Remarks

Exporting the query content

To export the query content, you must initialize the query (<Fichier HFSQL>.ExécuteRequête) before using <Source>.ExportXML.

Exporting a single record

To export a single record to an XML string, use <Source>.RecordToXML.

Array items

If one of the exported items is an array item, each element of the array item is exported in a new level:
<FILE>
<ITEM1>data of item 1</ITEM1>
<ITEM2>data of item 2</ITEM2>
<ARRITEM>
<ARRITEM_1>data of element 1</ARRITEM_1>
<ARRITEM_2>data of element 2</ARRITEM_2>
<ARRITEM_3>data of element 3</ARRITEM_3>
</ARRITEM>
...
</FILE>

Reminder: Composite key, binary memo or binary items are ignored.
