Import::

    >>> from pyquery import PyQuery as pq


Assume spaces normalization::

    >>> pq('<ul> <li>  </li> </ul>').text()
    ''

    >>> print(pq('<ul> <li> toto </li> <li> tata </li> </ul>').text())
    toto tata

Complex wrapping::

    >>> d = pq('<div id="bouh"><span>youhou</span></div>')
    >>> s = d('span')
    >>> s is d
    False
    >>> s.wrap('<div><div id="wrapper"></div></div>')
    [<div>]

We get the original doc with new node::

    >>> print(d)
    <div id="bouh"><div><div id="wrapper"><span>youhou</span></div></div></div>

Complex wrapAll::

    >>> doc = pq('<div><span>Hey</span><span>you !</span></div>')
    >>> s = doc('span')
    >>> s.wrapAll('<div id="wrapper"></div>')
    [<div#wrapper>]

    >>> print(doc)
    <div><div id="wrapper"><span>Hey</span><span>you !</span></div></div>
