Question

I have an xml tag that needs to be formatted like so:

<AddDealRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 

I can’t seem to get this to work properly, using builder. I am attempting the following code in builder:

xml.AddDealRequest(:xmlns:xsi => "http://www.w3.org/2001/XMLSchema-instance", :xmlns:xsd => "http://www.w3.org/2001/XMLSchema" ) do

but obviously that second colon is throwing off the symbol. Is there any way to escape that second symbol? Or is this declaration entirely necessary?

Thanks!

Answer 1

Try quoting your symbols:

xml.AddDealRequest(
    :'xmlns:xsi' => "http://www.w3.org/2001/XMLSchema-instance",
    :'xmlns:xsd' => "http://www.w3.org/2001/XMLSchema"
)

You could also try using strings instead of symbols

xml.AddDealRequest(
    'xmlns:xsi' => "http://www.w3.org/2001/XMLSchema-instance",
    'xmlns:xsd' => "http://www.w3.org/2001/XMLSchema"
)

but I don’t know if builder will be happy with that but the documentation includes things like this:

xm.target("name"=>"compile", "option"=>"fast")
# => <target option="fast" name="compile"\>

so strings for the attribute names should work.

A bit of time in irb might be help clarify things:

>> 'where_is:pancakes_house'.to_sym
=> :"where_is:pancakes_house"

>> :'xmlns:xsi'.to_s
=> "xmlns:xsi"
