Ways to return XML from function in SoapServer function?

[goatslayer]

Hi,

I'm struggling with a webservice at the moment. I can invoke the service from multiple clients and get a response. The problem is the server seems to be returning the XML that I want it to return but it is stripping the content of xml that contains attributes so:

<Element attr="123">123</Element>

Becomes:

<Element attr="123" />

SOAP UI can connect to the WSDL and generate a dummy output and it suggests the output should be as expected but when the web service itself returns to SOAP UI content is stripped.

I use PHP Pear Unserializer to read the XML in and it seems to put everything nicely in an array. I fear the array cannot be parsed properly by the server code.

Are there any alternatives to returning an array from Unserializer for returning XML from the webservice?
