I am making the following request:
uri = URI.parse(url)
session = Net::HTTP.new(uri.host, uri.port)
headers = {}
res = session.start do |http|
http.get(request_url, headers)
end
Response looks like this:
<string xmlns="http://xxx">
some string
</string>
Is there some fast solution to parse the above response and get that some string. I can get it using a regexp but I would like use something which exists in Ruby.
Use any XML parser. For example, nokogiri:
require 'nokogiri'
n = Nokogiri::HTML::parse response
parsed_string = n.xpath('//string').text
As Arup Rakshit commented, use nokogiri to parse the xml:
require 'nokogiri'
res = <<EOS
<string xmlns="http://xxx">
some string
</string>
EOS
root = Nokogiri.parse(res)
root.at_xpath('.//*[local-name()="string"]').text.strip # Using xpath
# => "some string"
root.at_css('string').text.strip # Using css selector
# => "some string"
You can parse that XML using REXML or SimpleXML, and get the string.
I prefer SimpleXML.
data['Result'].each do |item|
item.sort.each do |k, v|
if ["Title", "Url"].include? k
print "#{v[0]}" if k=="Title"
print " => #{v[0]}\n" if k=="Url"
end
end
end
Nokogirito parseres.
