TDOMElement = class(TDOMNode_NS)

Inheritance

Description

TDOMElement is a TDOMNode_NS descendant that implements the DOM Element interface from the DOM specification. TDOMElement represents an element in an HTML or XML document. It inherits the capabilities defined in ancestor classes, and provides additional methods and properties need for the DOM Element interface.

Methods are provided to access Attributes using the Node interface defined in TDOMNode, or as a simple string value. Namespaces are supported for both the element and its attributes. The Normalize method is overridden to include normalization for values in the Attributes property.

Properties

`TagName`	public	The qualified name used as the Tag name for the DOM Element.
`AttribStrings`	public	Provides indexed access to Attributes and their value as a String.

Methods

`GetNodeType`	protected	Gets the value for the NodeType property.
`GetAttributes`	protected	Gets the value for the Attributes property.
`AttachDefaultAttrs`	protected	Creates attribute nodes with the default attribute values in a namespaced DOM Element.
`InternalLookupPrefix`	protected	Gets the Namespace Prefix used for the specified Namespace URI.
`RestoreDefaultAttr`	protected	Restores the specified default attribute name and value in the DOM Element.
`Destroy`	public	Destructor for the class instance.
`CloneNode`	public	Creates a DOM node that is a copy of the DOM Element.
`IsEmpty`	public	Indicates if the DOM Element does not have any content.
`Normalize`	public	Performs normalization for Text nodes and Attributes in the DOM Element.
`GetAttribute`	public	Gets the value for the AttribStrings property.
`SetAttribute`	public	Sets the value in the AttribStrings property.
`RemoveAttribute`	public	Removes the DOM Attribute with the specified name.
`GetAttributeNode`	public	Gets the DOM Attribute node with the specified name.
`SetAttributeNode`	public	Stores the new DOM Attribute node to an existing Attribute with the same name.
`RemoveAttributeNode`	public	Removes the specified DOM Attribute node from the Attributes for the Element.
`GetElementsByTagName`	public	Gets a list of DOM nodes with the specified name in the sub-tree for the Element.
`GetAttributeNS`	public	Gets the value for an Attribute with the specified Namespace URI and local name.
`SetAttributeNS`	public	Sets the value for the DOM Attribute with the specified Namespace URI and qualified name.
`RemoveAttributeNS`	public	Removes the DOM Attribute with the specified Namespace URI and local name.
`GetAttributeNodeNS`	public	Gets the DOM Attribute node with the specified Namespace URI and local name.
`SetAttributeNodeNS`	public	Stores the new DOM Attribute node in an existing Namespaced Attribute node.
`GetElementsByTagNameNS`	public	Gets a Node list with Elements having the specified Namespace URI and local name.
`hasAttribute`	public	Indicates if the Attributes property contains an item with the specified name.
`hasAttributeNS`	public	Indicates if Attributes contains an attribute with the specified Namespace URI and local name.
`HasAttributes`	public	Indicates if the Attributes property contains DOM Attribute nodes.
