Question

我正在编写一个解析XML的应用程序。我必须从一个XML文件中获取数据，然后在循环中我必须打开另一个XML文件。

代码如下所示：

$doc = Nokogiri::XML(open('myxmladress'))
$doc.xpath('//job').each do |job|
  if job.xpath('name').text.include?('joe')
    $doc2 = Nokogiri::XML(open('myxmladress_for_joe'))
  end
end

我相信我不能打开多个HTTP连接。

我可以简单地下载整个文件而不是使用

$doc Nokogiri::XML(open('myxmladress'))

或者有没有办法关闭Nokogiri HTTP连接？

我还要通过https下载它。

我的错误：

您正在使用OpenUri从URL获取文档。我很确定这不会留下任何打开的连接，但会将文档读入类似IO的对象，有点像文件。

您的问题似乎是服务器出现了内部错误。

下载多个XML文件
