Overview

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.

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 elemSETATTRIBUTE 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 125-1). 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 DOMNodes 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 makeXXX functions, where DOMXXX is the desired DOM type.

The implementation of this interface follows the REC-DOM-Level-1-19981001.

Summary of DBMS_XMLDOM Subprograms

---

ADOPTNODE Function

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

Syntax

DBMS_XMLDOM.ADOPTNODE(
   doc            IN   DOMDocument,
   importedNode   IN   DOMNode)
 RETURN DOMNODE;

Parameters

---

APPENDCHILD Function

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.

Syntax

DBMS_XMLDOM.APPENDCHILD(
   n          IN    DOMNode,
   newchild   IN    DOMNode)
 RETURN DOMNODE;

Parameters

---

APPENDDATA Procedure

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.

Syntax

DBMS_XMLDOM.APPENDDATA(
   cd      IN    DOMCHARACTERDATA, 
   arg     IN    VARCHAR2);

Parameters

---

CLONENODE Function

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.

 RETURN DOMNODE;

Parameters

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.

---

SETNAMEDITEM Function

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.

Syntax

Adds a node using its NodeName attribute:
