Invalid Soap request gets created

Ruby
1

Hello Team,
I am using savon to create SOAP request’s, below is the code

response = newclient.request :soap, :copy_into_items do
soap.body ={“SourceUrl” =>srcpath,
“DestinationUrls” => [“string” =>docpath],
“Fields” =>
{:FieldInformation =>“”, :attributes! => {:FieldInformation=>
{:Type=>“Text”,:DisplayName=>“description”, :InternalName =>
“description”, :Value=>“testDesc”} }},
“Stream” => enc
}
end

Below is the request created with above code

<?xml version="1.0" encoding="UTF-8"?><env:Envelope

xmlns:xsd=“http://www.w3.org/2001/XMLSchema”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”
xmlns:tns=“http://schemas.microsoft.com/sharepoint/soap/”
xmlns:env=“http://schemas.xmlsoap.org/soap/envelope/”
xmlns:ins0=“http://schemas.microsoft.com/sharepoint/soap/”>
env:Body
ins0:CopyIntoItems
ins0:SourceUrlD:\baba\Baba.txt</ins0:SourceUrl>
ins0:DestinationUrls
ins0:stringhttp://sitename/test/Baba.txt</ins0:string>
</ins0:DestinationUrls>ins0:Fieldsins0:FieldInformation
</ins0:FieldInformation></ins0:Fields>ins0:StreamQmFiYQ==
</ins0:Stream></ins0:CopyIntoItems></env:Body></env:Envelope>

in above request if you see the xml tag FieldInformation it dosent have
any attribute assoicated with it, same is working fine if i change the
tag name to any other value e.g FieldInformation1, then the response i
am getting is as expected i.e. all attributes are added, i tried with
many other strings its perfectly working but only fails if the tag name
is FieldInformation

<?xml version="1.0" encoding="UTF-8"?><env:Envelope

Value=“testDesc”></tns:FieldInformation1>
</ins0:Fields>ins0:StreamQmFiYQ==
</ins0:Stream></ins0:CopyIntoItems></env:Body></env:Envelope>

This is very strange behavior, if any one has any idea then please
reply, thanks in advance
