2 Package Dom APIs for C++

Interfaces in this package represent DOM level 2 Core interfaces according to http://www.w3.org/TR/DOM-Level-2-Core/.

This chapter contains the following sections:

Using Dom

DOM interfaces are represented as generic references to different implementations of the DOM specifications. They are parameterized by Node, which supports various specializations and instantiations. Of them, the most important is xmlnode that corresponds to the current C implementation.

These generic references do not have a NULL-like value. Any implementation should never create a stateless reference. If there is need to signal that something has no state, an exception should be thrown.

Many methods might throw the SYNTAX_ERR exception, if the DOM tree is incorrectly formed, or UNDEFINED_ERR, in the case of wrong parameters or unexpected NULL pointers. If these are the only errors that a particular method might throw, it is not reflected in the method signature.

Actual DOM trees do not dependent on the context (TCtx). However, manipulations on DOM trees in the current, xmlctx based implementation require access to the current context (TCtx). This is accomplished by passing the context pointer to the constructor of DOMImplRef. In multithreaded environment DOMImplRef is always created in the thread context and, so, has the pointer to the right context.

DOMImplRef providea a way to create DOM trees. DomImplRef is a reference to the actual DOMImplementation object that is created when a regular, non-copy constructor of DomImplRef is invoked. This works well in multithreaded environment where DOM trees need to be shared, and each thread has a separate TCtx associated with it. This works equally well in a single threaded environment.

DOMString is only one of encodings supported by Oracle implementations. The support of other encodings is Oracle's extension. The oratext* data type is used for all encodings.

offset
character offset where insertion starts
data
data to insert

void setData( 
   oratext* data) 
throw (DOMException);
Parameter Description
data
data


substringData()

Returns a range of character data from a CharacterData node (type Text, Comment or CDATA). Since the data is in the data encoding, offset and count are in characters, not bytes. The beginning of the string is offset 0. If the sum of offset and count exceeds the length, then all characters to the end of the data are returned. The substring is permanently allocated in the context managed memory and should be explicitly deallocated by freeString

Syntax

oratext* substringData( 
   ub4 offset, 
   ub4 count) 
throw (DOMException);
Parameter Description
offset
offset
count
number of characters to extract

Syntax

Node* createElement(
   oratext* tagname)
throw (DOMException);
Parameter Description
tagname
tag name

Returns

(Node*) New element node


createElementNS()

Creates an element with the given namespace URI and qualified name. The new node is an orphan with no parent. The URI and qualified name are not copied, their pointers are just stored. The user is responsible for persistence and freeing of that data.

Note that element names are case sensitive, and the qualified name is required though the URI may be NULL. The qualified name will be split into prefix and local parts. The tagName will be the full qualified name.

Returns the DTD node associated with this document. After this call, a DocumentTypeRef object needs to be created with an appropriate constructor in order to call its member functions. The DTD tree cannot be edited.

Syntax

Node* getDoctype() const;

Returns

(Node*) DTD node


getDocumentElement()

Returns the root element (node) of the DOM tree. Each document has only one uppermost Element node, called the root element. If there is no root element, NULL is returned. This can happen when the document tree is being constructed.

Syntax

Node* getDocumentElement() const;

Returns

(Node*) Root element


getElementById()

Returns the element node which has the given ID. Throws NOT_FOUND_ERR if no element is found. The given ID should be in the data encoding or it might not match.

Note that attributes named "ID" are not automatically of type ID; ID attributes (which can have any name) must be declared as type ID in the DTD or XML schema associated with the document.

Syntax

Node* getElementById(
   oratext* elementId);
Parameter Description
elementId
element id

Returns

(Node*)Element node


getElementsByTagName()

Returns a list of all elements in the document with a given tag name, in document order (the order in which they would be encountered in a preorder traversal of the tree). The list should be freed by the user when it is no longer needed. The list is not live, it is a snapshot. That is, if a new node which matched the tag name were added to the DOM after the list was returned, the list would not automatically be updated to include the node.

The special name "*" matches all tag names; a NULL name matches nothing. Note that tag names are case sensitive, and should be in the data encoding or a mismatch might occur.

This function is not namespace aware; the full tag names are compared. If two qualified names with two different prefixes both of which map to the same URI are compared, the comparison will fail.

Syntax

NodeList< Node>* getElementsByTagName( 
   oratext* tagname) const;
Parameter Description
tagname
tag name

Returns

(NodeList< Node>*) List of nodes


getElementsByTagNameNS()

Returns a list of all elements in the document with a given namespace URI and local name, in document order (the order in which they would be encountered in a preorder traversal of the tree). The list should be freed by the user when it is no longer needed. The list is not live, it is a snapshot. That is, if a new node which matches the URI and local name were added to the DOM after the list was returned, the list would not automatically be updated to include the node.

