Class ElementOverNodeInfo

Implemented Interfaces:
Element, Node
public class ElementOverNodeInfo
extends NodeOverNodeInfo
implements Element
This class is an implementation of the DOM Element class that wraps a Saxon NodeInfo representation of an element node.

The class provides read-only access to the tree; methods that request updates all fail with an UnsupportedOperationException.

Note that contrary to the DOM specification, this implementation does not expose namespace declarations as attributes.

Method Details

getAttribute

public String getAttribute(String name)
Retrieves an attribute value by name. This implementation does not expose namespace nodes as attributes.
Parameters:
name - The QName of the attribute to retrieve.
Returns:
The Attr value as a string, or the empty string if that attribute does not have a specified or default value.

getAttributeNS

public String getAttributeNS(String namespaceURI,
                             String localName)
Retrieves an attribute value by local name and namespace URI. This implementation does not expose namespace nodes as attributes.
Parameters:
namespaceURI - The namespace URI of the attribute to retrieve.
localName - The local name of the attribute to retrieve.
Returns:
The Attr value as a string, or the empty string if that attribute does not have a specified or default value.
Since:
DOM Level 2

getAttributeNode

public Attr getAttributeNode(String name)
Retrieves an attribute node by name. This implementation does not expose namespace nodes as attributes.
To retrieve an attribute node by qualified name and namespace URI, use the getAttributeNodeNS method.
Parameters:
name - The name (nodeName ) of the attribute to retrieve.
Returns:
The Attr node with the specified name ( nodeName ) or null if there is no such attribute.

getAttributeNodeNS

public Attr getAttributeNodeNS(String namespaceURI,
                               String localName)
Retrieves an Attr node by local name and namespace URI. This implementation does not expose namespace nodes as attributes.
Parameters:
namespaceURI - The namespace URI of the attribute to retrieve.
localName - The local name of the attribute to retrieve.
Returns:
The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute.
Since:
DOM Level 2

getElementsByTagName

public NodeList getElementsByTagName(String name)
Returns a NodeList of all descendant Elements with a given tag name, in document order.
Parameters:
name - The name of the tag to match on. The special value "*" matches all tags.
Returns:
A list of matching Element nodes.

getElementsByTagNameNS

public NodeList getElementsByTagNameNS(String namespaceURI,
                                       String localName)
            throws DOMException
Returns a NodeList of all the descendant Elements with a given local name and namespace URI in document order.
Parameters:
namespaceURI - The namespace URI of the elements to match on. The special value "*" matches all namespaces.
localName - The local name of the elements to match on. The special value "*" matches all local names.
Returns:
A new NodeList object containing all the matched Elements.
Since:
DOM Level 2

getSchemaTypeInfo

public TypeInfo getSchemaTypeInfo()
Get the schema type information for this node.
Returns:
the type information. Returns null for an untyped node.

getTagName

public String getTagName()
The name of the element (DOM interface).

hasAttribute

public boolean hasAttribute(String name)
Returns true when an attribute with a given name is specified on this element or has a default value, false otherwise. This implementation does not expose namespace nodes as attributes.
Parameters:
