Reads out the repeating element automatically. A repeating element already set by a user will not be considered. The repeating element will be displayed corresponding to the hierarchy of the xml elements, e.g., <element>/<repeating element>. Depending on the repeating element, the requested columns will be displayed in the Columns box.

XML element that is repeated for each row (XPath to repeat element);

You can edit the repeating element manually.

Specify a valid XPath expression, e.g.,

Advanced parsing options

EMML parsing: EMML compatibility mode. If selected, the XML Data source determines data types analogous to EMML, and parse data the way EMML does.

Default is unselected.

Columns: Detect
