Suzanne, It looks like a namespace thing. Because "username" exists in the http://trade.com namespace, you need to define that in the XPath expression.
XPath expressions are not the best where it comes to handling default namespaces. If you define an extra namespace expression in soap:Envelope of xmlns:tc="http://trade.com"; and then use the expression SimpleXPathAPI mysoap.xml / //tc:username you will select all the "username" nodes in the document that exist in the trade.com namespace.
