Remarks

The Method element is required for the Batch element, which is embedded within HTTP protocol and allows the client application to post more than one command at a time to the server.

In operations where the SetVar element is used within the Method element to post commands, the Cmd attribute can contain methods in the SharePoint Foundation RPC Protocol protocol.

When used with the UpdateListItems method of the Lists Web service, each Method element contains Field elements that specify the column values for each item being updated.

Example

The following example uses the Method element to post the remote procedure call (RPC) ExportList command and return the schema of a specified list.

<Batch OnError="Return">
  <Method ID="0,ExportList">
    <SetList Scope="Request">EF2F5A21-0FD0-4654-84ED-
        112B4F5A48F8</SetList>
    <SetVar Name="Cmd">ExportList</SetVar>
  </Method>
</Batch>
