Un esempio in PowerShell per SharePoint 2010 di come fare una query ricorsiva su più siti per elencare il contenuto delle liste utilizzando l'oggetto SPSiteDataQuery
PowerShell
$web = Get-SPWeb http://sharepoint2007/sito1
$query = New-Object Microsoft.Sharepoint.SPSiteDataQuery
//$query.Lists = "<Lists ServerTemplate='20101'/>";
$query.ViewFields = "<FieldRef Name='ID' /><FieldRef Name='Title' /><FieldRef Name='FileRef' /><FieldRef Name='EncodedAbsUrl' />";
$query.Webs = "<Webs Scope='Recursive' />";
$query.RowLimit = 1000
$web.GetSiteData($query) | Format-List
che da un risultato simile a questo
ListId        : 1500A7AE-D611-44C7-B89D-1934F6F034B4
WebId         : 4E5E5E32-9CED-4FB7-B96B-9DEFA28370AF
