我有这个ruby脚本收集46344 xml-links,然后在每个xml文件中收集16个元素节点。进程的最后一部分是将其存储在CSV文件中。我遇到的问题是需要很长时间。这需要1-2个多小时..
这是没有包含所有XML链接的链接的脚本,我不能提供链接,因为它的公司东西......我希望它很酷。
这是脚本,它可以工作,但需要很长时间:

require 'nokogiri'
require 'open-uri'
require 'rexml/document'
require 'csv'

如果是网络访问,您可以开始对其进行线程化和/或开始使用可以使用处理器上所有内核的Jruby。如果你不得不经常这样做,你将不得不制定一个最好的服务,而不会阻塞。“/ p>
