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 = "InterFax Web Service; # 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&quot;    xmlns:env="Error;    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&quot;&gt; <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 PS: This is the first application I've written in Ruby.. so don't discount obvious solutions :wink:

I haven't done too much SOAP, but what I have done, I did pretty much exactly the way you did. So, this looks like a bug to me. You might want to post this to the Ruby list... Also, the Ruby soap implementation is otherwise known as SOAP4r and it has a trac and some help here:

If you figure it out, please do post it here!

Thanks, I was rather confused about all the different SOAP libraries around, so thanks for telling me what soap4r is. It looks like a bug to me too, but I didn't think I was doing anything particularly unusual so I suspected my ineptitude more than a bug in a well-used piece of code.

I'll post it to the Ruby list... signing up via Google Groups didn't work so I guess I'll have to do it the old-fashioned way.

Cheers,

Jon
