The Document Object Model (DOM) is an application programming interface (API) for HTML and XML documents. It defines the logical structure of documents, and the manner in which they are accessed and manipulated. In the DOM specification, the term "document" is used in the broad sense. XML is being increasingly used to represent many different kinds of information that may be stored in diverse systems. This information has been traditionally be seen as "data"; nevertheless, XML presents this data as documents, and the DBMS_XMLDOM
package allows you access to both schema-based and non schema-based documents.
Note:
Before database startup, the read-from and write-to directories in the init.ORA
file must be specified; for example: UTL_FILE_DIR=/mypath/insidemypath
.
Read-from and write-to files must be on the server file system.
With DOM, anything found in an HTML or XML document can be accessed, changed, deleted, or added using the Document Object Model, with a few exceptions. In particular, the DOM interfaces for the XML internal and external subsets have not yet been specified.
One important objective of the W3C DOM specification is to provide a standard programming interface that can be used in a wide variety of environments, programming languages, and applications. Because the DOM standard is object-oriented while PL/SQL is essentially a procedural language, some changes had to be made:
Various DOM interfaces such as Node
, Element
, and others have equivalent PL/SQL types DOMNode
, DOMElement
, respectively.
Various DOMException
codes such as WRONG_DOCUMENT_ERR
, HIERARCHY_REQUEST_ERR
, and others, have similarly named PL/SQL exceptions.
Various DOM Node type codes such as ELEMENT_NODE
, ATTRIBUTE_NODE
, and others, have similarly named PL/SQL constants.
Subprograms defined on a DOM type become functions or procedures that accept it as a parameter. For example, to perform APPENDCHILD Function on a DOMNode
n
, the APPENDCHILD FunctionPL/SQL function is provided.
To perform setAttribute
on a DOMElement elem
SETATTRIBUTE Procedures, use PL/SQL procedure .
DOM defines an inheritance hierarchy. For example, Document
, Element
, and Attr
are defined to be subtypes of Node
(see Figure 167-1). Thus, a method defined in the Node
interface should be available in these as well. Since such inheritance is not supported in PL/SQL, it is implemented through direct invocation of the MAKENODE
function. Calling MAKENODE
on various DOM types converts these types into a DOMNode
. The appropriate functions or procedures that accept DOMNode
s can then be called to operate on these types. If, subsequently, type specific functionality is desired, the DOMNode
can be converted back into the original type by the make
XXX
functions, where DOM
XXX
is the desired DOM type.
Figure 167-1 Inheritance Diagram for DOM Types
The implementation of this interface follows the REC-DOM-Level-1-19981001.

This function adopts a node from another document, and returns this new node.

DBMS_XMLDOM.ADOPTNODE( doc IN DOMDocument, importedNode IN DOMNode) RETURN DOMNODE;
Parameters
Table 167-22 ADOPTNODE Function Parameters
Parameter | Description |
---|---|
|
Document that is adopting the node |
|
Node to adopt |
Usage Notes
Note that the ADOPTNODE Function removes the node from the source document while the IMPORTNODE Function clones the node in the source document.
This function adds the node newchild
to the end of the list of children of this node, and returns the newly added node. If the newchild
is already in the tree, it is first removed.

DBMS_XMLDOM.APPENDCHILD( n IN DOMNode, newchild IN DOMNode) RETURN DOMNODE;
Parameters
Table 167-23 APPENDCHILD Function Parameters
Parameter | Description |
---|---|
|
|
|
The child to be appended to the list of children of node |
This procedure appends the string to the end of the character data of the node. Upon success, data provides access to the concatenation of data and the specified string argument.

Parameters

Parameter | Description |
---|---|

This function returns a duplicate of this node, and serves as a generic copy constructor for nodes. The duplicate node has no parent, its parent node is NULL
.

DOMNode SubprogramsSyntax
DBMS_XMLDOM.CLONENODE( n IN DOMNODE, deep IN BOOLEAN) RETURN DOMNODE;
Parameters
Table 167-25 CLONENODE Function Parameters
Parameter | Description |
---|---|
|
|
|
Determines if children are to be cloned |
Usage Notes
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node.
Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute (specified is TRUE
).
Cloning any other type of node simply returns a copy of this node.

This procedure is overloaded. The specific forms of functionality are described along with the syntax declarations.
Syntax
Sets the character data of the node that implements this interface (See Also: DOMCharacterData Subprograms):

Given a DOM document, this procedure creates a new DTD with the specified name, system id and public id and sets it in the document. This DTD can later be retrieved using the GETDOCTYPE Function.
Syntax
DBMS_XMLDOM.SETDOCTYPE( doc IN DOMDocument, name IN VARCHAR2, sysid IN VARCHAR2, pubid IN VARCHAR2);
Parameters
Table 167-121 SETDOCTYPE Procedure Parameters
Parameter | Description |
---|---|
|

This function adds a node using its NodeName
attribute. If a node with that name is already present in this map, it is replaced by the new one. The old node is returned on replacement; if no replacement is made, NULL
is returned.
As the NodeName
attribute is used to derive the name under which the node must be stored, multiple nodes of certain types, those that have a "special" string value, cannot be stored because the names would clash. This is seen as preferable to allowing nodes to be aliased.

This function returns an instance of the PL/SQL XMLBINARYOUTPUTSTREAM
into which the caller can write the node value. The data type of the node must be RAW
or BLOB
– if not, an exception is raised.
DBMS_XMLDOM.SETNODEVALUEASBINARYSTREAM ( n IN DOMNODE) RETURN SYS.UTL_BINARYOUTPUTSTREAM;
Using this procedure, the application passes in an implementation of sys
.utl_BinaryInputStream
from which XDB reads data to populate the node. The data type of the node must be RAW
or BLOB – if not an exception is raised.
DBMS_XMLDOM.SETNODEVALUEASBINARYSTREAM ( n in DOMNODE, value in SYS.UTL_BINARYINPUTSTREAM);

This function returns an instance of the PL/SQL XMLCHARACTEROUTPUTSTREAM
type into which the caller can write the node value. The data type of the node can be any valid XDB data type. If the type is not character or CLOB
, the character data written to the stream is converted to the node data type. If the data type of the node is character or CLOB
, then the character data written to the stream is converted from PL/SQL session character set to the character set of the node.
DBMS_XMLDOM.SETNODEVALUEASCHARACTERSTREAM ( n IN DOMNODE) RETURN SYS.UTL_CHARACTEROUTPUTSTREAM;
Using this procedure, the application passes in an implementation of SYS
.UTL_CHARACTERINPUTSTREAM
from which XDB reads to populate the node. The data type of the node may be any valid type supported by XDB. If a non-character data type, the character data read from the stream is converted to the data type of the node. If the data type of the node is either character or CLOB
, then no conversion occurs and the character set of the node becomes the character set of the PL/SQL session.
