This is a data source written to import questionnaire data exported from the Onyx questionnaire tool.

The tool exports a set of questionnaires into a series of sub-directories, each directory containing the results for all patients for one questionnaire. Each questionnaire folder contains a file called Entities.xml that maps patients to numbered XML files within the same directory (for example 00000001.xml).

Mapping Source

The source attribute list for mappings should contain two items. The first is the name of the questionnaire folder, the second is the name of the variable element within the patient's numbered XML file.
