        Yield (element, attribute, link, pos), where attribute may be None
        (indicating the link is in the text).  ``pos`` is the position
        where the link occurs; often 0, but sometimes something else in
        the case of links in stylesheets or style tags.

        Note: <base href> is *not* taken into account in any way.  The
        link you get is exactly the link in the document.

        Note: multiple links inside of a single text string or
        attribute value are returned in reversed order.  This makes it
        possible to replace or delete them from the text string value
        based on their reported text positions.  Otherwise, a
        modification at one text position can change the positions of
        links reported later on.

        Rewrite all the links in the document.  For each link
        ``link_repl_func(link)`` will be called, and the return value
        will replace the old link.

        Note that links may not be absolute (unless you first called
        ``make_links_absolute()``), and may be internal (e.g.,
        ``'#anchor'``).  They can also be values like
        ``'mailto:email'`` or ``'javascript:expr'``.

        If you give ``base_href`` then all links passed to
        ``link_repl_func()`` will take that into account.

        If the ``link_repl_func`` returns None, the attribute or
        tag text will be removed completely.

    the function takes either an element or an HTML string.  It

    The first item in the list may be a string.
    If no_leading_text is true, then it will be an error if there is
    leading text, and it will always be a list of only elements.

    Parses a single HTML element; it is an error if there is more than
    one element, or if anything but whitespace precedes or follows the
    element.

    If ``create_parent`` is true (or is a tag name) then a parent node
    will be created to encapsulate the HTML in a single element.  In this
    case, leading or trailing text is also allowed, as are multiple elements
    as result of the parsing.

    Passing a ``base_url`` will set the document's ``base_url`` attribute

    Helper function to submit a form.  Returns a file-like object, as from
    ``urllib.urlopen()``.  This object also has a ``.geturl()`` function,
    which shows the URL if there were any redirects.

    You can use this like::

        form = doc.forms[0]
        form.inputs['foo'].value = 'bar' # etc
        response = form.submit()
        doc = parse(response)
        doc.make_links_absolute(response.geturl())

    To change the HTTP requester, pass a function as ``open_http`` keyword
    argument that opens the URL for you.  The function must have the following
    signature::

        open_http(method, URL, values)

    The action is one of 'GET' or 'POST', the URL is the target URL as a
    string, and the values are a sequence of ``(name, value)`` tuples with the
    form data.

    An accessor that represents all the input fields in a form.

    You can get fields by name from this, with
    ``form.inputs['field_name']``.  If there are a set of checkboxes
    with the same name, they are returned as a list (a `CheckboxGroup`
    which also allows value setting).  Radio inputs are handled
    similarly.

    You can also iterate over this to get all input elements.  This
    won't return the same thing as if you get all the names, as
    checkboxes and radio elements are returned individually.

    Represents an ``<input>`` element.

    You can get the type with ``.type`` (which is lower-cased and
    defaults to ``'text'``).

    Also you can get and set the value with ``.value``

    Checkboxes and radios have the attribute ``input.checkable ==
    True`` (for all others it is false) and a boolean attribute
    ``.checked``.

    cCs(|jr|jr|�d�pdSdS|�d�S)z�
        Get/set the value of this element, using the ``value`` attribute.

        Also, if this is a checkbox and it has no value, this defaults
        to ``'on'``.  If it is a checkbox or radio that is not
        checked, this returns None.

Return an HTML string representation of the document.

    Note: if include_meta_content_type is true this will create a
    ``<meta http-equiv="Content-Type" ...>`` tag in the head;
    regardless of the value of include_meta_content_type any existing
    ``<meta http-equiv="Content-Type" ...>`` tag will be removed

    The ``encoding`` argument controls the output encoding (defaults to
    ASCII, with &#...; character references for any characters outside
    of ASCII).  Note that you can pass the name ``'unicode'`` as
    ``encoding`` argument to serialise to a Unicode string.

    The ``method`` argument defines the output method.  It defaults to
    'html', but can also be 'xml' for xhtml output, or 'text' to
    serialise to plain text without markup.

    To leave out the tail text of the top-level element that is being
    serialised, pass ``with_tail=False``.

    The ``doctype`` option allows passing in a plain string that will
    be serialised before the XML tree.  Note that passing in non
    well-formed content here will make the XML output non well-formed.
    Also, an existing doctype in the document tree will not be removed
    when serialising an ElementTree instance.

    Example::

        >>> from lxml import html
        >>> root = html.fragment_fromstring('<p>Hello<br>world!</p>')

        >>> html.tostring(root)
        b'<p>Hello<br>world!</p>'
        >>> html.tostring(root, method='html')
        b'<p>Hello<br>world!</p>'

        >>> html.tostring(root, method='xml')
        b'<p>Hello<br/>world!</p>'

        >>> html.tostring(root, method='text')
        b'Helloworld!'

        >>> html.tostring(root, method='text', encoding='unicode')
        u'Helloworld!'

        >>> root = html.fragment_fromstring('<div><p>Hello<br>world!</p>TAIL</div>')
        >>> html.tostring(root[0], method='text', encoding='unicode')
        u'Helloworld!TAIL'

        >>> html.tostring(root[0], method='text', encoding='unicode', with_tail=False)
        u'Helloworld!'

        >>> doc = html.document_fromstring('<p>Hello<br>world!</p>')
        >>> html.tostring(doc, method='html', encoding='unicode')
        u'<html><body><p>Hello<br>world!</p></body></html>'

        >>> print(html.tostring(doc, method='html', encoding='unicode',
        ...          doctype='<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'

    Note that this parser is not really XHTML aware unless you let it
    load a DTD that declares the HTML entities.  To do this, make sure
    you have the XHTML DTDs installed in your catalogs, and create the
    parser like this::

        >>> parser = XHTMLParser(load_dtd=True)

    If you additionally want to validate the document, use this::
