The MAKECHARACTERDATA function is used to convert a generic DOM node into a character data node handle, which can then be used with GETDATA to retrieve the character content within the node.
Applicability
This content applies only to OceanBase Database Enterprise Edition. OceanBase Database Community Edition provides only the MySQL-compatible mode.
Note
For V4.4.2, this subprogram is available starting with OceanBase Database V4.4.2 BP3.
Syntax
DBMS_XMLDOM.makeCharacterData (
node IN DBMS_XMLDOM.DOMNODE);
Parameters
Parameters |
Explanation |
|---|---|
| node | To be convertedDBMS_XMLDOM.DOMNODEHandle. |
Return value
Handle of the DBMS_XMLDOM.DOMCHARACTERDATA character data node.
Usage instructions
The conversion is meaningful only if the node itself is a character data node (such as a text node). After conversion, you can use GETDATA to read the content.
Examples
DECLARE
doc DBMS_XMLDOM.DOMDOCUMENT;
text DBMS_XMLDOM.DOMTEXT;
node DBMS_XMLDOM.DOMNODE;
character_data DBMS_XMLDOM.DOMCHARACTERDATA;
BEGIN
doc := DBMS_XMLDOM.newDOMDocument;
text := DBMS_XMLDOM.createTextNode(doc, 'hello');
node := DBMS_XMLDOM.makeNode(text);
character_data := DBMS_XMLDOM.makeCharacterData(node);
DBMS_XMLDOM.freeDocument(doc);
END;