The URI and local name should be in the data encoding. The special name "*" matches all local names; a NULL local name matches nothing. Namespace URIs must always match, however, no wildcard is allowed. Note that comparisons are case sensitive.

Syntax

NodeList< Node>* getElementsByTagNameNS(
   oratext* namespaceURI,
   oratext* localName);
Parameter Description
namespaceURI
namespace URI to match
localName
local name to match

Returns

(NodeList< Node>*) List of nodes


getImplementation()

Returns DOMImplementation object that was used to create this document. When the DOMImplementation object is destructed, all document trees associated with it are also destructed.

Syntax

DOMImplementation< Node>* getImplementation() const;

Returns

(DOMImplementation) DOMImplementation reference object


importNode()

Imports a node from one Document to another. The new node is an orphan and has no parent. The original node is not modified in any way or removed from its document; instead, a new node is created with copies of all the original node's qualified name, prefix, namespace URI, and local name.

The deep parameter controls whether the children of the node are recursively imported. If FALSE, only the node itself is imported, and it will have no children. If TRUE, all descendents of the node will be imported as well, and an entire new subtree created. Elements will have only their specified attributes imported; non-specified (default) attributes are omitted. New default attributes (for the destination document) are then added. Document and DocumentType nodes cannot be imported.

Syntax

Node* importNode( 
   NodeRef< Node>& importedNode,
   boolean deep) const
throw (DOMException);
Parameter Description
importedNode
node to import
deep
indicator for recursively importing the subtree

Returns

(Node*) New imported node

Class constructor.

Syntax Description
NodeRef(
   const NodeRef< Node>& nref,
   Node* nptr);
Used to create references to a given node when at least one reference to this node or another node is already available. The node deletion flag is not copied and is set to FALSE.
NodeRef(
   const NodeRef< Node>& nref);
Copy constructor. Used to create additional references to the node when at least one reference is already available. The node deletion flag is not copied and is set to FALSE.

Parameter Description
node_ref
reference to provide the context
nptr
referenced node

Returns

(NodeRef) Node reference object


appendChild()

Appends the node to the end of this node's list of children and returns the new node. If newChild is a DocumentFragment, all of its children are appended in original order; the DocumentFragment node itself is not. If newChild is already in the DOM tree, it is first removed from its current position.

cloneNode()

Creates and returns a duplicate of this node. The duplicate node has no parent. Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but it does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of the node. If deep is TRUE, all children of the node are recursively cloned, and the cloned node will have cloned children; a non-deep clone will have no children. If the cloned node is not inserted into another tree or fragment, it probably should be marked, through its reference, for deletion (by the user).

getAttributes()

Returns NamedNodeMap of attributes of this node, or NULL if it has no attributes. Only element nodes can have attribute nodes. For other node kinds, NULL is always returned. In the current implementation, the node map of child nodes is live; all changes in the original node are reflected immediately. Because of this, side effects can be present for some DOM tree manipulation styles, in particular, in multithreaded environments.

Syntax

NamedNodeMap< Node>* getAttributes() const;

Returns

(NamedNodeMap*) NamedNodeMap of attributes


getChildNodes()

Returns the list of child nodes, or NULL if this node has no children. Only Element, Document, DTD, and DocumentFragment nodes may have children; all other types will return NULL. In the current implementation, the list of child nodes is live; all changes in the original node are reflected immediately. Because of this, side effects can be present for some DOM tree manipulation styles, in particular, in multithreaded environments.

Syntax

NodeList< Node>* getChildNodes() const;

Returns

(NodeList*) the list of child nodes


getFirstChild()

Returns the first child node, or NULL, if this node has no children

Syntax

oratext* getLocalName() const;

Returns

(oratext*) local name of this node


getNamespaceURI()

Returns the namespace URI of this node (in the data encoding) as a NULL-terminated string. If the node's name is not qualified (does not contain a namespace prefix), it will have the default namespace in effect when the node was created (which may be NULL).

Returns

(oratext*) namespace URI of this node


getNextSibling()

Returns the next sibling node, or NULL, if this node has no next sibling

Syntax

(boolean) TRUE if no modifications are allowed


getNodeName()

Returns the (fully-qualified) name of the node (in the data encoding) as a NULL-terminated string, for example "bar\0" or "foo:bar\0". Some node kinds have fixed names: "#text", "#cdata-section", "#comment", "#document", "#document-fragment". The name of a node cannot changed once it is created.

Syntax

DOMNodeType getNodeType() const;

Returns

(DOMNodeType) of the node


getNodeValue()

Returns the "value" (associated character data) for a node as a NULL-terminated string. Character and general entities will have been replaced. Only Attr, CDATA, Comment, ProcessingInstruction and Text nodes have values, all other node types have NULL value.

Syntax

oratext* getNodeValue() const;

Returns

(oratext *) value of node


getOwnerDocument()

Returns the document node associated with this node. It is assumed that the document node type is derived from the node type. Each node may belong to only one document, or may not be associated with any document at all, such as immediately after it was created on user's request. The "owning" document [node] is returned, or the WRONG_DOCUMENT_ERR exception is thrown.

