You can include PowerCenter XML sources and targets as tables in single-table constraints and table pairs.
You can include one or more XML groups in the XML hierarchy in a single-table constraint or table pair. By default, you can include one XML group in a single-table constraint or table pair.
To include multiple XML groups, create a join view based on the XML file. The join view converts the hierarchical XML data to a relational structure. You can specify which XML groups to include in the join view. You can use the join view as a table in a single-table constraint or table pair.
You can reuse the same join view for multiple XML files that have the same structure. For example, you create a join view based on an XML file and add the join view to a table pair. You create another table pair based on the same join view and override the XML connection properties. You change the XML connection to point to a different XML file in a different location.
