XPaths on output link

Each output column that has an XPath expression is a candidate for receiving XML. The source of the XML for an output column are those input columns whose XPath expressions start with and contain the same nodes.

To make the entire XML available to an output column, use one forward slash as the XPath expression. The forward slash identifies the root node.

The following table demonstrates the relationship between XPath expressions on the input and output links. Two output columns use XPath expressions that form the first part of one of more XPath expressions used by input columns. For example, the output column that uses the XPath expression /orders receives XML generated using the XPath expressions /orders/cust and /orders/items. The column that uses the forward slash receives all the XML.
