public class HTMLElementImpl extends org.apache.xerces.dom.ElementImpl implements 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

      public Attr getAttributeNode(String attrName)
      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 interface Element
      Overrides:
      getAttributeNode in class org.apache.xerces.dom.ElementImpl

    • getAttributeNodeNS

      public Attr getAttributeNodeNS(String namespaceURI, String localName)
      Description copied from class: org.apache.xerces.dom.ElementImpl
      Retrieves an Attr node by local name and namespace URI.
      Specified by:
      getAttributeNodeNS in interface Element
      Overrides:
      getAttributeNodeNS in class org.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

      public String getAttribute(String attrName)
      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 interface Element
      Overrides:
      getAttribute in class org.apache.xerces.dom.ElementImpl

    • getAttributeNS

      public String getAttributeNS(String namespaceURI, String localName)
      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 interface Element
      Overrides:
      getAttributeNS in class org.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

      public final NodeList getElementsByTagName(String tagName)
      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 interface Element
      Overrides:
      getElementsByTagName in class org.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

      public final NodeList getElementsByTagNameNS(String namespaceURI, String localName)
      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 interface Element
      Overrides:
      getElementsByTagNameNS in class org.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 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.
