Integrating remote XML data

The Digital Data Connector (DDC) for HCL Portal framework provides a generic XML DDC plug-in that is ready to use for integrating external XML data of your choice. You can use this plug-in to render external XML data on your portal pages without having to write custom Java code.

The generic XML DDC plug-in supports the concept of list-rendering profiles. It therefore makes it possible to integrate XML data. The XML data can be served in arbitrary XML document formats. A list-rendering profile describes the transformation between a specific XML document format and the generic bean list data structure that the DDC framework supports. In addition, the list-rendering profile enumerates all attribute names of the items in the resulting bean list that you can add to the result markup. This way, the HCL Web Content Manager Insert Tag user interface can present a dedicated selection box. That selection box contains all supported attributes for a specific list-rendering profile when you author DDC list appearance components.

  • The generic XML Digital Data Connector plug-in
    You can use the Digital Data Connector (DDC) for HCL Portal plug-in directly to integrate remote XML data without coding. It makes it possible to integrate XML data that is served in arbitrary XML document formats by supporting the concept of list-rendering profiles.
  • Syntax for XPath based list-rendering profiles
    An XPath based list-rendering profile contains a set of name-value pairs called entries. This set of entries defines the set of available list properties and item attributes that are available for transforming external data into bean lists.
  • Syntax for custom list-rendering profiles
    Custom Digital Data Connector (DDC) for HCL Portal plug-ins that do not delegate the initial bean list computation to the generic XML DDC plug-in can use a custom list-rendering profile. This case typically occurs when you integrate non-XML data.
  • The Atom list-rendering profile
    Digital Data Connector (DDC) for HCL Portal provides a list-rendering profile that is ready to use for access to feeds that comply with the Atom syndication format standard.
