Hi all
n = Nokogiri::HTML("<h1>H1</h1>")
n.to_s
# => <!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0
Transitional//EN\"
\"http://www.w3.org/TR/REC-html40/loose.dtd\">\n<html><body><h1>H1</h1></body></html>
Is there a method that only outputs the stuff I''ve read, and not the
whole valid XHTML stuff?
Needed output:
<h1>H1</h1>
Thanks a lot
Josh

Thank you, guys. I didn''t know that Nokogiri creates a complete (X)HTML DOM when reading an incomplete structure. Have a great day! -- Posted via http://www.ruby-forum.com/.
Joshua Muheim wrote:> Thank you, guys. I didn''t know that Nokogiri creates a complete (X)HTML > DOM when reading an incomplete structure. > > Have a great day!Another question. I don''t get Nokogiri to produce XHTML. So for example I get unclosed tags like <hr> instead of <hr />. I found some options (http://nokogiri.rubyforge.org/nokogiri/Nokogiri/XML/ParseOptions.html) but I don''t really know how to get them to work... -- Posted via http://www.ruby-forum.com/.
