GETNODETYPE

The GETNODETYPE function is used to obtain the type number of a DOM node, which helps distinguish between different categories of DOM nodes such as element nodes, attribute nodes, text nodes, and document nodes.

Syntax

DBMS_XMLDOM.getNodeType (
   n IN DBMS_XMLDOM.DOMNODE);

Parameters

Return value

Node type number, of the NUMBER data type. Common values can be compared with the following DBMS_XMLDOM constants:

Usage instructions

The return value semantics are consistent with Oracle DOM node type constants, allowing direct comparison with constants such as DBMS_XMLDOM.ELEMENT_NODE and DBMS_XMLDOM.TEXT_NODE, for branching processing of different node categories.

Examples

DECLARE
  n         DBMS_XMLDOM.DOMNODE;
  node_type NUMBER;
BEGIN
  node_type := DBMS_XMLDOM.getNodeType(n);
  IF node_type = DBMS_XMLDOM.ELEMENT_NODE THEN
    NULL; -- Element node processing
  ELSIF node_type = DBMS_XMLDOM.TEXT_NODE THEN
    NULL; -- Text node processing
  END IF;
END;
