You can also add content to the end of tags:

>>> d = pq('<p class="hello" id="hello">you know Python rocks</p>')
>>> d('p').append(' check out <a href=""><span>reddit</span></a>')
>>> print(d)
<p class="hello" id="hello">you know Python rocks check out <a href=""><span>reddit</span></a></p>

Or to the beginning:

>>> p = d('p')
>>> p.prepend('check out <a href="">reddit</a>')
>>> print(p.html())
check out <a href="">reddit</a>you know ...

Prepend or append an element into an other:

>>> d = pq('<html><body><div id="test"><a href="">python</a> !</div></body></html>')
>>> p.prependTo(d('#test'))
>>> print(d('#test').html())
<p class="hello" ...

Insert an element after another:

>>> p.insertAfter(d('#test'))
>>> print(d('#test').html())
<a href="">python</a> !

Or before:

>>> p.insertBefore(d('#test'))
>>> print(d('body').html())
<p class="hello" id="hello">...

Doing something for each elements:

>>> p.each(lambda i, e: pq(e).addClass('hello2'))

Remove an element:

>>> d = pq('<html><body><p id="id">Yeah!</p><p>python rocks !</p></div></html>')
>>> d.remove('p#id')
>>> d('p#id')

Remove what’s inside the selection:

>>> d('p').empty()

And you can get back the modified html:

>>> print(d)

You can generate html stuff:

>>> from pyquery import PyQuery as pq
>>> print(pq('<div>Yeah !</div>').addClass('myclass') + pq('<b>cool</b>'))
<div class="myclass">Yeah !</div><b>cool</b>

Remove all namespaces:

>>> d = pq('<foo xmlns=""></foo>')
>>> d
>>> d.remove_namespaces()
