The <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> interface is the primary datatype for the entire Document Object Model.
<p>
It represents a single node in the document tree. While all objects implementing the <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> interface expose methods for dealing with children, not all objects implementing the <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> interface may have children. For example, <code>DOMText</code> nodes may not have children, and adding children to such nodes results in a <code>DOMException</code> being raised. <p>
The attributes <code>nodeName</code>, <code>nodeValue</code> and <code>attributes</code> are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specific <code>nodeType</code> (e.g., <code>nodeValue</code> for an <code>DOMElement</code> or <code>attributes</code> for a <code>DOMComment</code> ), this returns <code>null</code>. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information. <p>
The values of <code>nodeName</code>, <code>nodeValue</code>, and <code>attributes</code> vary according to the node type as follows: <tableborder="1"cellspacing="3"cellpadding="3">

This function serves as a generic copy constructor for nodes.<p>

Cloning an <code>DOMElement</code> 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 <code>DOMText</code> node.

Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: <code>nodeName</code>, <code>localName</code>, <code>namespaceURI</code>, <code>prefix</code>, <code>nodeValue</code> , <code>baseURI</code>. This is: they are both <code>null</code>, or they have the same length and are character for character identical. The <code>attributes</code><code>DOMNamedNodeMaps</code> are equal.

This is: they are both <code>null</code>, or they have the same length and contain equal nodes at the same index. This is true for <code>DOMAttr</code> nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared. <br>
For two <code>DOMDocumentType</code> nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: <code>publicId</code>, <code>systemId</code>, <code>internalSubset</code>.The <code>entities</code><code>DOMNamedNodeMaps</code> are equal.The <code>notations</code><code>DOMNamedNodeMaps</code> are equal. <br>
On the other hand, the following do not affect equality: the <code>ownerDocument</code> attribute, the <code>specified</code> attribute for <code>DOMAttr</code> nodes, the <code>isWhitespaceInElementContent</code> attribute for <code>DOMText</code> nodes, as well as any user data or event listeners registered on the nodes.<p>

This method provides a way to determine whether two <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> references returned by the implementation reference the same object. When two <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.<p>

Puts all <code>DOMText</code> nodes in the full depth of the sub-tree underneath this <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code>, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates <code>DOMText</code> nodes, i.e., there are neither adjacent <code>DOMText</code> nodes nor empty <code>DOMText</code> nodes.
<p>
This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used. <p>
<b>Note:</b> In cases where the document contains <code>DOMCDATASections</code>, the normalize operation alone may not be sufficient, since XPointers do not differentiate between <code>DOMText</code> nodes and <code>DOMCDATASection</code> nodes.<p>
Called to indicate that this <aclass="el"href="classNode.html">Node</a> (and its associated children) is no longer in use and that the implementation may relinquish any resources associated with it and its associated children.
<p>
If this is a document, any nodes it owns (created by DOMDocument::createXXXX()) are also released.<p>
Access to a released object will lead to unexpected result.<p>

Replaces the child node <code>oldChild</code> with <code>newChild</code> in the list of children, and returns the <code>oldChild</code> node.
<p>
If <code>newChild</code> is a <code>DOMDocumentFragment</code> object, <code>oldChild</code> is replaced by all of the <code>DOMDocumentFragment</code> children, which are inserted in the same order.<p>

Any node which can have a nodeValue will also accept requests to set it to a string. The exact response to this varies from node to node -- Attribute, for example, stores its values in its children and has to replace them with a new Text holding the replacement value.<p>
For most types of <aclass="el"href="classNode.html">Node</a>, value is null and attempting to set it will throw DOMException(NO_MODIFICATION_ALLOWED_ERR). This will also be thrown if the node is read-only. <dlcompact><dt><b>See also:</b></dt><dd><aclass="el"href="classxercesc_1_1DOMNode.html#91c52c0624325ac9c9e176e944c2e179">getNodeValue</a></dd></dl>
Note that setting this attribute, when permitted, changes the <code>nodeName</code> attribute, which holds the <em>qualified name</em>, as well as the <code>tagName</code> and <code>name</code> attributes of the <code>DOMElement</code> and <code>DOMAttr</code> interfaces, when applicable. <p>
Note also that changing the prefix of an attribute, that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the <code>namespaceURI</code> and <code>localName</code> do not change.<p>

This attribute removes any possible children this node may have and, if the new string is not empty or null, replaced by a single <code>DOMText</code> node containing the string this attribute is set to.

The object can later be retrieved from this node by calling <code>getUserData</code> with the same key.<p>
Deletion of the user data remains the responsibility of the application program; it will not be automatically deleted when the nodes themselves are reclaimed.<p>
Both the parameter <code>data</code> and the returned object are void pointer, it is applications' responsibility to keep track of their original type. Casting them to the wrong type may result unexpected behavior.<p>
