Orbeon将实例数据发送到web服务

Question

我为web服务调用和响应创建了一个实例。

<xf:instance id="ws-request-instance">                         
                            <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.estat.zzi.si/">
                               <soapenv:Header/>
                               <soapenv:Body>
                                  <ws:orbeonGet>
                                     <dokumentId/>
                                     <type/>
                                     <formData/>
                                  </ws:orbeonGet>
                               </soapenv:Body>
                            </soapenv:Envelope>
</xf:instance>

<xf:instance id="ws-response-instance">                       
                            <soapenv:Envelope>
                            </soapenv:Envelope>
</xf:instance>

提交函数调用创建的服务，如下所示：

<xf:submission id="submit" action="http://was7test.zzi.si:8081/EStat-RO-WS-91-XX/orbeon" method="post" ref="instance('ws-request-instance')" replace="instance" mediatype="application/soap+xml" instance="ws-response-instance">
                <xf:message ev:event="xforms-submit-done" level="modal">Done Result:<xf:output value="instance('ws-response-instance')"/>
                <xf:output value="event('error-type')"/>; Status: <xf:output value="event('response-status-code')"/>; URI: <xf:output value="event('resource-uri')"/>; Headers: <xf:output value="event('response-headers')"/>; Body: <xf:output value="event('response-body')"/>
                </xf:message>

                <xf:message ev:event="xforms-submit-error" level="modal">
                A submission error occurred: <xf:output value="event('error-type')"/>; Status: <xf:output value="event('response-status-code')"/>; URI: <xf:output value="event('resource-uri')"/>; Headers: <xf:output value="event('response-headers')"/>; Body: <xf:output value="event('response-body')"/>
                </xf:message>
            </xf:submission>

当单击submit按钮时，我们像这样填写web服务调用的参数：

<xf:action ev:event="submit-form">
            <xf:setvalue ref="instance('ws-request-instance')//type" value="xxf:get-request-parameter('type')"/>
            <xf:setvalue ref="instance('ws-request-instance')//dokumentId" value="xxf:get-request-parameter('documentId')"/>
            <xf:setvalue ref="instance('ws-request-instance')//formData" value="instance('fr-form-instance')"/>
            <xf:send submission="submit"/>
</xf:action>

在formData参数中，我希望获得fr-form-instance的"XML“数据。例如，实例是"X"，而我只得到X，而不是XML中的整个“实例”。

这是可能的吗？你能指引我到正确的方向吗？

我只是使用了"saxon“，并写道：

<xf:setvalue
    ref="instance('ws-request-instance-get')//formData"
    value="saxon:serialize(instance('fr-form-instance'), 'xml')"/>
