I have following request to be created in my SOAP API and using this gem https://github.com/inossidabile/wash_out/
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Header>
<OGHeader xmlns="http://example.com">
</OGHeader>
</soap:Header>
<soap:Body>
<BookingRequest xmlns="http://example.com/Booking.wsdl">
<Reservation Action="CREATE">
<UniqueIDList xmlns="http://example.com/Unique/">
<UniqueID type="FAR" xmlns="www.uio.com/Common/">201801111429</UniqueID>
</UniqueIDList>
</Reservation>
</BookingRequest >
</soap:Body>
</soap:Envelope>
How to use wash_out to create such request with particular namespace defined in each xmlns?
