class Element:
    """Represents an XML element node.

    An Element contains a series of attributes (name/value pairs), content
    (character data), and other child Element objects. When building a document
    with markup (such as HTML or XML), use this object as the starting point.

    Element objects fully support XML Namespaces. The fully qualified name of
    the XML Element it represents is stored in the C{uri} and C{name}
    attributes, where C{uri} holds the namespace URI. There is also a default
    namespace, for child elements. This is stored in the C{defaultUri}
    attribute. Note that C{''} means the empty namespace.

    Serialization of Elements through C{toXml()} will use these attributes
    for generating proper serialized XML. When both C{uri} and C{defaultUri}
    are not None in the Element and all of its descendents, serialization
    proceeds as expected:

      >>> from twisted.words.xish import domish
      >>> root = domish.Element(('myns', 'root'))
      >>> root.addElement('child', content='test')
      <twisted.words.xish.domish.Element object at 0x83002ac>
      >>> root.toXml()
      u"<root xmlns='myns'><child>test</child></root>"

    For partial serialization, needed for streaming XML, a special value for
    namespace URIs can be used: L{None}.

    Using L{None} as the value for C{uri} means: this element is in whatever
    namespace inherited by the closest logical ancestor when the complete XML
    document has been serialized. The serialized start tag will have a
    non-prefixed name, and no xmlns declaration will be generated.

    Similarly, L{None} for C{defaultUri} means: the default namespace for my
    child elements is inherited from the logical ancestors of this element,
    when the complete XML document has been serialized.

    To illustrate, an example from a Jabber stream. Assume the start tag of the
    root element of the stream has already been serialized, along with several
    complete child elements, and sent off, looking like this::

      <stream:stream xmlns:stream='http://etherx.jabber.org/streams'
                     xmlns='jabber:client' to='example.com'>
        ...

    Now suppose we want to send a complete element represented by an
    object C{message} created like:

      >>> message = domish.Element((None, 'message'))
      >>> message['to'] = 'user@example.com'
      >>> message.addElement('body', content='Hi!')
      <twisted.words.xish.domish.Element object at 0x8276e8c>
      >>> message.toXml()
      u"<message to='user@example.com'><body>Hi!</body></message>"

    As, you can see, this XML snippet has no xmlns declaration. When sent
    off, it inherits the C{jabber:client} namespace from the root element.
    Note that this renders the same as using C{''} instead of L{None}:

      >>> presence = domish.Element(('', 'presence'))
      >>> presence.toXml()
      u"<presence/>"

    However, if this object has a parent defined, the difference becomes
    clear:

      >>> child = message.addElement(('http://example.com/', 'envelope'))
      >>> child.addChild(presence)
      <twisted.words.xish.domish.Element object at 0x8276fac>
      >>> message.toXml()
      u"<message to='user@example.com'><body>Hi!</body><envelope xmlns='http://example.com/'><presence xmlns=''/></envelope></message>"

    As, you can see, the <presence/> element is now in the empty namespace, not
    in the default namespace of the parent or the streams'.
