pyquery: a jquery-like library for python

pyquery allows you to make jquery queries on xml documents. The API is as much as possible the similar to jquery. pyquery uses lxml for fast xml and html manipulation.

This is not (or at least not yet) a library to produce or interact with javascript code. I just liked the jquery API and I missed it in python so I told myself "Hey let's make jquery in python". This is the result.

The project is being actively developped on a git repository on Github. I have the policy of giving push access to anyone who wants it and then to review what he does. So if you want to contribute just email me.

Please report bugs on the github issue tracker.

Quickstart

You can use the PyQuery class to load an xml document from a string, a lxml document, from a file or from an url:

>>> from pyquery import PyQuery as pq
>>> from lxml import etree
>>> import urllib
>>> d = pq("<html></html>")
>>> d = pq(etree.fromstring("<html></html>"))
>>> d = pq(url=your_url)
>>> d = pq(url=your_url,
...        opener=lambda url, **kw: urlopen(url).read())
>>> d = pq(filename=path_to_html_file)

Now d is like the $ in jquery:

>>> d("#hello")
[<p#hello.hello>]
>>> p = d("#hello")
>>> print(p.html())
Hello world !
>>> p.html("you know <a href='http://python.org/'>Python</a> rocks")
[<p#hello.hello>]
>>> print(p.html())
you know <a href="http://python.org/">Python</a> rocks
>>> print(p.text())
you know Python rocks

You can use some of the pseudo classes that are available in jQuery but that are not standard in css such as :first :last :even :odd :eq :lt :gt :checked :selected :file:

>>> d('p:first')
[<p#hello.hello>]
