>>> 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", " ", ... 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: <spam&egg>.</p> <p>And finally an embedded XHTML fragment.</p> </body> </html>
