public class HTMLElementImpl
extends org.apache.xerces.dom.ElementImpl
implements org.w3c.dom.html.HTMLElement
Implements an HTML-specific element, an
Element
that
will only appear inside HTML documents. This element extends ElementImpl
by adding methods for directly
manipulating HTML-specific attributes. All HTML elements gain access to
the id
, title
, lang
,
dir
and class
attributes. Other elements
add their own specific attributes.

getAttributeNode
Description copied from class:org.apache.xerces.dom.ElementImpl
Look up a single Attribute by name. Returns the Attribute Node, so its complete child tree is available. This could be important in XML, where the string rendering may not be sufficient information.If no matching attribute is available, returns null.
- Specified by:
getAttributeNode
in interfaceElement
- Overrides:
getAttributeNode
in classorg.apache.xerces.dom.ElementImpl
-
getAttributeNodeNS
Description copied from class:org.apache.xerces.dom.ElementImpl
Retrieves an Attr node by local name and namespace URI.- Specified by:
getAttributeNodeNS
in interfaceElement
- Overrides:
getAttributeNodeNS
in classorg.apache.xerces.dom.ElementImpl
- Parameters:
namespaceURI
- The namespace URI of the attribute to retrieve.localName
- The local name of the attribute to retrieve.- Returns:
- Attr The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute.
-
getAttribute
Description copied from class:org.apache.xerces.dom.ElementImpl
Look up a single Attribute by name. Returns the Attribute's string value, or an empty string (NOT null!) to indicate that the name did not map to a currently defined attribute.Note: Attributes may contain complex node trees. This method returns the "flattened" string obtained from Attribute.getValue(). If you need the structure information, see getAttributeNode().
- Specified by:
getAttribute
in interfaceElement
- Overrides:
getAttribute
in classorg.apache.xerces.dom.ElementImpl
-
getAttributeNS
Description copied from class:org.apache.xerces.dom.ElementImpl
Introduced in DOM Level 2.Retrieves an attribute value by local name and namespace URI.
- Specified by:
getAttributeNS
in interfaceElement
- Overrides:
getAttributeNS
in classorg.apache.xerces.dom.ElementImpl
- Parameters:
namespaceURI
- The namespace URI of the attribute to retrieve.localName
- The local name of the attribute to retrieve.- Returns:
- String The Attr value as a string, or empty string if that attribute does not have a specified or default value.
-
getElementsByTagName
Description copied from class:org.apache.xerces.dom.ElementImpl
Returns a NodeList of all descendent nodes (children, grandchildren, and so on) which are Elements and which have the specified tag name.Note: NodeList is a "live" view of the DOM. Its contents will change as the DOM changes, and alterations made to the NodeList will be reflected in the DOM.
- Specified by:
getElementsByTagName
in interfaceElement
- Overrides:
getElementsByTagName
in classorg.apache.xerces.dom.ElementImpl
- Parameters:
tagName
- The type of element to gather. To obtain a list of all elements no matter what their names, use the wild-card tag name "*".- See Also:
-
DeepNodeListImpl
-
getElementsByTagNameNS
Description copied from class:org.apache.xerces.dom.ElementImpl
Introduced in DOM Level 2.Returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the Document tree, starting from this node.
- Specified by:
getElementsByTagNameNS
in interfaceElement
- Overrides:
getElementsByTagNameNS
in classorg.apache.xerces.dom.ElementImpl
- Parameters:
namespaceURI
- The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName.localName
- The local name of the elements to match on. The special value "*" matches all local names.- Returns:
- NodeList A new NodeList object containing all the matched Elements.
-
getForm
public org.w3c.dom.html.HTMLFormElement getForm()Convenience method returns the form in which this form element is contained. This method is exposed for form elements through the DOM API, but other elements have no access to it through the API.
