Using XML Objects in XPRESS

You can use XML objects within XPRESS anywhere an expression is allowed. In the example below, a map is passed as an argument to an invoked method.

<invoke name=’printTheMap’>
    <ref>mapPrinter</ref>
       <Map>
       </Map>
</invoke>

In releases prior to 2.0, XPRESS required that all XML Objects be wrapped in an <o> element. While this is no longer required, you may still encounter its use in older files containing XPRESS.
