Problem reading XML with Nokogiri

Question

My Ruby script is supposed to read in an XML doc from a URL and check it for well-formedness, returning any errors. I have a sample bad XML document hosted with the following text (from the Nokogiri tutorial:

<?xml version="1.0"?>
  <root>
    <open>foo
      <closed>bar</closed>
  </root>

My test script is as follows (url refers to the above xml file hosted on my personal server):

require 'nokogiri'

document = Nokogiri::XML(url) 

puts document
puts document.errors

The output is:

<?xml version="1.0"?>
Start tag expected, '<' not found

Why is it only capturing the first line of the XML file? It does this with even with known good XML files.

Answer 1

It is trying to parse the url, not its content. Please, take into account that first parameter to Nokogiri::XML must be a string containing the document or an IO object since it is just a shortcut to Nokogiri::XML::Document.parse as stated here.

EDIT: For reading from an uri

require 'open-uri'
open(uri).read
