收集第三方Web服务的xml响应

Question

我已经使用此命令将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) 

在回答这个问题，我收到一张收据从XML格式的Web服务器，

请可有人指导我如何保存这个XML的变量，这样我可以使用引入nokogiri进一步解析xml文件。

Answer 1

这是一个独立的例子，使用Rails 2.3.14，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
