It represents a single node in the document tree. While all objects implementing the <a href="Poco.XML.Node.html" title="class Poco::XML::Node">Node</a> interface expose methods for dealing with children, not all objects implementing the <a href="Poco.XML.Node.html" title="class Poco::XML::Node">Node</a> interface may have children. For example, <a href="Poco.XML.Text.html" title="class Poco::XML::Text">Text</a> nodes may not have children, and adding children to such nodes results in a <a href="Poco.XML.DOMException.html" title="class Poco::XML::DOMException">DOMException</a> being raised. </p> <p>The attributes nodeName, nodeValue and attributes 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 nodeType (e.g., nodeValue for an <a href="Poco.XML.Element.html" title="class Poco::XML::Element">Element</a> or attributes for a <a href="Poco.XML.Comment.html" title="class Poco::XML::Comment">Comment</a>), this returns null. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information. </p> <p>This implementation differs in some ways from the W3C DOM recommendations. For example, the DOM specifies that some methods can return null strings. Instead of null strings, this implementation always returns empty strings. </p> </div> <h2>Inheritance</h2> <p><b>Direct Base Classes: </b><a href="Poco.XML.EventTarget.html" title="class
