Document Object Model (DOM)

An XML document can be viewed as a tree whose nodes consisting of information between start-tags and end-tags. This tree representation, or the Document Object Model (DOM), is formed in memory when the XML parser parses a document. The DOM APIs are contained in the oracle.xml.parser.v2 package.

Parameter Description

setAttribute()

Description

Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute. This method is namespace unaware and hence wont result in update of namespace table if a new attr is added through this method. Throws DOMException:

Syntax

public void setAttribute( String name,
                          String value);

Parameter Description

name

The name of the attribute to create or alter.

value

Value to set in string form.

setAttributeNode()

Description

Adds a new attribute. If an attribute with that name is already present in the element, it is replaced by the new one. If the newAttr attribute replaces an existing attribute with the same name, the previously existing Attr node is returned, otherwise null is returned. Throws DOMException:

Syntax

public org.w3c.dom.Attr setAttributeNode ( org.w3c.dom.Attr newAttr);

Parameter Description

newAttr

Attribute to be added to the attribute list.

setAttributeNodeNS()

Description

Adds a new attribute. Throws DOMException:

The options are described in the following table.

Syntax Description

public org.w3c.dom.Attr

setAttributeNodeNS(

org.w3c.dom.Attr newAttr);

Adds and returns a new attribute node. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one.

public void setAttributeNS(

String namespaceURI,

String qualifiedName,

String value);

Constructs a new attribute node from nemespaceURI, qualifiedName, and value, and adds it. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter. This value is a simple string; it is not parsed as it is being set. Therefore, any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out.


Parameter Description

newAttr

Attribute to be added to the attribute list.

namespaceURI

Namespace of the attribute to be added.

localName

Local name of the attribute to be added.

value

Value of the attribute to be added.

XMLNode Class


Description of XMLNode

Implements the DOM Node interface and serves as the primary datatype for the entire Document Object Model. It represents a single node in the document tree.

The attributes nodeName, nodeValue and attributes are included as a mechanism to get at node information without casting down to the specific derived instance. In cases where there is no obvious mapping of these attributes for a specific nodeType (for example, nodeValue for an Element or attributes for a Comment), this returns null. Note that the derived classes may contain additional and more convenient mechanisms to get and set the relevant information. This DOM Nodes extending XMLNode instead of XMLNSNode have fixed Nodename defined by DOM specification. Also only node that cannot have child nodes extend this class.

Implemented Interfaces of XMLText

java.io.Externalizable, java.io.Serializable

Methods of XMLText

Table 2-26 Summary of Methods of XMLText  
Method Description

XMLText()

Creates an instance of XMLText.

addText()

Adds text to the data of the text node.

getData()

Returns the character data of the node that implements this interface.

getNodeName()

Returns the name of the XMLText Node.

getNodeType()

Returns a type of node representing the type of the underlying object.

getNodeValue()

Returns String value of this text node.

isWhiteSpaceNode()

Checks if the text node is a whitespace node.

readExternal()

Reads the information written in the compressed stream by writeExternal method and restores the object correspondingly.

reportSAXEvents()

Reports SAX Events from a DOM Tree.

splitText()

Breaks Text node into two Text nodes at specified offset.

writeExternal()

Saves the state of the object by creating a binary compressed stream with information about this object.

XMLText()

Description

Default constructor. Note that this constructor is used only during deserialization/decompression of this DOM node. In order to deserialize this node to construct the DOM node from the serialized/ compressed stream, it is required to create a handle of the object.

Syntax

public  XMLText();

addText()

Description

Adds text to the data of the text node, similar to appendData.

Syntax

public void addText( char[] ch,
                     int start,
                     int length);

Parameter Description

ch

char array to be appended

start

start index

length

length of the char array

getData()

Description

Returns the character data of the node that implements this interface. The DOM implementation may not put arbitrary limits on the amount of data that may be stored in a Text node. However, implementation limits may mean that the entirety of a node's data may not fit into a single DOMString. In such cases, the user may call substringData to retrieve the data in appropriately sized pieces.

Throws DOMException:

Syntax

public String getData();

getNodeName()

Description

Returns the name of the XMLText Node.

Syntax

public String getNodeName();

getNodeType()

Description

Returns a type of node representing the type of the underlying object.

Syntax

public short getNodeType();

getNodeValue()

Description

Returns String value of this text node. Throws DOMException if any error occurs when retrieving the value.

Syntax

public String getNodeValue();

isWhiteSpaceNode()

Description

Checks if the text node is a whitespace node.

Syntax

public boolean isWhiteSpaceNode();

readExternal()

Description

Reads the information written in the compressed stream by writeExternal method and restores the object correspondingly. This method is called if XMLText object is deserialized (or read) as an independent node and not called from some other DOM nodeThrows the following exceptions:

Syntax

public void readExternal( java.io.ObjectInput in);

Parameter Description

in

The ObjectInput stream used for reading the compressed stream

reportSAXEvents()

Description

Reports SAX Events from a DOM Tree. Throws SAXException.

Syntax

public void reportSAXEvents(org.xml.sax.ContentHandler cntHandler);

Parameter Description

cntHandler

Content handler.

splitText()

Description

Breaks Text node into two Text nodes at specified offset, so they are both siblings, and the node only contains content up to the offset. Returns the new Text node. New node inserted as next sibling contains all content at and after the offset point.

Throws DOMException:

Syntax

public org.w3c.dom.Text splitText( int offset);

Parameter Description

offset

Offset at which to split, starting from 0

writeExternal()

Description

Saves the state of the object by creating a binary compressed stream with information about this object. Throws IOException when there is an exception while writing the compressed stream.

Syntax

public void writeExternal( java.io.ObjectOutput out);

Parameter Description

out

The ObjectOutput stream used to write the compressed stream.
