XML-NODE-TYPE attribute

The XML node type of the buffer-field or ProDataSet object, which lets you specify how the object is represented in XML and XML Schema.
Data type: CHARACTER
Access: Readable/Writeable
Applies to: Buffer-field object handle, ProDataSet object handle
The following table lists the valid XML node types for a buffer-field object.
Table 115. XML node types for buffer-field objects
When the XML node type is . . .
The buffer field is . . .
"ATTRIBUTE"
Represented as an attribute of the temp-table element in both the XML Schema and data.
"ELEMENT"
Represented as a child element of the temp-table element in both the XML Schema and data.
"HIDDEN"
Omitted from both the XML Schema and data.
"TEXT"
Represented as a text element in both the XML Schema and data.
Note: Each table can contain only one "TEXT" field. When a table contains a "TEXT" field, it cannot contain "ELEMENT" fields; it can contain only "ATTRIBUTE" fields. A table that contains a "TEXT" field cannot be part of a nested data-relation.
The XML node type of a buffer field that represents an array must be either "ELEMENT" or "HIDDEN".
The following table lists the valid XML node types for a ProDataSet object.
Table 116. XML node typesfor ProDataSet objects
When the XML node type is . . .
The ProDataSet name is . . .
"ELEMENT"
Represented as the root element in both the XML Schema and data.
"HIDDEN"
Omitted from both the XML Schema and data.
This attribute's purpose overlaps with the SERIALIZE-HIDDEN attribute. Because of this overlap, the attributes interact as follows:
*The WRITE-XML( ) method always uses the XML-NODE-TYPE attribute value. If you set a value for the XML-NODE-TYPE attribute, it keeps that value regardless of how you set the SERIALIZE-HIDDEN attribute.
*If you do not set the XML-NODE-TYPE attribute and set the SERIALIZE-HIDDEN attribute to TRUE, the AVM sets XML-NODE-TYPE to "HIDDEN".
*If you do not set the XML-NODE-TYPE attribute and set the SERIALIZE-HIDDEN attribute to FALSE, the AVM sets XML-NODE-TYPE to "ELEMENT".
*If you do not set either attribute, the AVM sets XML-NODE-TYPE to "ELEMENT" and sets SERIALIZE-HIDDEN to FALSE.
