Once you have an XML-enabled record, you'll need to access it from the Procedure Division of your program. You can use existing COBOL verbs to do this and the XML-enhanced syntax for these verbs. See the topic XML Syntax Extensions for more information.
The following is a sample program with a Procedure Division that writes the contents of the widgets.xml file:
$set p(prexml) endp select xml-stream assign "widgets.xml" organization is xml document-type is "widgets.xsd" file status is file-status-spec. xd xml-stream. copy "widgets.cpy". data division. working-storage section. 01 file-status-spec PIC S9(9). procedure division. open output xml-stream write widgets display file-status-spec close xml-stream stop run.
