Method Detail

getTagName

public java.lang.String getTagName()

Description copied from interface: org.w3c.dom.Element

The name of the element. For example, in:

 <elementExample 
 id="demo"> ... </elementExample> , 

tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the tagName of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.

Specified by:

getTagName in interface org.w3c.dom.Element

getAttribute

public java.lang.String getAttribute(java.lang.String name)

Description copied from interface: org.w3c.dom.Element

Retrieves an attribute value by name.

Specified by:

getAttribute in interface org.w3c.dom.Element

Parameters:

name - The 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.

getAttributeNode

public org.w3c.dom.Attr getAttributeNode(java.lang.String name)

Description copied from interface: org.w3c.dom.Element

Retrieves an attribute node by name.
To retrieve an attribute node by qualified name and namespace URI, use the getAttributeNodeNS method.

Specified by:

getAttributeNode in interface org.w3c.dom.Element

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.

getElementsByTagName

public org.w3c.dom.NodeList getElementsByTagName(java.lang.String name)

Description copied from interface: org.w3c.dom.Element

Returns a NodeList of all descendant Elements with a given tag name, in the order in which they are encountered in a preorder traversal of this Element tree.

Specified by:

getElementsByTagName in interface org.w3c.dom.Element

Parameters:

name - The name of the tag to match on. The special value "*" matches all tags.

Returns:

Description copied from interface: org.w3c.dom.Element

Retrieves an attribute value by local name and namespace URI.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Specified by:

getAttributeNS in interface org.w3c.dom.Element

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.

                                           java.lang.String localName)

Description copied from interface: org.w3c.dom.Element

Retrieves an Attr node by local name and namespace URI.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Specified by:

getAttributeNodeNS in interface org.w3c.dom.Element

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.

                                                   java.lang.String localName)

Description copied from interface: org.w3c.dom.Element

Returns a NodeList of all the descendant Elements with a given local name and namespace URI in the order in which they are encountered in a preorder traversal of this Element tree.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Specified by:

getElementsByTagNameNS in interface org.w3c.dom.Element

Parameters:

namespaceURI - The namespace URI of the elements to match on. The special value "*" matches all namespaces.

                              java.lang.String localName)

Description copied from interface: org.w3c.dom.Element

Returns true when an attribute with a given local name and namespace URI is specified on this element or has a default value, false otherwise.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Specified by:

hasAttributeNS in interface org.w3c.dom.Element

Parameters:

namespaceURI - The namespace URI of the attribute to look for.

getSchemaTypeInfo

public org.apache.xerces.dom3.TypeInfo getSchemaTypeInfo()

setAttribute

public void setAttribute(java.lang.String name,
                         java.lang.String value)
                  throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Element

Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the setAttributeNS method.

Specified by:

setAttribute in interface org.w3c.dom.Element

Parameters:

name - The name of the attribute to create or alter.

value - Value to set in string form.

Throws:

org.w3c.dom.DOMException - INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

removeAttribute

public void removeAttribute(java.lang.String name)
                     throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Element

Removes an attribute by name. If the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.

Specified by:

removeAttribute in interface org.w3c.dom.Element

Parameters:

name - The name of the attribute to remove.

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

removeAttributeNode

public org.w3c.dom.Attr removeAttributeNode(org.w3c.dom.Attr oldAttr)
                                     throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Element

Removes the specified attribute node. If the removed Attr has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.

Specified by:

removeAttributeNode in interface org.w3c.dom.Element

Parameters:

oldAttr - The Attr node to remove from the attribute list.

Returns:

The Attr node that was removed.

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if oldAttr is not an attribute of the element.

setAttributeNode

public org.w3c.dom.Attr setAttributeNode(org.w3c.dom.Attr newAttr)
                                  throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Element

Adds a new attribute node. If an attribute with that name ( nodeName) is already present in the element, it is replaced by the new one.
To add a new attribute node with a qualified name and namespace URI, use the setAttributeNodeNS method.

Specified by:

setAttributeNode in interface org.w3c.dom.Element

Parameters:

newAttr - The Attr node to add to the attribute list.

Returns:

If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.

Throws:

org.w3c.dom.DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

setAttributeNS

public void setAttributeNS(java.lang.String namespaceURI,
                           java.lang.String qualifiedName,
                           java.lang.String value)
                    throws org.w3c.dom.DOMException

Description copied from interface: org.w3c.dom.Element

Adds a new attribute. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.

Specified by:

setAttributeNS in interface org.w3c.dom.Element

Parameters:

namespaceURI - The namespace URI of the attribute to create or alter.

qualifiedName - The qualified name of the attribute to create or alter.

value - The value to set in string form.

Throws:

org.w3c.dom.DOMException - INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character, per the XML 1.0 specification .
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the qualifiedName is malformed per the Namespaces in XML specification, if the qualifiedName has a prefix and the namespaceURI is null, if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from " http://www.w3.org/XML/1998/namespace", or if the qualifiedName, or its prefix, is "xmlns" and the namespaceURI is different from " http://www.w3.org/2000/xmlns/".
NOT_SUPPORTED_ERR: Always thrown if the current document does not support the "XML" feature, since namespaces were defined by XML.

removeAttributeNS

public void removeAttributeNS(java.lang.String namespaceURI,
                              java.lang.String localName)
