName] if (!$view) { throw “View $ViewName on web $ListName could not be found” } $url = “{0}/_vti_bin/owssvr.dll?Cmd=Display&List={1}&View={2}&Query=*&XMLDATA=TRUE” ` -f $spWeb.Url, $list.ID, $view.ID $wc = New-Object Net.WebClient $wc.UseDefaultCredentials = $true $wc.DownloadString($url) } [/source]