Syntax

Node* getOwnerDocument() const throw (DOMException);

Returns

(Node*) the owning document node


getParentNode()

Returns the parent node, or NULL, if this node has no parent

Syntax

Node* getParentNode() const;

Returns

(Node*) the parent node, or NULL

Returns the namespace prefix of this node (in the data encoding) (as a NULL-terminated string). If this node's name is not fully qualified (has no prefix), NULL is returned.

Syntax

oratext* getPrefix() const;

Returns

(oratext*) namespace prefix of this node


getPreviousSibling()

Returns the previous sibling node, or NULL, if this node has no previous siblings

Syntax

Node* getPreviousSibling() const;

Returns

(Node*) the previous sibling node, or NULL


hasAttributes()

Returns TRUE if this node has attributes, if it is an element. Otherwise, it returns FALSE. Note that for nodes that are not elements, it always returns FALSE.

Syntax

boolean hasAttributes() const;

Returns

(boolean) TRUE is this node is an element and has attributes


hasChildNodes()

Tests if this node has children. Only Element, Document, DTD, and DocumentFragment nodes may have children.

Syntax

boolean hasChildNodes() const;

Returns

(boolean) TRUE if this node has any children


insertBefore()

Inserts the node newChild before the existing child node refChild in this node. refChild must be a child of this node. If newChild is a DocumentFragment, all of its children are inserted (in the same order) before refChild; the DocumentFragment node itself is not. If newChild is already in the DOM tree, it is first removed from its current position.

Syntax

Node* insertBefore( 
   NodeRef& newChild, 
   NodeRef& refChild)
throw (DOMException);
Parameter Description
newChild
new node
refChild
reference node

Returns

feature
package name of feature
version
version of package

Returns

(boolean) TRUE is specified feature is supported


markToDelete()

Syntax

void markToDelete();

normalize()

"Normalizes" the subtree rooted at an element, merges adjacent Text nodes children of elements. Note that adjacent Text nodes will never be created during a normal parse, only after manipulation of the document with DOM calls.

Syntax

void normalize();

removeChild()

Removes the node from this node's list of children and returns it. The node is orphaned; its parent will be NULL after removal.

Syntax

Node* removeChild( 
   NodeRef& oldChild) 
throw (DOMException);
Parameter Description
oldChild
old node

Returns

(Node*) node removed


replaceChild()

Replaces the child node oldChild with the new node newChild in this node's children list, and returns oldChild (which is now orphaned, with a NULL parent). If newChild is a DocumentFragment, all of its children are inserted in place of oldChild; the DocumentFragment node itself is not. If newChild is already in the DOM tree, it is first removed from its current position.

Syntax

Node* replaceChild( 
   NodeRef& newChild, 
   NodeRef& oldChild)
throw (DOMException);
Parameter Description
newChild
new node
oldChild
old node

Returns

(Node*) the node replaced


resetNode()

This function resets NodeRef to reference Node given as an argument

Syntax

void resetNode( 
   Node* nptr);
Parameter Description
nptr
reference node


setNodeValue()

Sets a node's value (character data) as a NULL-terminated string. Does not allow setting the value to NULL. Only Attr, CDATA, Comment, ProcessingInstruction, and Text nodes have values. Trying to set the value of another kind of node is a no-op. The new value must be in the data encoding! It is not verified, converted, or checked. The value is not copied, its pointer is just stored. The user is responsible for persistence and freeing of that data.

It throws the NO_MODIFICATION_ALLOWED_ERR exception, if no modifications are allowed, or UNDEFINED_ERR, with an appropriate Oracle XML error code (see xml.h), in the case of an implementation defined error.

Syntax

void setNodeValue( 
   oratext* data) 
throw (DOMException);
Parameter Description
data
new value for node


setPrefix()

Sets the namespace prefix of this node (as NULL-terminated string). Does not verify the prefix is defined! And does not verify that the prefix is in the current data encoding. Just causes a new qualified name to be formed from the new prefix and the old local name.

It throws the NO_MODIFICATION_ALLOWED_ERR exception, if no modifications are allowed. Or it throws NAMESPACE_ERR if the namespaceURI of this node is NULL, or if the specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", or if this node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from "http://www.w3.org/2000/xmlns/". Note that the INVALID_CHARACTER_ERR exception is never thrown since it is not checked how the prefix is formed

Syntax

void setPrefix( 
   oratext* prefix) 
throw (DOMException);
Parameter Description
prefix
new namespace prefix


~NodeRef()

This is the default destructor. It cleans the reference to the node and, if the node is marked for deletion, deletes the node. If the node was marked for deep deletion, the tree under the node is also deleted (deallocated). It is usually called by the environment. But it can be called by the user directly if necessary.

Syntax
