The definition

Answer 1

I have automated this task.

create a form with a textbox named "TextBoxFile" and a button. In the code of the click button:

    Dim xmlDoc As New XmlDocument()
    xmlDoc.Load(TextBoxFile.Text)
    Dim root = xmlDoc.DocumentElement 

    For Each elel As XmlNode In root.ChildNodes
        Debug.WriteLine(elel.Name & " " & elel.NodeType)
    Next

    If root.Attributes()("xmlns").Value <> "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" Then
        root.Attributes()("xmlns").Value = "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition"
    End If

    Dim nsmgr = New XmlNamespaceManager(xmlDoc.NameTable)
    nsmgr.AddNamespace("bk", "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition")

    Dim autoRefreshElements = root.GetElementsByTagName("AutoRefresh")
    While autoRefreshElements.Count > 0
        root.RemoveChild(autoRefreshElements(0))
    End While

    Dim ReportParametersLayout = root.GetElementsByTagName("ReportParametersLayout")
    While ReportParametersLayout.Count > 0
        root.RemoveChild(ReportParametersLayout(0))
    End While

    Dim ReportSections = root.GetElementsByTagName("ReportSections")

    If ReportSections.Count > 0 Then
        ' Move content of ReportSections just below the block.
        Dim ReportSection = ReportSections(0).ChildNodes()

        ' First, copy the elements after
        Dim precedent = ReportSections(0)
        For Each child As XmlNode In ReportSection(0).ChildNodes
            Dim clone = child.Clone
            root.InsertAfter(clone, precedent)
            precedent = clone
        Next

        ' After deleting the existing block
        While ReportSections.Count > 0
            root.RemoveChild(ReportSections(0))
        End While
    End If

    xmlDoc.Save(TextBoxFile.Text) 

    MsgBox("Ok")
