我正在尝试使用mechanize + nokogiri解析脚本标记中的值。这是我能够得到的
1.9.3-p125 :107 > agent.page.search("script")[7]
=> #<Nokogiri::XML::Element:0x3ff1e10f3ff8 name="script" attributes=
[#<Nokogiri::XML::Attr:0x3ff1e10f3f80 name="type" value="text/javascript">] children=

如何将所有countdownFactory.create元素放入哈希？谢谢！
答案 0 :(得分：6)
Nokogiri没有进行JavaScript解析，但是使用正则表达式解析起来并不难：
element = agent.page.search("script")[7]
text = element.text # not 100% sure on this line. Just need the script text though.
Hash[text.scan(/countdownFactory.create\('(\d+)', '(\d+)', ''\)/)]
