Manipulating¶
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="http://reddit.com/r/python"><span>reddit</span></a>')
[<p#hello.hello>]
>>> print(d)
<p class="hello" id="hello">you know Python rocks check out <a href="http://reddit.com/r/python"><span>reddit</span></a></p>
Or to the beginning:
>>> p = d('p')
>>> p.prepend('check out <a href="http://reddit.com/r/python">reddit</a>')
[<p#hello.hello>]
>>> print(p.html())
check out <a href="http://reddit.com/r/python">reddit</a>you know ...
Prepend or append an element into an other:
>>> d = pq('<html><body><div id="test"><a href="http://python.org">python</a> !</div></body></html>')
>>> p.prependTo(d('#test'))
[<p#hello.hello>]
>>> print(d('#test').html())
<p class="hello" ...
Insert an element after another:
>>> p.insertAfter(d('#test'))
[<p#hello.hello>]
>>> print(d('#test').html())
<a href="http://python.org">python</a> !
Or before:
>>> p.insertBefore(d('#test'))
[<p#hello.hello>]
>>> print(d('body').html())
<p class="hello" id="hello">...
Doing something for each elements:
>>> p.each(lambda i, e: pq(e).addClass('hello2'))
[<p#hello.hello.hello2>]
Remove an element:
>>> d = pq('<html><body><p id="id">Yeah!</p><p>python rocks !</p></div></html>')
>>> d.remove('p#id')
[<html>]
>>> d('p#id')
[]
Remove what’s inside the selection:
>>> d('p').empty()
[<p>]
And you can get back the modified html:
>>> print(d)
<html><body><p/></body></html>
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="http://example.com/foo"></foo>')
>>> d
[<{http://example.com/foo}foo>]
>>> d.remove_namespaces()
[<foo>]
