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 reservered characters: <spam&egg>."), ET.XML("<p>And finally, here is an embedded XHTML fragment.</p>"), ) ) ) 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> <p>This is a paragraph with <b>bold</b> text in it!</p> <p>This is another paragraph, with <a href="http://www.python.org">link</a>.</p> <p>Here are some reservered characters: <spam&egg>.</p> <p>And finally, here is an embedded XHTML fragment.</p> </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/"/> c s | d k r d | d | _ n d | _ | rA t | � | _ n d | _ | d k rt t | � sh t � | | _ n t j | _ � r� � j � � n i � d � } t � k r� | � t <n t � k r� | � t <n � f d � } t � k r� | � t <n � | _ d S( Nt {t }c S sP y" | d j p d | | d _ Wn' t k rK | j p> d | | _ n Xd S( Ni����t ( t tailt IndexErrort text( t elemt item( ( s2 /usr/lib64/python2.7/site-packages/lxml/builder.pyt add_text� s " c sc | j } xS | j � D]E \ } } t | t � r> | | | <q � t | � d | � | | <q Wd S( N( t attribt itemst isinstancet basestringt typet None( R R R t kt v( t typemap( s2 /usr/lib64/python2.7/site-packages/lxml/builder.pyt add_dict� s ( R t _namespacet dictt _nsmapR t AssertionErrort _makeelementt ETt Elementt copyt strt unicodet _typemap( t selfR t namespacet nsmapt makeelementR R ( ( R s2 /usr/lib64/python2.7/site-packages/lxml/builder.pyt __init__� s, c O se | j j } | j d k r; | d d k r; | j | } n | j | d | j �} | ro | t � | | � n x� | D]� } t | � r� | � } n | t | � � } | d k r,t j | � r� | j | � qv n xU t | � j D]" } | | � } | d k r� Pq� q� Wt d t | � j | f � � n | | | � } | rv | t | � � | | � qv qv W| S( Ni R R+ s bad argument type: %s(%r)( R( t getR R R" R R R R R# t iselementt appendt __mro__t TypeErrort __name__( R) R t childrenR R.
