The ``E`` Element factory for generating XML documents.

�ElementMakerac��Element generator factory.

Unlike the ordinary Element factory, the E factory allows you to pass in
    more than just a tag and some optional attributes; you can also pass in
    text and other elements.  The text is added as either text or tail
    attributes, and elements are inserted at the right spot.  Some small
    examples::

>>> from lxml import etree as ET
        >>> from lxml.builder import E

>>> ET.tostring(E("tag"))
 '<tag/>'
 >>> ET.tostring(E("tag", "text"))
 '<tag>text</tag>'
 >>> ET.tostring(E("tag", "text", key="value"))
 '<tag key="value">text</tag>'
 >>> ET.tostring(E("tag", E("subtag", "text"), "tail"))
 '<tag><subtag>text</subtag>tail</tag>'

For simple tags, the factory also allows you to write ``E.tag(...)`` instead
    of ``E('tag', ...)``::

>>> ET.tostring(E.tag())
 '<tag/>'
 >>> ET.tostring(E.tag("text"))
 '<tag>text</tag>'
 >>> ET.tostring(E.tag(E.subtag("text"), "tail"))
 '<tag><subtag>text</subtag>tail</tag>'

Here's a somewhat larger example; this shows how to generate HTML
    documents, using a mix of prepared factory functions for inline elements,
    nested ``E.tag`` calls, and embedded XHTML fragments::

# some common inline elements
        A = E.a
        I = E.i
        B = E.b

def CLASS(v):
            # helper function, 'class' is a reserved word
            return {'class': v}

page = (
 E.html(
 E.head(
 E.title("This is a sample document")
 ),
 E.body(
 E.h1("Hello!", CLASS("title")),
 E.p("This is a paragraph with ", B("bold"), " text in it!"),
 E.p("This is another paragraph, with a ",
 A("link", href="http://www.python.org"), "."),
 E.p("Here are some reserved characters: <spam&egg>."),
 ET.XML("And finally, here is an embedded XHTML fragment."),
 )
 )
 )

print ET.tostring(page)

Here's a prettyprinted version of the output from the above script::

<html>
 <head>
 <title>This is a sample document</title>
 </head>
 <body>
 <h1 class="title">Hello!</h1>
 This is a paragraph with bold text in it!
 This is another paragraph, with <a href="http://www.python.org">link</a>.
 Here are some reserved characters: &lt;spam&amp;egg&gt;.
 And finally, here is an embedded XHTML fragment.
 </body>
 </html>

For namespace support, you can pass a namespace map (``nsmap``)
    and/or a specific target ``namespace`` to the ElementMaker class::

>>> E = ElementMaker(namespace="http://my.ns/")
 >>> print(ET.tostring( E.test ))
 <test xmlns="http://my.ns/"/>

>>> E = ElementMaker(namespace="http://my.ns/", nsmap={'p':'http://my.ns/'})
 >>> print(ET.tostring( E.test ))
 <p:test xmlns:p="http://my.ns/"/>
