PyQuery complete API
用来筛选
- PyQuery.eq(index)[source]
>>> d = PyQuery('Hi
Bye
')
>>> d('p').eq(0)
[]
>>> d('p').eq(1)
[]
>>> d('p').eq(2)
[]
- PyQuery.find(selector)[source]
>>> m = 'Whoah!
there
'
>>> d = PyQuery(m)
>>> d('p').find('em')
[, ]
>>> d('p').eq(1).find('em')
[]- PyQuery.filter(selector)[source]
>>> d = PyQuery('Hi
Bye
')
>>> d('p')
[, ]
>>> d('p').filter('.hello')
[]
>>> d('p').filter(lambda i: i == 1)
[]
>>> d('p').filter(lambda i: PyQuery(this).text() == 'Hi')
[]
>>> d('p').filter(lambda i, this: PyQuery(this).text() == 'Hi')
[]
- PyQuery.items(selector=None)[source]
>>> d = PyQuery('foobar')
>>> [i.text() for i in d.items('span')]
['foo', 'bar']
>>> [i.text() for i in d('span').items()]
['foo', 'bar']用来上下查找
- PyQuery.children(selector=None)[source]
>>> d = PyQuery('Hi
Bye
')
>>> d
[]
>>> d.children()
[, ]
>>> d.children('.hello')
[]
- PyQuery.parents(selector=None)
>>> d = PyQuery('Hi
Bye
')
>>> d('p').parents()
[]
>>> d('.hello').parents('span')
[]
>>> d('.hello').parents('p')
[]- PyQuery.closest(selector=None)[source]
>>> d = PyQuery(
... 'This is a '
... 'test
')
>>> d('strong').closest('div')
[]
>>> d('strong').closest('.hello')
[]
>>> d('strong').closest('form')
[] - PyQuery.end()[source]
>>> m = '<p><span><em>Whoah!em>span>p><p><em> thereem>p>'
>>> d = PyQuery(m)
>>> d('p').eq(1).find('em').end().end()
[<p>, <p>]- PyQuery.nextAll(selector=None)[source]
>>> h = 'Hi
Bye
![]()
'
>>> d = PyQuery(h)
>>> d('p:last').nextAll()
[![]()
]
# 注意这里的：last，用来选择最后一个匹配- PyQuery.prevAll(selector=None)[source]
>>> h = 'Hi
Bye
![]()
'
>>> d = PyQuery(h)
>>> d('p:last').prevAll()
[] - PyQuery.outerHtml()[source]
>>> d = PyQuery('toto rocks')
>>> print(d('span'))
class="red">totospan> rocks
>>> print(d('span').outerHtml())
<span class="red">totospan>
>>> S = PyQuery('Only me & myself
')
>>> print(S('b').outerHtml())
<b>meb>
# 注意，取span会取到后面的text，outerHtml就只取span- PyQuery.siblings(selector=None)[source]
>>> h = 'Hi
Bye
![]()
'
>>> d = PyQuery(h)
>>> d('.hello').siblings()
[, ![]()
]
>>> d('.hello').siblings('img')
[![]()
]
用来判断
- PyQuery.hasClass(name)[source]
>>> d = PyQuery('')
>>> d.hasClass('myclass')
True- PyQuery.is_(selector)[source]
>>> d = PyQuery('Hi
Bye
')
>>> d('p').eq(0).is_('.hello')
True
>>> d('p').eq(1).is_('.hello')
False- PyQuery.not_(selector)[source]
>>> d = PyQuery('<p class="hello">Hip><p>Byep><div>div>')
>>> d('p').not_('.hello')
[<p>]获取内容
- PyQuery.text(value=)[source]
>>> doc = PyQuery('tototata')
>>> print(doc.text())
toto tata- PyQuery.val(value=)[source]
>>> d.val()
'Youhou'- PyQuery.width(value=)[source]
- PyQuery.height(value=)[source]
注意
使用pyquery的时候，一定要注意namespace，可能找不到element。先移除doc = pq(html).remove_namespaces()
