我正在尝试使用 mechanize + nokogiri 解析脚本标记中的值。这是我能得到的范围内

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！

【解决方案1】：

Nokogiri 不做 JavaScript 解析，但这用正则表达式解析并不难：

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\('(\d+)', '(\d+)', ''\)/)]

谢谢，我最终只是用正则表达式解析它。现在工作得很好。 :)
