在调用端点之前，如何将标签有条件地插入肥皂请求主体中？

Question

我想根据某种条件将标签添加到肥皂请求主体中

，应在 ActionProperties 标签下添加标签

，因此我尝试使用以下方式使用Enrich Mediator：

<filter regex="false" source="get-property('IsValid')">
    <then>
    <enrich>
      <source clone="true" type="inline">
         <p857:Property propertyId="isArchived" settable="0" xsi:type="p857:SingletonString" 
           xmlns:p857="http://www.filenet.com/ns/fnce/2006/11/ws/schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
                <p857:Value>1</p857:Value>
           </p857:Property>
      </source>
      <target

      action="child" 
      type="custom" xpath="//p857:ExecuteChangesRequest/p857:ChangeRequest/p857:ActionProperties" />
   </enrich>
   </then>
        <else/>
   </filter>

                                        <p857:Property propertyId="Content" settable="0" xsi:type="p857:ContentData">

            </soapenv:Envelope>
        </format>
        <args>
            <arg evaluator="xml" expression="get-property('Username')"/>
            <arg evaluator="xml" expression="get-property('Password')"/>
            <arg evaluator="xml" expression="get-property('ObjectStore')"/>
            <arg evaluator="xml" expression="get-property('DocumentClass')"/>
            <arg evaluator="xml" expression="get-property('FileName')"/>
            <arg evaluator="xml" expression="get-property('FileData')"/>
            <arg evaluator="xml" expression="get-property('ContentType')"/>
        </args>
    </payloadFactory>

但是我始终遇到错误：无效的目标对象要丰富

我能够通过在PayloadFactory标签之后添加 renrich 标签来解决：

<enrich>
        <source clone="true" type="inline">
            <p857:Property propertyId="isArchived" settable="0" 
            xmlns:p857="http://www.filenet.com/ns/fnce/2006/11/ws/schema" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="p857:SingletonString">
                <p857:Value>1</p857:Value>
            </p857:Property>
        </source>
        <target action="child" xmlns:p857="http://www.filenet.com/ns/fnce/2006/11/ws/schema" 
        xpath="//p857:ExecuteChangesRequest/p857:ChangeRequest/p857:ActionProperties"/>
    </enrich>
