# PyQuery: a jQuery-like library for Python | |||
|
|||
PyQuery allows you to make [jQuery](http://jquery.com)-style CSS-selector queries on XML/HTML | |||
documents. The API is intended to match [jQuery's API](http://api.jquery.com) whenever possible, | |||
though it has been made more Pythonic where appropriate. | |||
|
|||
This [project](https://github.com/dsc/pyquery) is a fork of the [original](http://www.bitbucket.org/olauzanne/pyquery) | |||
PyQuery developed by Olivier Lauzanne in 2008; it is maintained by [David Schoonover](mailto:dsc@less.ly). Feedback and bug | |||
reports are both very welcome over on [github](https://github.com/dsc/pyquery/issues). | |||
|
|||
|
|||
## 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='http://google.com/') | |||
>>> # d = pq(url='http://google.com/', opener=lambda url: urllib.urlopen(url).read()) | |||
>>> d = pq(filename=path_to_html_file) | |||
|
|||
Now `d` is like the `$` object 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`, and `:file`. | |||
|
|||
>>> d('p:first') | |||
[<p#hello.hello>] | |||
|
|||
|
|||
## Notes | |||
|
|||
* PyQuery uses lxml for fast XML and HTML manipulation. | |||
* This is not a library to produce or interact with JavaScript code. If | |||
that's what you need, check out |
