XML - Exporting Data Automatically

The following example, for Logi Info only, shows how to create a Process task that exports data automatically:

  1. As shown above, in your Process definition, add a Task element and beneath it a Procedure.Export XML element.
  2. In the element's Filename attribute, specify the output path and filename, on the web server, for the exported report. The filename should include the ".XML" file extension. The example shown above uses an @Function token to provide the path to the Logi application's application folder on the web server.

  1. Next, add the required Target.XML element, as shown above.
  2. In the element's Report Definition File attribute, specify the report that contains the data to be exported. Do not select the CurrentReport option in the list of suggestions as it will notwork.
  3. Your task will need to be completed, of course, with a Response element to run properly.

What happens when your task runs? The specified report data will be exported to a temporary file in your project folder's rdDownload folder on the web server; then the temp file will be copied to the output file you specified. If you try to run this task more than once, you'll receive an error. This is due to the fact that Procedure.Export XML will not overwrite an existing file. Adding a Procedure.Delete File element at the beginning of the task will solve this.

An example of a complete task is shown above. Note the use of the @Function again in the Procedure.Delete File element's Filename attribute. Logi products also include an XSL Transform element, which allows you to apply transformations to change the XML output format before the data is exported.
