Newlines in attributes

[Avin Mathew]

I'm trying to parse newlines in attributes, but it seems they are converted to spaces:

>> require 'nokogiri'

=> true

>> Nokogiri::XML("<root attr=\"value\n\with\nspaces\"/>").to_xml

=> "<?xml version=\"1.0\"?>\n<root attr=\"value with spaces\"/>\n"

I did come across this related post (https://www.ruby-forum.com/topic/361457), but I don't think the question was resolved. Newlines in attributes seem to be valid characters (http://stackoverflow.com/questions/449627/are-line-breaks-in-xml-attribute-values-valid).

Is this a bug or am I missing a parse option?

Try using single quotes instead of double quotes. ie 

Nokogiri::XML('<root attr=\"value\n\with\nspaces\"/>').to_xml

Using single quotes would just put a literal backslash and "n" character in the string, see http://en.wikibooks.org/wiki/Ruby_Programming/Strings#Single_quotes

Using a heredoc produces the same result:

>> require 'nokogiri'

=> true

>> xml = <<EOS

<root attr="value

with

newlines"/>

EOS

=> "<root attr=\"value\nwith\nnewlines\"/>\n"

>> Nokogiri::XML(xml).to_xml

=> "<?xml version=\"1.0\"?>\n<root attr=\"value with newlines\"/>\n"
