Adding an XQuery Node

Now that we understand how the XQuery code in createFullOrder.xquery uses a FLWOR expression to join data from our data sources, we can add it to our XML pipeline.

To add an XQuery node to an XML pipeline:

Stylus Studio creates an XQuery node and displays it in the XML pipeline diagram.

The XQuery node now has two additional input ports, one named allBooks, and the other named ediOrder.

Changes to Source Documents

XML pipelines reference external documents, like the createFullOrder.xquery document we just added. They do not create copies of these documents. Therefore, when changes to a source document are saved, the XML pipeline picks up these changes the next time it is executed.
