hello,  
this is my sintra code can any one tell why xml isn’t been generated on  
browser

####### this is my sinatra code############

get ‘/multiquery.xml’ do  
content\_type(‘text/xml’)  
array\_of\_names = params[:name]  
‘#{construct\_xml(array\_of\_names)}’  
end

the method construct\_xml look like this

def construct\_xml(names)  
xml = Builder::XmlMarkup.new(:indent =\>1)  
xml.instruct!  
names.each do |name|  
xml.queryresponse {  
xml.name “#{name}”  
xml.credential “Engineer”  
}  
end  
return xml  
end

Now the point is that the method “construct\_xml” construct the  
appropriate xml  
but the the xml doesn’t appear in browser  
and the line of code ‘#{construct\_xml(array\_of\_name)}’ run into “XML  
Parsing Error: not well-formed”

iam sure that xml is formed properly.i mean to say the i have set the  
:target =\> $stdout

like this  
Builder::XmlMarkup.new(:target =\>$stdout ,:indent =\>1)  
and the xml is constructed properly in console  
ent .Is there any thing that I am missing.

please reply

thanks anyway

You use single quotes. Those are not interpolated.

If you do “#{construct\_xml(array\_of\_names)}”, everything should work.

Better, don’t use quotes for no reason:

construct\_xml(names)

“array\_of\_” is equally useless. plural implies a collection.

Yes, there is something REALLY OBVIOUS that you’re missing. A test.

The SIMPLEST of tests would have made this entire question obvious.
