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.

It can be used for many purposes, one idea that I might try in the future is to use it for templating with pure http templates that you modify using pyquery. I can also be used for web scrapping or for theming applications with Deliverance.

The project is being actively developped on a mercurial repository on Bitbucket. 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 bitbucket 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='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 $ 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>]
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
