Subject: Problems with SOAP: duplicate XML declarations

Hi,

I'm trying to implement a SOAP client using the native Ruby SOAP
client library.  Here's the relevant bit of code:

     XSD::Charset.encoding = 'UTF8'                       # Set
encoding
     wsdlfile = "http://ws.interfax.net/dfs.asmx?wsdl"     # WSDL
location
     driver =
SOAP::WSDLDriverFactory.new(wsdlfile).create_rpc_driver     # Create
driver

# and set up

# methods
     driver.wiredump_dev = STDERR # output SOAP transactions to STDERR
     @result = driver.SendCharFax({:Username => username, :Password =>
password, :FaxNumber => destinationfaxnumber, :Data =>
'hello', :FileType => ''})

For some reason, this is sending XML with two XML declarations!  Here
is what it is sending:

<?xml version="1.0" encoding="utf-8" ?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <env:Body>
<?xml version="1.0" encoding="UTF-8"?>
<hash>
 <Password>pass123</Password>
 <FaxNumber>001801751234</FaxNumber>
 <FileType></FileType>
 <Data>hello</Data>
 <Username>faxuser</Username>
</hash>
 </env:Body>
</env:Envelope>

I've tried to figure out what's going, tried searching Google and also
asked another Ruby developer, but neither of us have a clue why it's
doing this.

Can anybody point me in the right direction?

Cheers,

Jon
