 can be used for that purpose), whereas keywords arguments are added as
 attributes:
 >>> doc(tag.br)
 <Element "p">
->>> print doc
+>>> print(doc)
 <p>Some text and <a href="http://example.org/">a link</a>.<br/></p>
 If an attribute name collides with a Python keyword, simply append an underscore
 to the name:
 >>> doc(class_='intro')
 <Element "p">
->>> print doc
+>>> print(doc)
 <p class="intro">Some text and <a href="http://example.org/">a link</a>.<br/></p>
 As shown above, an `Element` can easily be directly rendered to XML text by
 printing it or using the Python ``str()`` function. This is basically a
 shortcut for converting the `Element` to a stream and serializing that
 stream:
 >>> stream = doc.generate()
 >>> stream #doctest: +ELLIPSIS
 <genshi.core.Stream object at ...>
->>> print stream
+>>> print(stream)
 <p class="intro">Some text and <a href="http://example.org/">a link</a>.<br/></p>
 The `tag` object also allows creating "fragments", which are basically lists
 of nodes (elements or text) that don't have a parent element. This can be useful
 returns an object of type `Fragment`:
 >>> fragment = tag('Hello, ', tag.em('world'), '!')
 >>> fragment
 <Fragment>
->>> print fragment
+>>> print(fragment)
 Hello, <em>world</em>!

 """Simple XML output generator based on the builder pattern.
 Construct XML elements by passing the tag name to the constructor:
->>> print Element('strong')
+>>> print(Element('strong'))
 <strong/>
 Attributes can be specified using keyword arguments. The values of the
 arguments will be converted to strings and any special XML characters
 escaped:
->>> print Element('textarea', rows=10, cols=60)
+>>> print(Element('textarea', rows=10, cols=60))
 <textarea rows="10" cols="60"/>
->>> print Element('span', title='1 < 2')
+>>> print(Element('span', title='1 < 2'))
 <span title="1 &lt; 2"/>
->>> print Element('span', title='"baz"')
+>>> print(Element('span', title='"baz"'))
 <span title="&#34;baz&#34;"/>
 The " character is escaped using a numerical entity.
 The order in which attributes are rendered is undefined.
 If an attribute value evaluates to `None`, that attribute is not included
 in the output:
->>> print Element('a', name=None)
+>>> print(Element('a', name=None))
 <a/>
 Attribute names that conflict with Python keywords can be specified by
 appending an underscore:
->>> print Element('div', class_='warning')
+>>> print(Element('div', class_='warning'))
 <div class="warning"/>
 Nested elements can be added to an element using item access notation.
 The call notation can also be used for this and for adding attributes
 using keyword arguments, as one would do in the constructor.
->>> print Element('ul')(Element('li'), Element('li'))
+>>> print(Element('ul')(Element('li'), Element('li')))
 <ul><li/><li/></ul>
->>> print Element('a')('Label')
+>>> print(Element('a')('Label'))
 <a>Label</a>
->>> print Element('a')('Label', href="target")
+>>> print(Element('a')('Label', href="target"))
 <a href="target">Label</a>
 Text nodes can be nested in an element by adding strings instead of
 elements. Any special characters in the strings are escaped automatically:
->>> print Element('em')('Hello world')
+>>> print(Element('em')('Hello world'))
 <em>Hello world</em>
->>> print Element('em')(42)
+>>> print(Element('em')(42))
 <em>42</em>
->>> print Element('em')('1 < 2')
+>>> print(Element('em')('1 < 2'))
 <em>1 &lt; 2</em>
 This technique also allows mixed content:
->>> print Element('p')('Hello ', Element('b')('world'))
+>>> print(Element('p')('Hello ', Element('b')('world')))
 <p>Hello <b>world</b></p>
 Quotes are not escaped inside text nodes:
->>> print Element('p')('"Hello"')
+>>> print(Element('p')('"Hello"'))
 <p>"Hello"</p>
 Elements can also be combined with other elements or strings using the
 addition operator, which results in a `Fragment` object that contains the
 operands:
->>> print Element('br') + 'some text' + Element('br')
+>>> print(Element('br') + 'some text' + Element('br'))
 <br/>some text<br/>
 Elements with a namespace can be generated using the `Namespace` and/or
 `QName` classes:
 >>> from genshi.core import Namespace
 >>> xhtml = Namespace('http://www.w3.org/1999/xhtml')
->>> print Element(xhtml.html, lang='en')
+>>> print(Element(xhtml.html, lang='en'))
 <html xmlns="http://www.w3.org/1999/xhtml" lang="en"/>
 """
 __slots__ = ['tag', 'attrib']
 def __init__(self, tag_, **attrib):
 self.attrib |= _kwargs_to_attrs(kwargs)
 Fragment.__call__(self, *args)
 return self
 def __repr__(self):
-return '<%s "%s">' % (self.__class__.__name__, self.tag)
+return '<%s "%s">' % (type(self).__name__, self.tag)
 def _generate(self):
 yield START, (self.tag, self.attrib), (None, -1, -1)
 for kind, data, pos in Fragment._generate(self):
 yield kind, data, pos
 A new element is created simply by accessing a correspondingly named
 attribute of the factory object:
 >>> factory = ElementFactory()
->>> print factory.foo
+>>> print(factory.foo)
 <foo/>
->>> print factory.foo(id=2)
+>>> print(factory.foo(id=2))
 <foo id="2"/>
 Markup fragments (lists of nodes without a parent element) can be created
 by calling the factory:
->>> print factory('Hello, ', factory.em('world'), '!')
+>>> print(factory('Hello, ', factory.em('world'), '!'))
 Hello, <em>world</em>!
 A factory can also be bound to a specific namespace:
 >>> factory = ElementFactory('http://www.w3.org/1999/xhtml')
->>> print factory.html(lang="en")
+>>> print(factory.html(lang="en"))
 <html xmlns="http://www.w3.org/1999/xhtml" lang="en"/>
 The namespace for a specific element can be altered on an existing factory
 by specifying the new namespace using item access:
 >>> factory = ElementFactory()
->>> print factory.html(factory['http://www.w3.org/2000/svg'].g(id=3))
+>>> print(factory.html(factory['http://www.w3.org/2000/svg'].g(id=3)))
 <html><g xmlns="http://www.w3.org/2000/svg" id="3"/></html>
 Usually, the `ElementFactory` class is not be used directly. Rather, the
 `tag` instance should be used to create elements.
