如何获取mule中的XML值？

在Mule中，我使用的是SOAP组件，它以XML格式接收WSDL文件。之后，我想获取XML数据。但它显示错误。我在这里使用如何获取mule中的XML值？

#[message.InboundProperties['Subject']]

它显示空值。这是我的XML代码

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:out="http://soap.sforce.com/2005/09/outbound" xmlns:urn="urn:sobject.enterprise.soap.sforce.com"> 
    <soapenv:Header/> 
    <soapenv:Body> 
     <out:notifications> 
     <out:OrganizationId>00D9XXXXXXXXXXXx</out:OrganizationId> 
     <out:ActionId>04k90xxxxxx</out:ActionId> 
     <out:SessionId>XXXXXXXXXXXXXXX</out:SessionId> 
     <out:EnterpriseUrl>https://ap1.salesforce.com/services/Soap/c/29.0/00D90000000q0Mc</out:EnterpriseUrl> 
     <out:PartnerUrl>https://ap1.salesforce.com/services/Soap/u/29.0/00D90000000q0Mc</out:PartnerUrl> 
     <!--1 to 100 repetitions:--> 
     <out:Notification> 
      **<out:Id>?</out:Id> 
      <out:sObject> 
       <!--Zero or more repetitions:--> 
       <urn:fieldsToNull>?</urn:fieldsToNull> 
       <!--Optional:--> 
       <urn:Subject>Test</urn:Subject> 
      </out:sObject>** 
     </out:Notification> 
     </out:notifications> 
    </soapenv:Body> 
</soapenv:Envelope>

SOAP正常工作。 <urn:Subject>Test</urn:Subject>从这个XML文件
