for some reason, i am getting an extra:

\<?xml version = "1.0"?\>

in my xml file…

i am using a file called:

lastLogins.rxml

and the code looks like:

xml = Builder::XmlMarkup.new  
xml.instruct! :xml, :version=\>“1.0”, :encoding =\> ‘ISO-8859-1’

xml.loginData do  
@lastLogins.each do |login|  
xml.entry do  
xml.user(login.user)  
xml.timestamp(login.timestamp)  
end  
end  
end

this ends up inserting both headers:

\<?xml version = "1.0"?\> \<- from some mystery location..

and:

\<?xml version="1.0" encoding="ISO-8859-1"?\> \<- as specified by builder

followed by all the correct data with the correct layout…

anyone have any ideas?

thanks so much!

## I think this is your culprit. Usually you don’t need to create a builder explicitly.

i just tried it without that line, and i still get the header…

here is the code i just tried:

xml.loginData do  
@lastLogins.each do |login|  
xml.entry do  
xml.user(login.user)  
xml.timestamp(login.timestamp)  
end  
end  
end

\<?xml version = "1.0"?\> \<- this header was included...
