    from pyquery import PyQuery as pq

    d = pq(url='http://hi.baidu.com/tombkeeper/')
    d.make_links_absolute()
    lasers = d('.a-title')

    获取class为a-title的内容后，如果直接.attr('href')只能返回第一个链接，怎么才能返回里面的全部链接呢？
  • 链接
  • title
  • pyquery

    for url in lasers:
    print url.attrib['href']

    @lijie0427 多谢，已经可以返回全部的链接了。

    请问attrib['href']这一个写法在哪里有相应的介绍吗？我想看一看。

    pyquery底层调用的是lxml库。
    http://lxml.de/api/index.html
    你看那个lxml.html.HtmlElement
