XML-NODE-TYPE attribute

The XML node type of the buffer-field object, which lets you specify how a buffer field is represented in XML and XML Schema. Valid XML node types are "ATTRIBUTE", "ELEMENT", "HIDDEN", and "TEXT".

Data type: CHARACTER

Access: Readable/Writeable

Applies to: Buffer-field object handle

Table 110 lists the valid XML node types.

Table 110: XML node types 

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".

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.
