代理在每个Datalist节点上迭代，并使用clientid和partybranchid的值创建另一个请求，并发送到另一个数据服务：

这是正确的配置
这是我的意外：
  <outSequence>
     <aggregate id="iterate1">
        <completeCondition>
           <messageCount min="-1" max="-1"/>
        </completeCondition>
        <onComplete xmlns:s12="http://www.w3.org/2003/05/soap-envelope"
                    xmlns:add="http://ws.wso2.org/dataservice"
                    xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/"
                    expression="//add:Addresses/add:Address">
           <log level="full"/>
        </onComplete>
     </aggregate>
     <xslt key="conf:/xslt/Tranformacion_DS_to_ESB.xsl"/>
     <send/>
  </outSequence>

  <outSequence>
     <property name="root" scope="default">
        <root:rootelement xmlns:root="http://ws.wso2.org/dataservice"/>
     </property>
     <aggregate id="iterate1">
        <completeCondition>
           <messageCount min="-1" max="-1"/>
        </completeCondition>
        <onComplete xmlns:s12="http://www.w3.org/2003/05/soap-envelope"
                    xmlns:add="http://ws.wso2.org/dataservice"
                    xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/"
                    expression="//add:Addresses/add:Address"
                    enclosingElementProperty="root">
           <log level="full"/>
        </onComplete>
     </aggregate>
     <xslt key="conf:/xslt/Tranformacion_DS_to_ESB.xsl"/>
     <send/>
  </outSequence>



正如您所看到的，我将一个根属性rootelement作为聚合消息的根，并在onComplete配置中使用enclosuringElementProperty=“root”，因此我的聚合输出现在如下所示：

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">

问题是，您对XSLT中介的请求没有根元素。也就是说，在soap主体中，所有三个
元素都处于同一级别。它们没有根元素。当esb将消息发送到xslt时，它将传递正文消息。在这里，xslt将只选择第一个元素并进行转换。要克服这个问题，请使用包装根元素创建soap主体。
例如：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.samples" xmlns:xsd="http://services.samples/xsd">
   <soapenv:Header/>
   <soapenv:Body>

注意：使用正确的xpath编辑xslt。关于配置/信封问题，我刚刚发现另一篇SO帖子提到了此类问题并提供了一种方法。不确定是否适用，但只是想分享一下，以防这会有所帮助：谢谢，我会尝试这种方法，然后带着results@JorgeInfanteOsorio在聚合中介程序结束后记录聚合中介程序的输出。就在发送到xslt中介并查看记录的消息格式之前。然后，您可以轻松地识别issue@Ratha输出在我的帖子中，没有问题，我用它来测试XMLSPY，XSL结果很好，问题与ESB有关。@JorgeInfanteOsorio我发布了答案。请检查
