通过第三方Web服务收集xml响应 [英] Collect xml response by third party web service

问题描述

我已使用此命令将xml文件发送到名为SRA-ENA的Web服务.

I have used this command to send xml files to a web service named SRA-ENA.

 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 )

对此，我从Web服务器收到xml格式的收据，

In response to this, I receive a receipt from the web server in xml format,

请有人指导我如何将xml保存到变量中，以便我可以使用nokogiri进一步解析xml文件.

Please could some one guide me how to save this xml in a variable so that I can use nokogiri to further parse the xml file.

推荐答案

下面是一个使用Rails 2.3.14的独立示例，该示例显示了如何使用nokogiri解析XML结果.

Here is a standalone example, using Rails 2.3.14, that shows how to use nokogiri to parse XML results.

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
