2 Package Dom APIs for C++

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.

   ub4 count, 
   oratext* data)
throw (DOMException);

offset

count

data

setData()

Sets data for a CharacterData node (type text, comment or CDATA), replacing the old data. The new data is not verified, converted, or checked -- it should be in the data encoding.

Syntax

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

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

Returns

(Node*) New comment node

createDocumentFragment()

Syntax

Node* createDocumentFragment()
throw (DOMException);

Returns

(Node*) new document fragment node

Note that the tag name of an element is case sensitive. This is the non-namespace aware function: the new node will have NULL namespace URI and prefix, and its local name will be the same as its tag name, even if the tag name specified is a qualified name.

Syntax

Node* createElement(
   oratext* tagname)
throw (DOMException);

tagname

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.

Syntax

Node* createElementNS(
   oratext* namespaceURI,
   oratext* qualifiedName)
throw (DOMException);

namespaceURI

qualifiedName

Returns

(Node*) New element node

createEntityReference()

The name is not verified, converted, or checked. The new node is an orphan with no parent. The entity reference name is not copied; its pointer is just stored. The user is responsible for persistence and freeing of that data.

Note that entity reference nodes are never generated by the parser; instead, entity references are expanded as encountered. On output, an entity reference node will turn into a "&name;" style reference.

Syntax

Node* createEntityReference(
   oratext* name)
throw (DOMException);

name

Returns

(Node*) New entity reference node

createProcessingInstruction()

Creates a processing instruction node with the given target and data (which should be in the data encoding). The data may be NULL, but the target is required and cannot be changed.

   oratext* target,
   oratext* data)
throw (DOMException);

target

data

Returns

(Node*) New PI node

The text data is not copied, its pointer is just stored. The user is responsible for persistence and freeing of that data.

Syntax

Node* createTextNode(
   oratext* data)
throw (DOMException);

data

Returns

(Node*) new text node

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);

elementId

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;

tagname

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);

namespaceURI

localName

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 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);

Returns

(NamedNodeMap*) NamedNodeMap of attributes

getChildNodes()

   NodeRef& newChild, 
   NodeRef& refChild)
throw (DOMException);

(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 already in the DOM tree, it is first removed from its current position.

Syntax

Node* replaceChild( 
   NodeRef& newChild, 
   NodeRef& oldChild)
throw (DOMException);

newChild

oldChild

Returns

(Node*) the node replaced

   Node* nptr);

nptr

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)

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);

prefix
