What is the XML activity node?

The XML Activity Node allows XML to be built or parsed within a process. XML is read or constructed as JavaScript objects so that elements or their contents can be accessed within the process, especially using the Assign and Branch nodes. The XML node has a built-in wizard that aids in the construction of XML based on an XML Schema (XSD). The node also has an output wizard that informs the Designer what XML elements are expected as output, based on the schema, so that these elements may more easily be referenced in other nodes.
