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](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](http://www.w3.org/2001/XMLSchema)”  
xmlns:env=“[http://schemas.xmlsoap.org/soap/envelope/](http://schemas.xmlsoap.org/soap/envelope/)”  
xmlns:xsi=“[http://www.w3.org/2001/XMLSchema-instance](http://www.w3.org/2001/XMLSchema-instance)”\>  
env:Body

\<?xml version="1.0" encoding="UTF-8"?\> pass123 001801751234 hello faxuser 

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 😉

What version of soap4r are you using? The versions from  
soap4r-1.5.5.20070519 to soap4r-1.5.5.20070605 try to call ‘to\_xml’  
method of parameters. Later versions try to call ‘to\_xmlpart’ instead  
of ‘to\_xml’. Just updating soap4r should solve the problem.

Yay! I updated all my gems (“gem update”) including soap4r, restarted  
the server and voila! Correct XML and it’s all working again 🙂

Thanks for your help!

Cheers,

Jon
