public class HTMLElementImpl extends ElementImpl implements org.w3c.dom.html.HTMLElement
Implements an HTML-specific element, anElement
that will only appear inside HTML documents. This element extendsElementImpl
by adding methods for directly manipulating HTML-specific attributes. All HTML elements gain access to theid
,title
,lang
,dir
andclass
attributes. Other elements add their own specific attributes.- See Also:

getInteger
int getInteger(java.lang.String value)
Convenience method used to translate an attribute value into an integer value. Returns the integer value or zero if the attribute is not a valid numeric string.- Parameters:
value
- The value of the attribute- Returns:
- The integer value, or zero if not a valid numeric string
-
getBinary
boolean getBinary(java.lang.String attrName)
Convenience method used to translate an attribute value into a boolean value. If the attribute has an associated value (even an empty string), it is set and true is returned. If the attribute does not exist, false is returned.- Parameters:
attrName
- The name of the attribute- Returns:
- True or false depending on whether the attribute has been set
-
setAttribute
void setAttribute(java.lang.String name, boolean value)
Convenience method used to set a boolean attribute. If the value is true, the attribute is set to an empty string. If the value is false, the attribute is removed. HTML 4.0 understands empty strings as set attributes.- Parameters:
name
- The name of the attributevalue
- The value of the attribute
-
getAttributeNode
public org.w3c.dom.Attr getAttributeNode(java.lang.String attrName)
Description copied from class: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 interfaceorg.w3c.dom.Element
- Overrides:
getAttributeNode
in classElementImpl
-
getAttributeNodeNS
public org.w3c.dom.Attr getAttributeNodeNS(java.lang.String namespaceURI, java.lang.String localName)
Description copied from class:ElementImpl
Retrieves an Attr node by local name and namespace URI.- Specified by:
getAttributeNodeNS
in interfaceorg.w3c.dom.Element
- Overrides:
getAttributeNodeNS
in classElementImpl
- 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
public java.lang.String getAttribute(java.lang.String attrName)
Description copied from class: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 interfaceorg.w3c.dom.Element
- Overrides:
getAttribute
in classElementImpl
-
getAttributeNS
public java.lang.String getAttributeNS(java.lang.String namespaceURI, java.lang.String localName)
Description copied from class:ElementImpl
Introduced in DOM Level 2.Retrieves an attribute value by local name and namespace URI.
- Specified by:
getAttributeNS
in interfaceorg.w3c.dom.Element
- Overrides:
getAttributeNS
in classElementImpl
- 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
public final org.w3c.dom.NodeList getElementsByTagName(java.lang.String tagName)
Description copied from class: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 interfaceorg.w3c.dom.Element
- Overrides:
getElementsByTagName
in classElementImpl
- 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
public final org.w3c.dom.NodeList getElementsByTagNameNS(java.lang.String namespaceURI, java.lang.String localName)
Description copied from class: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 interfaceorg.w3c.dom.Element
- Overrides:
getElementsByTagNameNS
in classElementImpl
- 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.
-
capitalize
java.lang.String capitalize(java.lang.String value)
Convenience method used to capitalize a one-off attribute value before it is returned. For example, the align values "LEFT" and "left" will both return as "Left".- Parameters:
value
- The value of the attribute- Returns:
- The capitalized value
-
getCapitalized
java.lang.String getCapitalized(java.lang.String attrname)
Convenience method used to capitalize a one-off attribute value before it is returned. For example, the align values "LEFT" and "left" will both return as "Left".- Parameters:
attrname
- The name of the attribute- Returns:
- The capitalized value
-
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.
