Hello

I am trying to create and read an xml. But I am not able to store them  
on a map.

I think so:  
xml = Builder:: XmlMarkup.new(:target =\> ‘./inf.xml’, :indent =\> 1)  
xml.id (1)

But I do not know how to save it in the path q I want. Neither as open  
and read it.

Thank you

I’m guessing you probably have this solved by now, but just in case…

> ```

Here you are setting the target of a Build::XmlMarkup object to the  
string ‘./inf.xml’ I’m guessing that’s not what you really want.  
Although, I would guess that Ruby isn’t complaining about that since  
your target is an object that responds to the \<\< method.

Try something like this:

f = File.new(“./inf.xml”, “w”)  
xml = Builder::XmlMarkup.new(:target =\> f, :indent =\> 1)  
xml.instruct!  
xml.some\_tag  
f.close
