用scrubyt抓取酷讯最新火车票信息
关键字: scrubyt screen-scaping
用scrubyt写的一个简单的小例子，scrubyt看起来真的很不错，不过现在bug也非常的多，特别是对xpath的支持。
require 'rubygems'
require 'scrubyt'
Scrubyt.logger = Scrubyt::Logger.new
kooxoo_data = Scrubyt::Extractor.define do
fetch "http://piao.kooxoo.com/"
fill_textfield 'vFrom', '北京'
fill_textfield 'to', '广州'
submit
record"//tbody/tr" do
col1 "/td[@class='col1']" do
url "href", :type => :attribute
end
col2 "/td[@class='col2']"
col3 "/td[@class='col3']"
col4 "/td[@class='col6']"
col5 "/td[@class='col7']"
end
end
kooxoo_data.to_xml.write(open('result.xml', 'w'))
