the text same. can copy , paste resulting string other form , post it. works fine somewhere i'm missing because function not string.

attention if haven't record $weborderxml value null exception shown

fatal error: uncaught exception 'exception' message 'string not parsed xml'

because simplexmlelement() null give in. can check $weborderxml value empty() $weborderxml not null , can put simplexmlelement() inside of try catch control exception 

if(!empty($weborderxml)){   try{       $sxml = new simplexmlelement($weborderxml);   }catch(exception $e){       //show error or work   } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
