PyQuery complete API

用来筛选

• PyQuery.eq(index)[source]

>>> d = PyQuery('<p class="hello">Hi</p><p>Bye</p><div></div>')>>> d('p').eq(0)[<p.hello>]>>> d('p').eq(1)[<p>]>>> d('p').eq(2)[]

• PyQuery.find(selector)[source]

>>> m = '<p><span><em>Whoah!</em></span></p><p><em> there</em></p>'>>> d = PyQuery(m)>>> d('p').find('em')[<em>, <em>]>>> d('p').eq(1).find('em')[<em>]

• PyQuery.filter(selector)[source]

>>> d = PyQuery('<p class="hello">Hi</p><p>Bye</p>')>>> d('p')[<p.hello>, <p>]>>> d('p').filter('.hello')[<p.hello>]>>> d('p').filter(lambda i: i == 1)[<p>]>>> d('p').filter(lambda i: PyQuery(this).text() == 'Hi')[<p.hello>]>>> d('p').filter(lambda i, this: PyQuery(this).text() == 'Hi')[<p.hello>]

• PyQuery.items(selector=None)[source]

>>> d = PyQuery('<div><span>foo</span><span>bar</span></div>')>>> [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('<span><p class="hello">Hi</p><p>Bye</p></span>')>>> d[<span>]>>> d.children()[<p.hello>, <p>]>>> d.children('.hello')[<p.hello>]

• PyQuery.parents(selector=None)

>>> d = PyQuery('<span><p class="hello">Hi</p><p>Bye</p></span>')>>> d('p').parents()[<span>]>>> d('.hello').parents('span')[<span>]>>> d('.hello').parents('p')[]

• PyQuery.closest(selector=None)[source]

>>> d = PyQuery(...  '<div class="hello"><p>This is a '...  '<strong class="hello">test</strong></p></div>')>>> d('strong').closest('div')[<div.hello>]>>> d('strong').closest('.hello')[<strong.hello>]>>> d('strong').closest('form')[]

• PyQuery.end()[source]

>>> m = '<p><span><em>Whoah!</em></span></p><p><em> there</em></p>'>>> d = PyQuery(m)>>> d('p').eq(1).find('em').end().end()[<p>, <p>]

• PyQuery.nextAll(selector=None)[source]

>>> h = '<span><p class="hello">Hi</p><p>Bye</p><img scr=""/></span>'>>> d = PyQuery(h)>>> d('p:last').nextAll()[<img>]# 注意这里的：last，用来选择最后一个匹配

• PyQuery.prevAll(selector=None)[source]

>>> h = '<span><p class="hello">Hi</p><p>Bye</p><img scr=""/></span>'>>> d = PyQuery(h)>>> d('p:last').prevAll()[<p.hello>]

• PyQuery.outerHtml()[source]

>>> d = PyQuery('<div><span class="red">toto</span> rocks</div>')>>> print(d('span'))<span class="red">toto</span> rocks>>> print(d('span').outerHtml())<span class="red">toto</span>>>> S = PyQuery('<p>Only <b>me</b> & myself</p>')>>> print(S('b').outerHtml())<b>me</b># 注意，取span会取到后面的text，outerHtml就只取span

• PyQuery.siblings(selector=None)[source]

>>> h = '<span><p class="hello">Hi</p><p>Bye</p><img scr=""/></span>'>>> d = PyQuery(h)>>> d('.hello').siblings()[<p>, <img>]>>> d('.hello').siblings('img')[<img>]

用来判断

• PyQuery.hasClass(name)[source]

>>> d = PyQuery('<div class="myclass"></div>')>>> d.hasClass('myclass')True

• PyQuery.is_(selector)[source]

>>> d = PyQuery('<p class="hello">Hi</p><p>Bye</p><div></div>')>>> d('p').eq(0).is_('.hello')True>>> d('p').eq(1).is_('.hello')False

• PyQuery.not_(selector)[source]

>>> d = PyQuery('<p class="hello">Hi</p><p>Bye</p><div></div>')>>> d('p').not_('.hello')[<p>]

获取内容

• PyQuery.text(value=)[source]

>>> doc = PyQuery('<div><span>toto</span><span>tata</span></div>')>>> 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()
