dpkq is a data picker based on the Epeios framework. It randomly picks a record from a table stored in an XML file, putting this unique record in another XML file, associating it with an XSL file, so it can be displayed with an HTML layout in a Web browser.

<project> is the project file name, which contains, under other, the filename containing the data, and the XSL filename.

For a typical use of dpkq, you don't give an <id>, but, if you want to display a specific record, give its index as <id>, and to display all records; give 0 as <id>.

When dpkq picks randomly a record, it never picks an already picked record until all other records were picked at least once. The file used to keep the trace of already picked records are stored in a file defined in the project file.

When all records were picked, recently picked records are not picked again, unless you begin a new session, and all the record were picked in the previous session. All calls belong to the same session as long then the previous call occurs in a delay lesser the defined in the project file.
