Usage

This property must be set to specify the type of metadata
generated before you call the SaveAs method with XML! as the SaveAsType
to save data as an XML document, or use the .Data.XML expression to save
data as an XML string. The metadata is saved into the exported XML
itself or into an associated file, depending on the value of the
Export.XML.SaveMetaData property.

The Export.XML.MetaDataType property is an enumerated datatype
that can hold the following values:

If the data item for a column is null or an empty string, an empty
element is created when you export XML. If you select XMLSchema!, child
elements with null data items are created with the content
“xsi:nil=’true'”.

In the painter

In the Data Export tab in the Properties view for the DataWindow
object, select XML from the Format to Configure list and select a value
from the Meta Data Type list.

Examples

This statement specifies that no metadata will be generated when
the DataWindow is exported to XML:

These statements export the contents of dw1 to the file
c:myxml.xml using the XML export template called t_schema, and generate
an external XML schema file at c:myxml.xsd:
