#local_name ⇒ Object

localName of type DOMString, readonly, introduced in DOM Level 2

Returns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes 
created with a DOM Level 1 method, such as Document.createElement(), 
this is always null.

def local_name
  qname_arr = self.node_name.split(/:/u)
  return qname_arr[-1]
end

#namespace_uri ⇒ Object

namespaceURI of type DOMString, readonly, introduced in DOM Level 2

The namespace URI of this node, or null if it is unspecified (see XML Namespaces).
This is not a computed value that is the result of a namespace lookup based on 
an examination of the namespace declarations in scope. 
It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and 
nodes created with a DOM Level 1 method, such as Document.createElement(), 
this is always null.

Note: Per the Namespaces in XML Specification [XML Namespaces] an attribute 
      does not inherit its namespace from the element it is attached to. 
      If an attribute is not explicitly given a namespace, it simply has 
      no namespace.

#prefix ⇒ Object

prefix of type DOMString, introduced in DOM Level 2

The namespace prefix of this node, or null if it is unspecified. 
  #=> このノードの名前空間接頭辞, または null (指定されていない場合) です.
When it is defined to be null, setting it has no effect, including if the node is read-only.
  #=> null と明示されている場合, およびノードが読み取り専用の場合は, 値の代入は何の効果もありません.  
Note that setting this attribute, when permitted, changes the nodeName attribute, 
which holds the qualified name, as well as the tagName and name attributes of the Element 
and Attr interfaces, when applicable.
  #=> (代入可能な場合に) 値の代入を行うと, nodeName 属性 (qualified name を保持している) が変化します.
  #=> Element インターフェイスの tagName 属性や Attr インターフェイスの name 属性も同様です. (それらに応用可能な場合)
Setting the prefix to null makes it unspecified, setting it to an empty string is implementation dependent.
Note also that changing the prefix of an attribute that is known to have a default value, 
does not make a new attribute with the default value and the original prefix appear, 
since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created 
with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Exceptions on setting
  DOMException
    INVALID_CHARACTER_ERR:
      Raised if the specified prefix contains an illegal character according to the XML version 
      in use specified in the Document.xmlVersion attribute.
    NO_MODIFICATION_ALLOWED_ERR: 
      Raised if this node is readonly.
    NAMESPACE_ERR: 
      Raised if the specified prefix is malformed per the Namespaces in XML specification, 
      if the namespaceURI of this node is null, if the specified prefix is "xml" and 
      the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", 
      if this node is an attribute and the specified prefix is "xmlns" and 
      the namespaceURI of this node is different from "http://www.w3.org/2000/xmlns/", 
      or if this node is an attribute and the qualifiedName of this node is "xmlns" [XML Namespaces].
