I''ve got a web service which outputs XML. I''m generating it
very
conveniently by creating a file in the view named index.xml.builder.
That all works great, almost.
I can write that file very simply and cleanly like this:
xml.instruct!
xml.search do
xml.total @results[:total]
end
That''s really maintainable, but the output contains lots of extra
spaces and newlines that muck it up. I can get rid of all the spaces
by adding this line to the top of each xml.builder file:
xml = Builder::XmlMarkup.new
But that takes out ALL the spaces and newlines, so the entire output
is on one line. What I want is something in the middle. Through
experimentation, I''ve explicitly added newlines and spaces where I
want them, but suddenly the file is no longer as easily maintainable:
xml = Builder::XmlMarkup.new
xml.instruct!
xml.text!("\n")
xml.search do
xml.text!("\n ")
xml.total @results[:total]
end
Does anyone know of a cleaner approach where I get the maintainability
of the top example with the output of the bottom example?
Thanks!

I''m not sure how to insert pp after the view template. My controllers look like this: respond_to do |format| format.html format.xml end And I don''t understand the magic enough to know how to put pp in there. Also, I was looking at the documentation for pp and it''s not clear what it will do with a string in xml format. If I could solve the first problem I''ll experiment with it. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks. That''s where I started. That does two things: it indents the markup just like I want, but it does a second thing, too. It leaves all the white space that exists in the xml.builder file also, so that the resultant XML document is really ugly and contains extra newlines and extra spaces.
