How to Translate XML Data to Native Data

This section describes how to translate an incoming XML message to native data format (such as a comma delimited string). This example uses the schema file created in How to Translate Native Data to XML Data as the outbound XML format to translate to native XSD format.

To translate XML format to native data:

  1. Create a synchronous BPEL process.
  2. In the Input field of the Create BPEL Process dialog, accept the default input XSD schema or click the Search icon to select a different XSD. For this example, the schema created with the Native Format Builder in How to Translate Native Data to XML Data is selected. Figure 6-17 provides details.

  3. Right-click the BPEL process in the SOA Composite Editor, and select Edit.

    Oracle BPEL Designer is displayed.

  4. Expand the Oracle Extensions section of the Components window and drag a Translate activity into the BPEL process.
  5. Right-click the translate activity, and select Edit.

    The Translate dialog is displayed for editing.

  6. Select XML to Native to translate outbound XML data into native XSD format.
  7. To the right of the Input field, click the Browse (first) icon.
  8. Select the input variable. Figure 6-18 provides details.

  9. To the right of the NXSD Schema field, select the Search (first) icon to invoke the Type Chooser dialog.
  10. Select the schema file, and click OK. This example uses the same schema file as How to Translate Native Data to XML Data. Figure 6-19 provides details.

  11. From the Output Type list, select STRING.

    If you instead select ATTACHMENT, the dialog is refreshed to display the Location field for specifying the directory location for the attachment. Selecting ATTACHMENT is useful for scenarios in which XML data is very large.

  12. To the right of the Output field, click the Search (first) icon or click the Create Variable icon to automatically create a new output variable of type string.
  13. Select the output variable, and click OK. Figure 6-20 provides details.
