Displaying XML Content 
The portal provides several ways of working with XML content and performing transformations:
XML iViews
The portal comes with an XML iView template that enables administrators to specify an XML source and one of the built-in transformers. The iView displays the transformed content.
This method is for administrators who are working with an HTTP-based XML source, whose XML content can use one of the built-in transformers.
For more information, see Creating XML iViews.
Creating Transformers
You can build additional transformers for the XML iView. The custom transformers are displayed to administrators in the XML iView wizard.
For more information, see Providing Transformers.
Using the Transformation Service
You can create a portal component that performs its own transformations, with the help of the transformation service.
For more information, see Transformation Service.
