使用Selenium从网页获取所有可见文本

使用lxml，您可以尝试如下操作：

import contextlibimport selenium.webdriver as webdriverimport lxml.html as LHimport lxml.html.clean as cleanurl="http://www.yahoo.com"ignore_tags=('script','noscript','style')with contextlib.closing(webdriver.Firefox()) as browser:    browser.get(url) # Load page    content=browser.page_source    cleaner=clean.Cleaner()    content=cleaner.clean_html(content)        with open('/tmp/source.html','w') as f:       f.write(content.enpre('utf-8'))    doc=LH.fromstring(content)    with open('/tmp/result.txt','w') as f:        for elt in doc.iterdescendants(): if elt.tag in ignore_tags: continue text=elt.text or '' tail=elt.tail or '' words=' '.join((text,tail)).strip() if words:     words=words.enpre('utf-8')     f.write(words+'n')

除了图像中的文字和随时间变化的某些文字（使用javascript完成并刷新）之外，这似乎可以获取www.yahoo.com上几乎所有的文字。
