Copy Code code as follows:
From pyquery import Pyquery as PQ
DOC=PQ (url= ' http://movie.douban.com/subject/3530403/')
Data=doc ('. pl ')
For I in data:
Print PQ (i). Text ()
Output
Copy Code code as follows:

Usage
Users can use the Pyquery class to load an XML document from a string, lxml object, file, or URL:
Copy Code code as follows:
>>> from pyquery import Pyquery as PQ
>>> from lxml import etree
>>> DOC=PQ (">>> DOC=PQ (etree.fromstring (">>> DOC=PQ (Filename=path_to_html_file)
>>> doc=pq (url= ' http://movie.douban.com/subject/3530403/')
You can select objects like jquery.
Copy Code code as follows:
>>> doc ('. Pl ')
[<span.pl>, <span.pl>, <span.pl>, <span.pl>, <span.pl>, <span.pl>, <span.pl ", <span.pl>, <span.pl>, <span.pl>, <span.pl>, <span#rateword.pl>, <span.pl> <span.pl>, <span.pl>, <span.pl>, <span.pl>, <span.pl>, <span.pl>, <p.pl>]
In this way, the object class for ' pl ' is all selected.
However, when you use iterations, you need to encapsulate the text:
Copy Code code as follows:
For Para in Doc ('. pl '):
PARA=PQ (para)
Print Para.text ()

The text you get here is a Unicode code, which you need to encode as a string if you want to write to the file.
Users can use some of the pseudo classes provided by jquery (but do not yet support CSS) to operate, such as:
Copy Code code as follows:
>>> doc ('. Pl:first ')
[<span.pl>]
>>> Print doc ('. Pl:first '). Text ()
Director
Attributes
Get Properties of HTML element
Copy Code code as follows:
>>> p=pq (' <p id= "Hello" class= "Hello" ></p> ") (' P ')
>>> p.attr (' id ')
' Hello '
>>> p.attr.id
' Hello '
>>> p.attr[' id ']
' Hello '
assigning values
Copy Code code as follows:
>>> p.attr.id= ' plop '
>>> p.attr.id
' Plop '
>>> p.attr[' id ']= ' ola '
>>> p.attr.id
' Ola '
>>> p.attr (id= ' Hello ', class_= ' Hello2 ')
[<p#hello.hell0>]
Traversing
Filter
Copy Code code as follows:
>>> d=pq (' <p id= "Hello" class= "Hello" ><a/>hello</p><p id= "test" ><a/>world </p> ')
>>> d (' P '). Filter ('. Hello ')
[<p#hello.hello>]
>>> d (' P '). Filter (' #test ')
[<p#test>]
>>> d (' P '). Filter (lambda i:i==1)
[<p#test>]
>>> d (' P '). Filter (lambda i:i==0)
[<p#hello.hello>]
>>> d (' P '). Filter (lambda I:PQ (this). Text () = = ' Hello ')
[<p#hello.hello>]
Select in order
Copy Code code as follows:
>>> d (' P '). EQ (0)
[<p#hello.hello>]
>>> d (' P '). EQ (1)
[<p#test>]
Select inline Element
Copy Code code as follows:
>>> d (' P '). EQ (1). Find (' a ')
[<a>]
Select parent Element
Copy Code code as follows:
>>> D=PQ (' <p><span><em>Whoah!</em></span></p><p><em> There</em></p> ')
>>> d (' P '). EQ (1). Find (' em ')
[<em>]
>>> d (' P '). EQ (1). Find (' em '). End ()
[<p>]
>>> d (' P '). EQ (1). Find (' em '). End (). Text ()
' There '
>>> d (' P '). EQ (1). Find (' em '). End (). End ()
[<p>, <p>]
