Remarks

Within a Switch statement, the Case element is often used in conjunction with the Default element. If the criteria set by the Case value proves false, then the default value is implemented.

Example

The following example checks the value of a UserID field and returns "User Zero" if the value is 0 (zero). Otherwise, it sets a default value: "Not User Zero".

<Switch>
  <Expr><UserID/></Expr>
  <Case Value="0">User Zero</Case>
  <Default>Not User Zero</Default>
</Switch>
