I need to truncate some data received from a URI:PARSE…it is full of html

  • 0

I need to truncate some data received from a URI:PARSE…it is full of html codes and data, The result at the end is what I need.

Here’s the string (abbreviated) ‘ junk“Result”>Q8:0;junk

What’s is the best way to truncate the extra stuff in the string so that I can split the data I need into variables.

Thanks in advance,
Philip

    i would recommend to use Nokogiri to extract your value from Result span:

    require 'nokogiri'

response = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">;
<html xmlns="w3.org/1999/xhtml"><head><title>;
</title></head><body>
<form name="form1" method="post" action="tenHSServer.aspx?t=34&amp;f=DeviceValue&amp;d=R10" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTkzNDcxNzcwM2RkM4AHUDZdWZytDdspzLq7+FOXRfQ=" />
</div>
<span id="Result">R10:100;</span>
</form></body>
</html>'

result = nil
if doc = Nokogiri::HTML(response) rescue nil
  if span = doc.css('#Result')
    result = span.text
  end
end

puts result
#=> R10:100;

    however if you can not / do not want to install Nokogiri, use this regexp instead:

    result = response.scan(/id=["|']Result["|']>([^<]*)<\//m).flatten.first
puts result
#=> R10:100;
