【python】lxml-The E-factory

lxml中的E-factory可以用个简单快速的生成XML和HTML

>>> from lxml.builder import E

>>> def CLASS(*args): # class is a reserved word in Python

...     return {"class":' '.join(args)}

>>> html = page = (

...   E.html(       # create an Element called "html"

...     E.head(

...       E.title("This is a sample document")

...     ),

...     E.body(

...       E.h1("Hello!", CLASS("title")),

...       E.p("This is a paragraph with ", E.b("bold"), " text in it!"),

...       E.p("This is another paragraph, with a", "\n      ",

...         E.a("link", href="http://www.python.org"), "."),

...       E.p("Here are some reservered characters: <spam&egg>."),

...       etree.XML("<p>And finally an embedded XHTML fragment.</p>"),

...     )

...   )

... )

>>> print(etree.tostring(page, pretty_print=True))

<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

      <a href="http://www.python.org">link</a>.</p>

    <p>Here are some reservered characters: &lt;spam&amp;egg&gt;.</p>

    <p>And finally an embedded XHTML fragment.</p>

  </body>

</html>
