Question

我已使用此命令将xml文件发送到名为SRA-ENA的Web服务。

 submission_field = Curl::PostField.content(File.read("xml/#{@experiment.alias}.submission.xml"), 'SUBMISSION')
      study_field = Curl::PostField.content(File.read("xml/#{@experiment.alias}.study.xml"), 'STUDY')
      sample_field = Curl::PostField.content(File.read("xml/#{@experiment.alias}.sample.xml"), 'SAMPLE')
      run_field = Curl::PostField.content(File.read("xml/#{@experiment.alias}.run.xml"), 'RUN')
      experiment_field = Curl::PostField.content(File.read("xml/#{@experiment.alias}.experiment.xml"), 'EXPERIMENT')
      # Send these requests to the test-SRA website
      request_test = Curl::Easy.http_post("https://www-test.ebi.ac.uk/ena/submit/drop-box/submit/?auth=ERA%20era-drop-81%20dxjf2dntWDr4CHg28qERORnv0RQ%3D", submission_field, study_field, sample_field, run_field, experiment_field )

为此，我收到了来自网络服务器的xml格式的收据，

请有人指导我如何在变量中保存此xml，以便我可以使用nokogiri进一步解析xml文件。

这是一个独立的例子，使用Rails 2.3.14，它展示了如何使用nokogiri来解析XML结果。

require 'nokogiri'
require 'curb' 

# I have included this part so that this serves as a standalone example 

ce = Curl::Easy.new("http://www.myexperiment.org/announcements.xml") 
ce.perform 

# This is the part that deals with parsing the XML result using nokogiri

doc = Nokogiri::XML::Document.parse(ce.body_str)

doc.xpath("/announcements/announcement").each do |announcement|
  puts announcement.content
end

通过第三方Web服务收集xml响应
