Steps

To display a list of orphaned pages (pages with no parent) using a Velocity script:

1. Make sure your administrator gives you programming rights.
2. Edit the page using the Wiki editor.
3. Add the following code to the page content:

   {{velocity}}
   #set($query = "where doc.parent is null or doc.parent='' order by doc.name asc")
   
   #foreach($item in $services.query.xwql($query).execute())
     #set($orphanedDoc = $xwiki.getDocument($item))
     * [[$orphanedDoc.displayTitle>>$orphanedDoc]] (located in //$orphanedDoc.space//, contains $orphanedDoc.attachmentList.size() attachments)
   #end
   {{/velocity}}

4. Save the page.
5. Notice how the page now renders a bulleted list of orphaned documents, each showing its space and attachment count:
