About Order Sequence Order Item Selector XQuery Expressions

This topic describes how to use the Orchestration Sequence editor Order Item Selector area XQuery tab to write an expression that specifies which node-set to use from the customer order as order items and has the following characteristics:

  • Context: The input document for the Order Item Selector XQuery is the customer order. For more information about typical customer order structures, see OSM Modeling Guide.

  • Prolog: You can declare the customer order namespace in the XQuery prolog.

  • Body: The XQuery body must specify the customer order node-sets that OSM then uses as order items.

The following example shows an order item selector XQuery where the <salesOrderLine> node-set is specified. OSM can now use the data in the <salesOrderLine> node-set in the incoming customer order in the order items. There can only be one node-set selected per sequence. 

declare namespace im="http://xmlns.oracle.com/InputMessage";
.//im:salesOrderLine
