Harser是一个简单的PythonHTML解析器。
安装：pipinstallharser
示例代码：
>>> from harser import Harser>>> HTML = ''' <html><body> <div class="header" id="id-header"> <li class="nav-item" data-nav="first-item" href="/nav1">First item</li> <li class="nav-item" data-nav="second-item" href="/nav2">Second item</li> <li class="nav-item" data-nav="third-item" href="/nav3">Third item</li> </div> <div>First layer <h3>Lorem Ipsum</h3> <span>Dolor sit amet</span> </div> <div>Second layer</div> <div>Third layer <span class="text">first block</span> <span class="text">second block</span> <span>third block</span> </div> <span>fourth layer</span> <img /> <div class="footer" id="id-foobar" foobar="ab bc cde"> <h3 some-attr="hey"> <span id="foobar-span">foo ter</span> </h3> </div> </body></html>'''>>> harser = Harser(HTML)>>> harser.find('div', class_='header').children(class_='nav-item').find('text').extract()# Or just# harser.find(class_='nav-item').find('text').extract()['First item', 'Second item', 'Third item']>>> harser.find(class_='nav-item').get_attr('href').extract()['/nav1', '/nav2', '/nav3']# It is equally>>> harser.find('div', class_='header', id='id-header')>>> harser.find('div', attrs={'class': 'header', 'id': 'id-header'})>>> harser.find(id__contains='bar').get_attr('class').extract()['footer']>>> harser.find(href__not_contains='2').find('text').extract()['First item', 'Third item']>>> harser.find(attrs={'data-nav__contains': 'second'}).next_siblings().find('text').extract()['Third item']>>> harser.find('li').parent().next_siblings(filters={'text__contains': 'Second'}).clean_extract()['<div>Second layer</div>']>>> harser.find('h3', filters={'span.@id__starts_with': 'foo'}).get_attr('some-attr').extract()['hey']>>> harser.find('div').children('h3').xpath'//descendant::div/h3'
